Discovering Orchids: A Southeast WA Pub Crawl Adventure

List of Orchids Found, Numerous days, Pallarup NR, Road Trip, Western Australian Orchids

07/09/2024

Today is the day that our Pub Crawl around the Southeast of WA commences.
We head off in the Triton around 8.45 am and venture over to Nulsen to pick up our travelling companions for the adventure, Bob and Jan.
First stop is at the Munglinup1 Roadhouse, where I take the time to have a very quick check for orchids.

8 species are found, which is quite unbelievable.
First up, the reliable Cowslip orchid (Caladenia flava subsp. flava) is found.
Next is a large white spider orchid, which, given its location, I will name the Esperance white spider orchid (Caladenia longicauda subsp. crassa).
Thirdly is one of the smaller spider orchids from the Filamentosa complex. It is most likely the Common spider orchid (Caladenia varians).
Next is the small Zebra orchid (Caladenia cairnsiana).
The 5th orchid found is the Lemon-scented sun orchid (Thelymitra antennifera).
A not fully opened Purple enamel orchid (Elythranthera brunonis) is found next.
The 7th orchid for the day is the Dancing spider orchid (Caladenia discoidea).
Final and 8th orchid for this location is the Small mantis orchid (Caladenia attingens subsp. gracillima).


We now move on to the lookout on Ethel Daw Drive in the Ravensthorpe shire. Only 2 species were found along the roadside.
First up is the Western tiny blue orchid (Cyanicula aperta), followed by the Sugar orchid (Ericksonella saccharata).


Moving back to Elverdton Road, we head west and pull into a new location I will name Ravensthorpe1.
Walking along this dirt track, we locate 4 species, 1 new for the day.
Found again were the Small mantis orchid, Sugar orchid and Western tiny blue orchid.
The new species for the day is the Common dragon orchid (Caladenia barbarossa).
Terrible pictures were taken, so I will include only 2.


Passing through Ravensthorpe, will pull into Kukernup Memorial to have lunch.
After having a bite to eat, we all venture out to explore the walk trail.
It was a great spot, as we found 9 orchid species in flower.
First up is the Jug orchid (Pterostylis recurva),
Next, more Dancing spider orchids and Common dragon orchids are found.
Also found again were more Small mantis orchids, Lemon-scented sun orchids, Cowslip orchids and Purple enamel orchids.
Other new species found for the day are the Redbeak (Pyrorchis nigricans) and the Frog greenhood (Pterostylis sargentii).


We now backtrack to the road leading to Lake King and head north. Next stop is one of our all-time favourite places.
Pallarup Rocks picnic area provides loads of places to explore for orchids.
We are not disappointed with the species located.
First up are the Sugar orchid, Cowslip orchid, Jug orchid, Purple enamel orchid, and Lemon-scented sun orchid, which were all found earlier today at prior locations.


New species found start with the Ant orchid (Caladenia roei), quickly followed by the closely related Short-sepaled spider orchid (Caladenia brevisura) and Purple-veined spider orchid (Caladenia doutchiae).


The next new species found for the day was the Pink candy orchid(Caladenia hirta subsp. rosea) together with its hybrid – Tinged spider orchid(Caladenia x suffusa).
So, now to find the other possible parent of the hybrid. Due to the location, I believe the other parent to be the Pallarup white spider orchid (Caladenia longicauda subsp. ‘Pallarup’). Luckily specimens are found.


Once up on the granite rock we come across some donkey orchids. I believe them to be the Yellow granite donkey orchid (Diuris hazeliae). I have posted images of 3 orchids as they may represent another species.


A smaller whiteish spider orchid is found in various shades, however I feel they are all the Chameleon spider orchid (Caladenia dimidia).

Do you agree they are all one species?

Also found a nice bunch of what appears to be another orchid species, possibly the Central wheatbelt spider orchid (Caladenia sp. ‘central wheatbelt’) however is outside of the recorded location.

Thoughts?


Another frog greenhood is found however on closer inspection; it is actually a Little frog greenhood (Pterostylis occulta) due to the hairy narrow horn-like labellum structures.
2 pics posted to show this aspect as clearly as possible


Another new orchid for the day is the Little laughing leek orchid (Prasophyllum gracile) which is found growing in shallow soil on the granite.

