We head NE of Esperance today to see if we can find the elusive Hare orchid, which we did not locate in March. At our usual spot on Wittenoom Road we pull over and check around. First up we find another of the White bunny orchids. This time we have located the Crinkle-leafed bunny orchid (Eriochilus dilatatus subsp. undulatus).
As the name suggests the leaf has undulated margins. This orchid is located from Northampton to east of Esperance and can grow to 250mm in height.
Further into our search the elusive Hare orchid (Leporella fimbriata) turned up. So happy that we have now found the quartet of species for the start of the season in the Esperance area.
Leporella is a monotypic genus which is found from southern Victoria to Western Australia. In WA the Hare orchids are found from north of Kalbarri to Israelite Bay.
Today we head to another regular location to the east of Esperance; Coolinup Road which has increased in size due to previous explorations. Today we decide to check on the location we discovered last season.
Along the track in we are eagle eyed for orchids, however none were found before we reached the granite rock clearing. In the clearing we found many white bunny orchids that had finished flowering. Luckily there were still some in bloom.
The White bunny orchid (Eriochilus dilatatus subsp. dilatatus) is found growing in the moss under the protection of a hakea bush in the shallow soil on the granite rocks.
These orchids are found between Dirk Hartog Island and Israelite Bay during the months of March, April and May and can grow to 350mm in height.
Many other White bunny orchids are found before Deb comes across a small drove of Hare orchids. Only one of which is in flower. Each orchid may have up to 3 flowers with pairs fairly common.
Today I visit Dempster Head which is a shire reserve that overlooks Esperance Bay and First and West beaches. (Mud Map SE 34). First up I located some White bunny orchids growing alongside the track below the water tanks.
The size and shape of their leaves attest to my identification. With a length of 40 to 100mm and width of 5 to 18mm, the leaf of the White bunny orchid is by far the largest of the bunny orchids growing in the Esperance area.
Later on the granite rocks above Lovers Beach another small bunny orchid is found growing in the moss and lichen.
The Granite bunny orchid (Eriochilus pulchellus) as the name suggests is found growing in shallow soil pockets on granite outcrops from Esperance to Balladonia and Northcliffe to Bremer Bay, with a disjunct population in the Darling Scarp.
The flowering season is over April and May with plants producing up to 10 flowers. It has a short stature of up to 150mm and produces a small smooth leaf only 5 to 15mm in length and 3 to 8mm in width.
Very happy to have found during the month of April, the 3 bunny orchid types, that flower in the Esperance area.
