30/08/2020 ….. Hamersley Inlet to Home (Road Trip 2020)

Fitzgerald River NP, Munglinup NR, National Parks, Nature Reserves, Road Trip, Springdale NR, Western Australian Orchids

We awake to a cold morning however the sun is shining so it will be a great last day of our 2020 Road Trip. First up we check out the spider orchid we found in the fading light yesterday.

Hamersley Inlet

Western wispy spider orchid

(Caladenia microchila)

Camper packed up and time to move on. We get as far as 4 Mile Beach campground before we stop and have a scout around. We only find a few Pterostylis orchids.

4 Mile Beach

Ravensthorpe snail orchid or Coastal snail orchid

(Pterostylis grossa or P. sp. “coastal snail”)

We head into Hopetoun for a bite to eat. Our next point of call is just north of the South Coast Hwy, and is a favourite of ours. We again find a few orchids for our troubles.

Mills Road

Zebra orchid

(Caladenia cairnsiana)

??? hybrid spider orchid

(Caladenia x sp.)

Small mantis orchid

(Caladenia attingens subsp. gracillima)

Cream spider orchid

(Caladenia horistes)

3 orchid species and a hybrid is not a bad haul, however we must keep moving towards home. First up though we stop at the Munglinup Roadhouse for a burger lunch. Driving in we discover some orchids on the roadside, so I jump out to get some photos and Deb heads down to order lunch.

Munglinup Townsite

Esperance white spider orchid

(Caladenia longicauda subsp. crassa)

Common bee orchid

(Diuris decrementa)

Lunch purchased, we move on to Munglinup Nature Reserve to eat and explore.

(Caladenia longicauda subsp. crassa)

Jug orchid

(Pterostylis recurva)

Five species found, so happy we made to time to explore the area. We now move on to revisit a location we checked out on Day 1 of this road trip. Lets see if there is anything different now flowering.

Springdale Nature Reserve

Since it is after 3 pm and we still have more than 100kms to home, we decide to leave our orchid exploration at this fruitful location. The hour long drive was a great time to look back on our awesome road trip that started back on the 8th August. The Wheatbelt Way was a great loop that opened up the amazing Western Australian countryside.

Over the 3 weeks on the road we discovered many new locations as well as re-visiting favourite spots. So many orchid species were located along with numerous hybrids which was a pleasant surprise.

08/08/2020 ….. Esperance to Corrigin (Road Trip 2020)

Nature Reserves, Overshot Hill NR, Pallarup NR, Road Trip, Springdale NR, Western Australian Orchids

Leaving Esperance at just after 7am we are finally on our way. This year I will be listing the orchids found at each stop on our journey. I will group the photos of a particular orchid together rather than post them in chronological order. If needed a little narrative about the trip may be added to a location based on anything that occurred on the way to it, during the visit itself or is planned after. Please provide me any feedback on this structure as I am open to suggestions how I can improve the blog or spice it up a bit… Thanks!!

Springdale Nature Reserve

This Nature Reserve was burnt out last summer and has proven this season to be successful in providing excellent orchid finds. Today is no exception.

Pink bunny orchid (Eriochilus scaber subsp. scaber)

Green Range donkey orchid

(Diuris littoralis)

Blue beard , Blue fairy orchid

(Pheladenia deformis)

Little pink fairy, Dwarf pink fairy

(Caladenia reptans subsp. reptans)

Reaching spider orchid

(Caladenia arrecta)

Mills Road verge

Turning into Mills road off the South Coast Hwy, west of Munglinup, we stop at one of our regular road verge stops. To our dismay the area had been graded so the usual orchid habitat was destroyed. Luckily some orchids seem to like disturbed ground, whilst other areas had missed the destruction.

Cream spider orchid

(Caladenia horistes)

Green Range donkey orchid

(Diuris littoralis)

Mallee banded greenhood

(Pterostylis arbuscula)



Overshot Hill Nature Reserve

Parking at the free overnight camping area we venture into the creekline to look for the orchids we had found here previously. Again we were not disappointed. Of particular interest were the dual flowered and green coloured Dwarf shell orchids.

