09/08/2020 ….. Corrigin to Dowerin (Road Trip 2020)

Road Trip, Western Australian orchids

Corrigin Wildflower Trail

After a quick breakfast we break camp and head into Corrigin to top up the Triton. We then head straight out to the Scenic Lookout Drive followed by the Corrigin Wildflower Trail which surrounds the airfield.

After spending a few hours at this location, which included running into a fellow orchid enthusiast, we headed off to Dowerin where we have planned to meet up with Richard, our road trip buddy. We called into Watercarrin (Deb’s grandfather farmed here) and checked out Minnivale before finding Richard at the Dowerin Short Stay Village. We stayed in a chalet which was fortuitous as it rained all afternoon into the night.

Only got to check out near Corrigin today and it was so windy but we found a few orchids. I have posted a video below to show how windy it was today which made getting clear photos very difficult.

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

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

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.

Lake Varley NR, Nature Reserves, Numerous days, Pallarup NR, Road Trip

07/09/2019

We wake up to a beautiful sunny spring morning. A leisurely breakfast was enjoyed as we know our destination today, so no need to rush. It’s after 9am before we finally leave Flat Rock Nature Reserve and head off in an easterly direction down the Kulin-Holt Rock Road. We reach Lake Varley and pull over on the side of the road and decide to check out the flat granite outcrop, which we later find is a part of the Lake Varley Nature Reserve.

Deb finds the first orchid growing under the scrub at the edge of the rock. The wonderful yellow donkey orchids are again flowering at the edge of the rock under the protection of the scrubs. The Western wheatbelt donkey orchid (Diuris brachyscapa) is know to grow in the region with sightings recorded in Atlas of Living Australia. Kulin shire is also one of the Local Government Areas (LGA) listed in Florabase as being a location for this orchid. Links to these resources are found via the “+” sign at the bottom of every page.

Close by some wispy spider orchids are found. Due the creamy colouring of the flowers they appear to be the Cream spider orchid (Caladenia horistes) which flowers from August to early-October over an easterly range from Fitzgerald River National Park to Balladonia, however Kulin LGA is listed in Florabase as a location for this orchid.

Another yellow orchid pops up. The wonderful Cowslip orchid (Caladenia flava subsp. flava) is such a cheerful orchid to find. Bright yellow flowers with such random markings; from spots, stripes, blotches to barely none at all. This little grouping has mainly spots. The view back to the Triton provides an indication of the habitat we are exploring.

Other orchids found were a solitary Sugar orchid (Ericksonella saccharata) and Hairy-stemmed snail orchid (Pterostylis sp. ‘inland’) . Both have vast inland ranges and flower during September.

Then a perfect specimen of the Drooping spider orchid (Caladenia radialis) is found in all it’s glory. Another inland orchid but only found from Northampton to Jerramungup, so not as widespread as the Sugar or Hairy stemmed Snail orchids.

Well now the Ant orchid (Caladenia roei) turns up to entertain us. They are said to resemble a crucifix due to the petals and lateral sepals.

Then came across more Sugar orchids and a grouping of Western wheatbelt donkey orchids before finally heading back to the Triton. Last small orchids found were the Little laughing leek orchid (Prasophyllum gracile) which were camouflaged well in the moss on the granite rock.

Time to move onto our next place to explore. We detour a slight bit to check out Holt Rock. We drive into the day use area of Holt Rock but chose not to go for an exploration, though it looks like a great place to check out another time. Further south we arrive at Varley and go check out a place on the map named Dempster Rock. After a little searching we find a track into the approximate area. Looking out our windows we are rewarded with orchids.

Some old favourites were the first found. Sugar orchids and Jug orchids (Pterostylis recurva) . Both are common orchids but always a pleasure to find.

Then the spider orchids start jumping out of the woodlands. They have strong yellow tonings and therefore appear to be the Chameleon spider orchid (Caladenia dimidia) which flowers July to September in the range Paynes Find to Norseman. My references refer to them being yellow, cream or pink-red in colour with either a small pale yellow or pale white red striped labellum. Whiter specimens are found close by.

Identifying the spider orchids is difficult given many overlap in locations and they have similar features. The Western wispy spider orchid and the Ironcaps spider orchid both also have smaller labellums than others plus the Ironcaps spider orchid also varies in colour from creamy-white to pale yellow. All three orchids are shown as being located in the Varley area in the Atlas of Living Australia.