Other random hybrids are found during the search, and I will post them below for record keeping. Assigning parents is always difficult for hybrids especially between the Roei and Filamentosa complexes.


Well that is our final orchid stop for the day, so it is off to our first hotel stay. Night 1 is spent at the Newdegate Hotel.
Checked out the Silo Art before settling in for the night.


23 species found with a possible 4 hybrids, plus a possible new species but outside its usual range.

Amazing first day !!!!

Day Trip, Western Australian Orchids

04/09/2024

Well, this has proven to be a full-on day trip looking for orchids. The last stop for the day is an East Munglinup location, though this time it’s on Jonegatup Road.

The first orchid found is the Small mantis orchid (Caladenia attingens subsp. gracillima), which has been a common orchid at various locations today.
Flowering occurs from August to October in woodlands and shrublands between Jerramungup and Israelite Bay.


Whilst capturing a photo of the Small mantis orchid, another smaller orchid is spied. Another better example is found soon after.
The Little frog greenhood (Pterostylis occulta) is found between Northampton and Ravensthorpe from late-August to October.
Our location is some 80kms to the east of Ravensthorpe, so a slight extension to its range.


Further along, a couple of specimens of the Zebra orchid (Caladenia cairnsiana) are found.
These small orchids occur between Lancelin and Esperance from August to early-November.


It was amazing to catch 2 species of orchids growing together. The Small mantis orchid was found under the watchful eye of the Common dragon orchid (Caladenia barbarossa).
The dragon orchid is found growing between Bindoon and Esperance from September to mid-November.


Appears to be the location for Caladenia species. Next up, we find the Short-sepaled spider orchid (Caladenia brevisura).
These orchids are found between Jerramungup and Israelite Bay during August and September.


5 other species were also spotted at this location.
4 were solo specimens:
Little laughing leek orchid (Prasophyllum gracile)
Sugar orchid (Ericksonella saccharata)
Western tiny blue orchid (Cyanicula aperta)
Common spider orchid (Caladenia varians)


Lastly was the Lemon-scented sun orchid (Thelymitra antennifera), which was found in a group, though not yet fully open.


So, our day trip finally comes to an end. We now need to drive the 112 kms home, but we do so with a sense of achievement.
This final location turned up 10 different orchid species, whilst over the whole day, we discovered at least 27 orchid species and at least 1 hybrid.
What a Day !!!!!

Top Orchids Found West of Esperance: A Field Report; Part II

Day Trip, Western Australian Orchids

04/09/2024

After a wonderful morning finding 15 species of orchids over numerous locations, we pull off the road to park up and enjoy lunch, from the boot of my small Toyota Corolla (Fili).
Neds Corner Rd is the border between the locations of Coomalbidgup and East Munglinup.
So, our lunch is in East Munglinup8, being West of the road however our explorations take us to the East side as well, which technically is in Coomalbidgup.
Not too confusing I trust. ๐Ÿ™‚

After lunch we hit the surrounding area for another orchid hunt. Very close by we find our first orchids for the afternoon.
The Zebra orchid (Caladenia cairnsiana) is found growing between Lancelin and Esperance from August to early-November.


Red beaks (Pyrorchis nigricans) are usually found flowering the season after a summer fire has burnt its habitat. This is the case with this location, and they are found in great numbers.
Occur between Shark Bay and Israelite Bay from August to October.


Another orchid previously found today is also located at both sides of the road. The Small mantis orchid (Caladenia attingens subsp. gracillima) is found between Jerramungup and Israelite Bay during the period August to early-October.


A newbie for the day was next on the list. The tiny Little laughing leek orchid (Prasophyllum gracile) occurs between Shark Bay and Eyre during the period July to November.


An orchid which we always expect to find, but on occasions we are disappointed is the Cowslip orchid (Caladenia flava subsp. flava). Today we are not disappointed. In fact, we find hundreds growing on the banks of the Young River in the unburnt vegetation, whilst earlier we found sporadic ones growing in the bushfire zone.