Dwarf shell orchid

(Pterostylis brevichila)

Midget greenhood

(Pterostylis mutica)



Pallarup Nature Reserve

Another of our favourite spots, which always seems to have some orchids in flower.

17 different orchid species found today, not too shabby.

27/09/2020 ….. Peak Charles Long Weekend – Day 3

National Parks, Peak Charles NP, Weekend away, Western Australian Orchids

Well after a wet night we awake to a fine, cloudy day with white fast moving clouds covering the peak of Peak Charles. An amazing sight it is!!

After breakfast we jump in the Triton and head off south towards nearby Peak Elenore, where we plan to explore for orchids. Driving along the track southwards we come across a track leading west back towards the rocks so Deb decides to check it out. We come across someone camping so nearly just turned back but luckily I noticed we could bypass a fallen tree and get closer to the rocks. Pulling up alongside we venture into the rocky slope which is quite well vegetated and is still quite green. Might be due to being on the lee side of the hill.

Almost immediately green spider orchids are found. Two subspecies of Calendenia attingens are found in this area. They are very similar orchids with the main distinguishing feature being the lateral sepals. Small mantis orchid (Caladenia attingens subsp. gracillima) has upswept lateral sepals and the Granite mantis orchid (Caladenia attingens subsp. effusa) has barely upswept lateral sepals, plus the lamina calli of the Small mantis orchid extend further onto the red apex than other species, which assists with identification, however is still proves difficult.

In the midst of so many mantis orchids a Western wispy spider orchid (Caladenia microchila) is found. These orchids flower July to early October over an easterly range from Kondinin to Madura. They can be found growing around granite outcrops. Other specimens were found later on in the search of this location.

Another spider orchid is found which is proving more difficult to identify. The labellum has very dark distinct red lines and the petals and sepals are quite narrow. I will be naming these orchids the Ironcaps spider orchid (Caladenia paradoxa) which can be found on granite outcrops and is said to intergrade with C. microchila at the eastern extent of it’s distribution (Wubin to Norseman). Please correct me if I’m wrong as the distribution listed does not include Peak Charles specifically.

A rufous greenhood type orchid is the next found. Various specimens are found scattered around and they differ in colour, lateral sepals positions and general aspect. Naming these orchids is proving very difficult. The specimens with long thin apically upcurved lateral sepals could be the Striped rufous greenhood (Pterostylis zebrina) which is recorded as being found between Mt Ridley to Merredin growing on or near granite outcrops.

There is a brown coloured greenhood with much shorter lateral sepals that are quite hairy looking and quite square at the top rather than being rounded. Based on this I’ll name this specimen the Straight-topped rufous greenhood (Pterostylis sp. “straight tops”) which is located between the Murchison River and Peak Charles, our current location. However this orchid is not listed in the latest reference book so please correct me if you believe I am incorrect.

Many other rufous greenhoods were found and naming them is just too difficult, so I’m just uploading some pictures with the hope that someone can provide some guidance.

An unexpected find was the Sigmoid spider orchid (Caladenia sigmoidea). For very small orchids they are quite distinct with red and cream colourings and of course the ‘S’ shaped apex to the labellum, from which it derives it’s name.

Moving on, we head south towards Peak Elenore. We don’t go far before a change in vegetation makes up stop to have a look around. First up is a rufous greenhood orchid just budding up. Then further along another lone orchid is found, however this one is in full flower. Due to the long thin sepals this orchid could be a Slender rufous greenhood (Pterostylis macrosceles). It is recorded as growing between Goomalling and Queen Victoria Rocks, which is someway North of our current location, however Florabase records it as being in the Esperance shire, so I am happy with my ID.

