08/10/2022 & 09/10/2022 ….. Jacup Jewels

Numerous days, Road Trip, Western Australian Orchids

Upon leaving the Jerramungup burnt are we head east looking for somewhere to park up for the night. We make it about 35kms when we pull into the Jacup Highway Park at the Fitzgerald River crossing. This will do, so we set up the camper and I do my best to drive over a log in my Ford Falcon, not the greatest idea 🙂 I’ve had.

Now we still have the late afternoon to go orchid hunting. As per our previous visit to this location, we are not disappointed. First, we find the Green spider/Fringed mantis orchid (Caladenia falcata) flowering in isolation and in small groups over the entire area we checked out.

As can be seen in the picture above the hybrid, Wheatbelt spider orchid (Caladenia x cala) was also found. It was amazing how many were actually found, as we usually find one or two only in each location.

And of course, we also found the other parent for the hybrid. The Stark white spider orchid (Caladenia longicauda subsp. eminens) occurs as far east as Ravensthorpe and grows in open woodlands so seems to fit the bill.

Next, we find the very special Lazy spider orchid (Caladenia multiclavia) which is recorded as occurring between Wongan Hills, Borden and Ravensthorpe. This unusual looking orchid is known for its upright petals and sepals plus the smooth striped labellum with a dense band of bristly headed calli.

We also come across a mixture of other orchids but not in great numbers, so I will record then with only 1 pic each. Firstly, there is the ever-reliable Cowslip orchid (Caladenia flava subsp. flava) and Common mignonette orchid (Microtis media subsp. media). Both are common, widespread orchids. Then the more rarely found, without a recent summer fire, Red Beaks (Pyrorchis nigricans) is discovered with a nine-flower inflorescence. Finally, a pale coloured Pink candy orchid (Caladenia hirta subsp. rosea) and possibly a Ravensthorpe rufous greenhood (Pterostylis leptochila) yet to fully flower are found.

One orchid not expected was the Common dragon orchid (Caladenia barbarossa) which is found flowering between Bindoon and Munglinup. There are only 4 species of dragon orchids, and all are endemic to WA. Only 2 specimens found but still very happy.

However, one final orchid is found in decent numbers. The Drooping spider orchid (Caladenia radialis), is found flowering between Northampton and Ravensthorpe from August to October. The labellum can have smooth margins or tiny marginal teeth.

Back to camp due to the fading light.

Small campfire lit

We awake to a beautiful sunny morning, have breakfast then decide we will take some time this morning to complete a search down to the river. Fingers crossed for something new.

First up though I will post pictures of those orchids we come across that we also found in our afternoon search yesterday.

Now for the new findings of the location. The Short-sepaled spider orchid (Caladenia brevisura) is found between Jerramungup and Israelite Bay from August to October. Only one specimen found, and not the best picture, but a record non the less. Another sole specimen found was that of the Bee orchid (Diuris laxiflora) which flowers September to early November between Gingin and Esperance.

Blue sun orchids are found in good numbers closer to the river. Now identifying them is needed. As I am writing this account over 12mth later I am identifying them from pictures taken. Based on these I feel some to be Scented sun orchid (Thelymitra macrophylla) due to the broad leaf and large numerous flowers. Others though have thin leaves with fewer flowers, so are most likely the Shy sun orchid (Thelymitra graminea). Both are recorded as flowering in the Shires of Ravensthorpe and Jerramungup during the month of October.

It is 11am so we had better push on as we need to arrive home in Esperance today. One last stop is made at Kukenarup Memorial, where we enjoy a spot of lunch before one last exploration for orchids.

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.

12/09/2021 ….. Jerramungup to Munglinup

East Naernup NR, Koornong NR, Nature Reserves, Numerous days, Road Trip, Western Australian Orchids

After an early breakfast we head out to our first location to continue our orchid hunt. Some of the first orchids found are still covered in dew, which exposes the cobwebs as well.

JERRAMUNGUP CEMETERY

Well, I glad we persevered at this location given we found nothing in the first 5 minutes. The hybrid found was our first with a Dragon orchid and the numbers of white spiders was amazing.

However, we must keep moving but we only make it some way up the SouthCoast Highway before pulling into Jacup Highway Park, a rest stop near to the Fitzgerald River crossing. Seems a bit overrun with weeds, but we make the effort and are rewarded big time.

JACUP HIGHWAY PARK

After some amazing finds, we jump back into the Triton and head east. We decide to check out another new location and pull over at Koornong Nature Reserve. Some of our finds may be outside the Nature Reserve boundary as the scrubland extends further along the roadside than we were originally aware of.

Koornong Nature Reserve

Four species found, so not too bad a spot. Worthy of a re-visit another time. Next stop is further along the highway. Here we pull into an old bitumen dump and venture into the surrounding scrub. Orchids found 🙂

East Naernup Nature Reserve

It is now way past lunch time, so we head to Munglinup Roadhouse for their amazing burger. Near the roadhouse I find a nice spider orchid and take a photo, which ends up being the last taken for the day.

Our 2021 orchid hunting road trip has come to an end as we head home from Munglinup. As usual it has been amazing to find so many beautiful orchids in the wonderful West Australian bush and woodlands. Many old favourites found as well as some new species, which is always very exciting. Quite a few hybrids found this time as well as a few lutea or polychromic variants.