In a bushfire regrowth area green with weeds and white sandy soil we find a great patch of the Esperance king spider orchid (Caladenia decora). These orchids range from Bremer Bay to Cape Arid from mis-August to October.


Another newbie and a surprise for the day is the Pink candy orchid (Caladenia hirta subsp. rosea) which occurs between Kalbarri and Israelite Bay from late-June to September.


Intermixed with the Cowslips was another yellow-coloured orchid. The Lemon-scented sun orchid (Thelymitra antennifera) is found between Shark and Israelite Bays from July to October.


As would be expected orchids found earlier today will also be found at this location being only 10km or so north. So further specimens of the Purple enamel orchid (Elythranthera brunonis) are found as they occur between Kalbarri and Israelite Bay from August to early-November.


A single king type spider orchid is found which does not appear to be the Esperance king spider orchid.
Due to the lack of red colouring and the drooping petals I will name this the Heberle’s spider orchid (Caladenia heberleana). These orchids are listed as occurring between Augusta and Cape Arid during September and October.
I have posted this ID on iNaturalist and will await other opinions.


Another solitary specimen is found, this time of the Pink fairies (Caladenia latifolia) which is found between Kalbarri and Israelite Bay from August to early-December.


Upon crossing the road, the first orchid found appears to be a hybrid. The parentage was hard to decipher until we found one of the parents close by.
I have decided the parents are Caladenia attingens x barbarossa.
Posted on iNaturalist for thoughts from others.


Just past the hybrid orchid we come across one of the parents. The Common dragon orchid (Caladenia barbarossa) is found scattered at the top of the ridge above the river flat.
These orchids are found between Bindoon and Esperance from September to mid-November.


Another orchid found as two separate specimens was the Beautiful donkey orchid (Diuris pulchella) which is listed as growing between Salmon Gums and Israelite Bay from July to September. The specimens were north and south of the river.
Our location is some 50km southwest of Salmon Gums but the species is recorded at this location in the Atlas of Living Australia.


As I was taking photos of orchids found Debbie is exploring further afield and she yells out excitedly.
She has come across a vast warren of the Rabbit orchid (Leptoceras menziesii) which has flowered due to the previous summer bushfire that scorched this area.
These orchids are found growing between Northampton and Israelite Bay from September to early-November.


Close by we also found the Esperance white spider orchid (Caladenia longicauda subsp. crassa) which occurs between Bremer and Israelite Bays from August to early-October.
Some may be the related Rigid white spider orchid (Caladenia longicauda subsp. rigidula) which occurs between Ravensthorpe and Israelite Bay during a similar flowering season.
The differences between the 2 species are the size of the flower and the rigidness or pendulousness of the petals and sepals.
Let me know your thoughts.


Crossing back over the river we come across more spider orchids that appear to be further Esperance king spider orchids.
However the better find was some other species of Donkey orchid. Due to the location and date found, I will be naming these the Green Range donkey orchid (Diuris littoralis) which is recorded as occurring between Denmark and Esperance from July to early-September.


Finally made it back to Fili at around 2pm and move onto another location.
16 species found at this location.
Part III to follow… Stay tuned

Top Orchids Found West of Esperance: A Field Report; Part I

Day Trip, Lake Mortijinup NR, Nature Reserves, Western Australian Orchids

















Only a little way up the road will pull over at another random spot due to a change in vegetation cover.
First up hiding underneath a shrub a compact clump of Western tiny blue orchids is found.


An exciting find here was a small patch of the Dwarf shell orchid (Pterostylis brevichila). These orchids are found flowering between Hyden and Mount Arid.


Another new orchid for today is found, from the Caladenia genus, which is always exciting. The Short-sepaled spider orchid (Caladenia brevisura) is another easterly located orchid, as it grows between Ravensthorpe and Israelite Bay.

The next orchids found are the small Zebra orchid (Caladenia cairnsiana) and the Frog greenhood (Pterostylis sargentii) which are found from Watheroo to Esperance and Mullewa to Grass Patch respectively.


Then some further Esperance white spider orchids and Small mantis orchids are found. As usual I will post a pic of each for recording purposes.