After 30mins of searching, nothing else is found, so we move on. This time we stop in a white sandy patch to see if anything different can be found. After a few minutes with nothing found we move on and get to the Salmon Gum patch, where we were originally going to camp after finding the camping ground full. So happy we are camping where we are as this place is rather dry and barren. However there are orchids here. First up is the Insect-lipped rufous greenhood (Pterostylis insectifera) which is located between Karroun Hill, Ravensthorpe and Norseman. An exerted labellum and down-curved lateral sepals are distinctive features.

Another orchid found could very well be the Elegant rufous greenhood (Pterostylis elegantissima) due to the wide-spaced flowers and laterally-splayed lateral sepals. The labellum is almost blackish, dark green. Unfortunately, one of my specimens two flowers has a green labellum, which disagrees with my ID. However the orchids occur in locations between Goomalling and Salmon Gums, which concurs with my ID. Another case of ID confusion!

As it’s now 12.30ish we decide to give Peak Elenore a miss and head back to camp to grab a bite of lunch. After lunch the 2 Deb’s have a rest so I head off looking for a way up onto the rock. It is way too steep close to camp so I follow the base for quite a while. At one point I stumble across a small spider orchid growing a the base of the granite. Struggled to get some good photos but they are posted below just for recording purposes. By the off white colouring I believe it to be a Common spider orchid (Caladenia varians) which is found from Kalbarri to Esperance flowering from July till mid-October.

Nearby other rufous greenhoods were found. I think some are more Striped rufous greenhoods and one with cupped lateral sepals I am unsure of.

Not finding much else I decide to leave the rock s and head into the surrounding woodland/scrub to see if anything different is found. First up only more rufous greenhoods are found then by chance a small patch of Shy greenhoods (Pterostylis allantoidea) are found. The little guys belong to the snail orchid complex and flower in the area bordered by Ravensthorpe, Coolgardie and Israelite Bay, during August and September.

Stumbled across the remnants of a Caladenia roei complex orchid then on the track back to camp some more rufous greenhoods are found.

Peak Elenore will have to wait for another visit as time has gotten away from us and this is our last night camping. Appears the rufous greenhood orchids are the dominant orchid complex at Peak Charles N. P. at this late time of the season. It was still a pleasure finding them and getting out into the “Great Outdoors”.

25/09/2020 ….. Peak Charles Long Weekend – Day 1

Esperance, Helms Arboretum, National Parks, Nature Reserves, Peak Charles NP, Red Lake Townsite NR, Weekend away, Western Australian Orchids

It’s Friday before the Queens Birthday long weekend and I have taken another RDO, so as to make it extra long. A camping weekend at Peak Charles which is some 150kms or so NNW of Esperance is planned.

We pack up the Triton and camper trailer then head up to pick up Deb C. who rides shotgun with my darling Deb driving. We are taking Deb C. on her first ever trip North of Esperance. First point of call is the Esperance Bird and Animal Park for a takeaway coffee/hot chocolate and sweet slice. This was to give us energy for our first orchid hunting location, which just for a change is good old Helms Arboretum (Mud Map SE 35).

First orchids found alongside section 21, were the wonderful Cowslip orchid (Caladenia flava subsp. flava) , the Common bee orchid (Diuris decrementa) and the Lemon-scented sun orchid (Thelymitra anennifera) which are regular finds at this location. Oddly enough they are all yellow in colour.

Then just before hopping back in the Triton Deb spies a spider orchid in the overgrown Section 21, so we all go to investigate. We discover many beautiful large Esperance king spider orchids (Caladenia decora) in flower. The spreading petals that barely drop are a distinguishing feature when comparing them to the often co-located and similar Heberle’s spider orchid. Due to the lack of colour some may actually be hybrids with the Esperance white spider orchid.

Leaving Section 21 we head straight down to the track between Sections 1 and 2. Nothing much found along this track, however upon driving further we find the Rattle Beaks (Lyperanthus serratus) growing on the edge of Section 9. No longer right on the bull ants nest, thank goodness, but about 2 metres away. Only the one in flower though which was disappointing.