Now we do find other orchids as well, so I will mention these ones now before adding more varied spider orchid photos. Hairy-stemmed snail orchids, Blue beards (Pheladenia deformis), Little laughing leek orchids, sugar orchids and Western wheatbelt donkey orchids are found.

The most amazing find though was a Midget greenhood (Pterostylis mutica). The reason for my amazement – is it’s height of 190mm. The tallest I have ever seen. These orchids are found in all the states of Australia which is quite amazing.

Now back to these other spider orchids. Firstly we found more Drooping spider orchids or are they? Possible hybrid with the c. dimidia as the labellum is very pale in colour with smooth margins. So I will leave the actual identification for now.

Then other spider orchids found. Some in clumps and some in isolation but all beautiful as ever. Some white, whilst others had reddish tones. Any help in naming these would be appreciated.

Getting peckish, so we finally leave this great new location and head back to Varley then down to Lake King for a meal at the tavern. After a great counter lunch and beer, we cruise further south to one of our favourite patches, Pallarup Rock. Located in the Pallarup Nature Reserve this location proves a fruitful orchid patch on most visits. Today is no exception. Within minutes we locate the first of many orchids. The Pink candy orchid (Caladenia hirta subsp. rosea) is found in many colour variations. This first one is very pale but others are bright pink.

Next up we find some donkey orchids. The Western wheatbelt donkey orchid has been recorded in the Lake Grace shire whilst the other possible orchid, the Green Range donkey orchid is recorded in the Ravensthorpe shire which is nearer the coast. The basal leaves observed are not that wide which is causing me some angst in trying to ID them, so I will just posts the pics.

We now move onto the track to the water tank and at the junction find some more Sugar orchids. Then on the side of this track the first orchids found are Frog greenhoods (Pterostylis sargentii) which was named in honour of Oswald Sargent in 1905. He was an early West Australian orchidologist and pharmacist from York, where the specimen used to name it was collected in 1904.

Moving along the track the first of the spider orchids appear. The first one is an excellent example of the wispy complex. As there is one lonely specimen I will not attempt to name it, as there are too many variables with these wispy spider orchids. It could be one of three known to this location or a hybrid between two of them.

Close by is another spider orchid, but from the White spider orchid compex this time. As the sepals and petals are not that pendulous I believe this to be the Rigid white spider orchid (Caladenia longicauda subsp. rigidula) which is found between Ravensthorpe and Israelite bay from August to October. Florabase records Lake Grace and Dundas LGA’s as also being the location of this orchid, so 50kms north of Ravensthorpe in the Lake Grace shire seems appropriate.

EDIT: With thanks to Margaret’s assistance (refer comments) the ID has been clarified as an unnamed subspecies of Caladenia longicauda. I will provide my own common name as Pallarup Rock white spider orchid (Caladenia longicauda subsp. ‘Pallarup Rocks’). Exciting to find a new subspecies.

A small blue orchid catches Deb’s eagle eye. A lone china orchid is found. This pretty blue orchid has not been found in this location on any of our numerous prior visits, so this is an exciting find. Due to the darker blue colouring, scattered calli on labellum and the location this orchid must be the Blue china orchid (Cyanicula gemmata) which has the largest range of all china orchids in WA, being from Kalbarri to Israelite Bay. Flowering period is August to early-November. The one feature that did cause me confusion with the ID was the colour of the labellum, as the mostly blue labellum conflicted with the pictures in my references, which show the labellum as being mostly white or blue striped.

EDIT: With thanks to Margaret’s assistance (refer comments) the ID has been clarified as the Granite china orchid (Cyanicula nikulinskyae) which is restricted to a range between Fitzgerald River National Park and Israelite Bay. My location is 50kms north of this coastline. Flowering period is September to early-November.

Further white spider orchids were found and their features confirm my identification as Rigid white spider orchids. Also another wispy spider orchid is found and this one appears to be the Common spider orchid (Caladenia vulgata) which as the name suggests is found over a large area, from Kalbarri to Esperance, flowering during the period July to mid-October.