As we proceed, we take a moment to reflect on the discovery of 15 distinct species of orchids. With additional locations yet to be explored, this promises to be a highly successful orchid hunting expedition.
As I compose these blog posts several months after the actual date, I am dividing this day into three reports. Stay tuned for Part II and III.

08/10/2022 ….. Ongerup walkabout

Numerous days, Road Trip, Western Australian Orchids

After not too cold a night we awake to a beautiful day in the Ongerup Gardens Caravan Park. After cereal for breakfast, we decide to go exploring the woodlands behind the caravan park. We take what we believe to be a rough track, but it peters out soon enough, so we go bush bashing in an attempt to find it again. We end up curving north and head up past the sporting complex. We cross Jaekel Steet and follow the track/s to the Yongergnow Malleefowl Centre, where we grab a coffee, for the walk back to the caravan park. The orchid count for such a good walk was a bit disappointing, however we did find some, so I will record them now.

03/10/2022 ….. Sole specimen in Shadforth

Numerous days, Road Trip, Western Australian Orchids

After a very long drive from Esperance to Denmark, I check into my hotel before taking a quick drive west in a vain attempt to find orchids. As I am not familiar with the area, I pull over at a large granite rock covered in moss and rushes then hike up with expectations high. My expectations were however not met. I did discover only one sole orchid in flower. A Lemon-scented sun orchid (Thelymitra antennifera) was my saviour. These common sun orchids are found between Shark Bay and Israelite Bay, growing on creek margins, seasonally moist flats and granite outcrops.

17/09/2022 ….. Fishing Trip Findings

Cape le Grand NP, National Parks, Weekend away, Western Australian Orchids

It is the Esperance Offshore Fishing Club Classic and my brother, Geoff and Deb have entered the competition as have friends Bob and Tammy. So, a little group of 6 head out to Dunns Beach for an overnight beach camp, with some to try their luck. I am not a fisherperson so during Saturday afternoon I head into the dunes behind the beach to see if I can locate any orchids. Our son Tim turned up as well to fish into the night.


OK, so into the dunes I head. Immediately behind the first set of dunes the land was flooded, so had to work my way around this to get into the more stabilised dunes where some orchids may be found.


Finally made it to the stabilised dune system, which was densely vegetated, so it proved difficult to transverse. However, I was rewarded with great views, plus I actually found some orchids. Some were finished, others were in bud, but I still found 3 species in flower. I took photos of them all, however they are not great.

Firstly, found is a sole Banded greenhood (Pterostylis vittata) at the end of its flowering cycle. These orchids are known to flower in coastal heath between Perth and Balladonia. Next were orchids in bud, still to flower, which was frustrating. They appear to be Pink fairies (Caladenia latifolia) which are also listed as growing in coastal heath, though over a larger range, Kalbarri to Israelite Bay. Another orchid in bud was one from the Thelymitra genus plus another finished orchid from the Pterostylis genus, which seems to be a Snail orchid.


The next 3 orchids listed were found flowering … So happy to find flowering orchids. The Western tiny blue orchid (Cyanicula aperta) was found first. These small orchids are found between Dumbleyung and Mt Ragged, which seems to be more inland, so finding one in a coastal environment is special. A single Purple enamel orchid (Elythranthera brunonis) is found growing in a tangle of dead branches of a shrub. These bright orchids flower between Kalbarri and Israelite Bay which indicates coastal shrublands are an included habitat. Final orchid for the day was the Lemon-scented sun orchid (Thelymitra antennifera) which is listed as flowering between Shark Bay and Israelite Bay, growing in seasonally wet areas and creek lines, which covers off on the habitat I found it in.


I was not expecting to find 7 species to record as being located in the stabilised dunes behind Dunns Beach, which is located in Cape Le Grand National Park, which is great as I don’t have many records for that park listed in my previous blogs.

Back at camp the rest had started fishing with a few small fish caught. It was a beautiful sunset as is common out here on the beach, but I never grow tired of them. Deb does catch a nice sized Gummy shark later in the night. We are so spoilt to live in this beautiful and remote part of the country.
