Planned family picnic cancelled, so we took the opportunity to go for a Sunday drive. Time to check the local area to see if we could find anything special. We headed west first, with a roadside stop producing only Caladenia leaves. We then pulled over for another roadside stop on the Gibson-Dalyup road, which proved more successful.
A donkey orchid catches my eye, then Deb notices I had walked past 2 plants to get to my find. Typical of me to miss ones that Deb then finds. Oh well, a find is a find. The orchid appears to be the Green Range donkey orchid (Diuris littoralis) which occurs between Denmark and Esperance and flowers from July to September. Leaves of other species located but nothing yet in flower or already past their time.
We now move on to Gibson to see it we find anything new. Once we reach the track off Walker Road we chug along in 1st whilst hanging out the window looking for anything. I spy a nice big Caladenia leaf so pull over to go for an explore. Before that though I make coffees from the thermos. Deb finds a couple of Banded greenhoods (Pterostylis vittata) which we found here on a previous visit, however took some photos to record it nevertheless. Another Pterostylis orchid found however not fully open. The Jug orchid (Pterostylis recurva) will be a common sight soon enough.
Slightly disappointed with our luck so far today, so we move on to our Crawford Road location. Again we appear to be too early as we find many orchid leaves, with some in bud. So where to go now? Helms Arboretum (Mud Map SE 35) of course. Surely we will find something in flower there.
We decide to mix it up and turn down a track in the arboretum we had not checked out before. This lead us nowhere that seemed likely to produce orchids so we found our way back to known territory. First up though, we head to a sunny spot to have lunch. Curried egg sandwiches eaten whilst checking out nearby spots. Deb finds so many budding spider orchids in a spot we had not really checked before, so we now know where to check out later in the season.
Moving on we head to the location where we have previously found Western tiny blue orchids. Deb drops me off to walk through the plot, whilst she drives around the boundary. I find some what I believe to be Banded greenhoods (Pterostylis vittata) however one of them is quite dark so am not so sure. Could be Dark banded greenhoods or Mallee Banded greenhoods. Thoughts welcome on the ID. No tiny blues found as they are listed as flowering from August, so again we must be too early.
Back on the main road into the arboretum Deb spies a small flowering spider orchid blowing in the strong winds. Very difficult conditions to try and get a good photo to assist with identification. I will provide two options. Either Western wispy spider orchid (Caladenia microchila) or Common spider orchid (Caladenia varians) as both flower early in July and extend into the Esperance area. What are your thoughts?
Then it was time to check out the plot where we find our king spider orchids. Deb as usual finds the first one in flower. The Esperance king spider orchid (Caladenia decora) as the name suggests is found around Esperance. It actually ranges between Bremer Bay and Cape Arid and inland to Scaddan. It is said to flower from August to October so the few orchids we found today must be some early bloomers.
We then move on to the plot where we find snail orchids in most years. This time is no exception. The snail orchids grow from quite a large rosette of leaves, have 2 or 3 stem leaves on a smooth stem and uniformly thick lateral sepals. I have been advised by a knowledgeable person from the WA Native Orchid Facebook group that they are most likely the yet unnamed Helms snail orchid (Pterostylis sp. ‘Helms’). Also found some spider orchids in bud.
It’s now 2 pm so we make tracks for home as Deb commences her shift at 4 pm. Was not expecting to find 2 species of Spider orchids in flower so it turned out to be a great Sunday exploration.