Next up we come across some Ant orchids. They are also known as Clown orchid, Man orchid and Jack-in-the Box.

More yellow patches are seen growing in the Pincushion plant (Borya constricta) and Sundew (Drosera). The Lemon-scented sun orchids (Thelymitra antennifera) are another widespread orchid which flower from July to October. The latin name antennifer (antennae) refers to the little lobes on the column.

Many more spider orchids are found together with patches of Cowslips and Blue beards popping up here and there. A wonderful kaleidoscope of colours.

A relative of the Ant orchid is also found in the scrub around the rock. The Short-sepaled spider orchid (Caladenia brevisura) is a common orchid found between Ravensthorpe to Israelite Bay. We have previously found these orchids east of Esperance at Condingup so we have now found them at both edges of their range.

Other orchids found in our exploration of Pallarup Rock are the Jug orchid, Little laughing leek orchid and Hairy-stemmed snail orchid (or is it?) .

4.30 in the afternoon so time to move on to Ravensthorpe for our overnight stay. We spend our last night of our road trip as we did on our first night. Staying with our son, Timothy in his little duplex unit in Ravensthorpe.

Went to bed happy to have discovered at least 19 species today, which is amazing. Also a tinge of sadness as tomorrow is our final day.

2019 Road Trip – Narembeen to Flat Rock Nature Reserve

Numerous days, Road Trip

06/09/2019

Whilst having breakfast we are walking around in the sunshine when I spy what appears to be a black poly pipe coming from the leach drain of the Septic Tank at the back of the toilets. However it then moved and scared the beejesus out of me. I called out to Deb who arrived in time to see it wriggle backwards back into its hole. Whoa we steer clear of that area as we pack up. We drove around the back of the toilets as we left and it was back out, sunning itself. It lifted it’s head to watch us move by.

So we now make our way further east to a place called Roe Dam. The dam was initially planned in 1929 but put off as too costly and was finally built in 1970/71, to provide the Mt Walker farming community with water. The catchment area is 140 acres (56ha) of granite rock and the dam holds 20 million gallons (91 million litres). We pull into the old picnic area as the dam area appears to be out of bounds. This old area has working toilets and shade to park up so all good. First stop for the day so off we go exploring.

First orchids found are the Hairy-stemmed snail orchids (Pterostylis sp. ‘inland’) which as the name suggests are easily identified by their hairy stem. Other than this they are extremely variable in appearance ranging from 50 to 250mm in height, lateral sepals are from 10 to 35mm in length and stem leaves can be 8 to 20mm in length.

Moving towards the granite outcrop we also find a small donkey orchid. This one is much duller than the ones found on previous days. From this it would appear to be the Western wheatbelt donkey orchid (Diuris brachyscapa) which flowers from July to September in locations east of the Albany highway from York down to Tenterden then east to Ravensthorpe. Florabase records the Narembeen shire as one such location.

Then nearby a splash of blue catches our eye. On closer inspection it is a Blue beard (Pheladenia deformis) which is a common orchid found from the Murchison River to Israelite Bay, as well as all the other southern states of Australia. They were originally classified as Caladenia back in 1810, then placed in Pheladenia in 2001.

Another orchid was found in the company of a snail orchid. The Sugar orchid (Ericksonella saccharata) is another common inland orchid, being found from Paynes Find to Israelite Bay. It is a distinctive white flowering orchid with purple lined labellum lobes.

Then just before we reach the granite another type of orchid is found. The Ant orchid (Caladenia roei) is one of the most regularly encountered orchids of the Wheatbelt. It flowers from Eurardy Station to Ravensthorpe during the months August to October. Named in honour of John Septimus Roe, the first surveyor general of WA in 1873.

Upon reaching the granite outcrop, we slowly ascent and find another donkey orchid growing in the vegetated sections of the rock. The bright Yellow granite donkey orchid (Diuris hazeliae) is found again which is not surprising as they range from Paynes Find to Salmon Gums over the months of August and September. It is great to find 2 species of Diuris in the one location.

I get caught up taking lots of photos and Deb gets to scout ahead. She calls out that she has found loads of Little laughing leek orchids (Prasophylum gracile) of both colour variations. So over I trot to grab some photos and there is Deb laying down getting her own shots. These little guys are very widespread and flower over a 4 mth season.
