spathulate. jietals slightly narrower, lateral sepal and 
petals more or less falcate, all segments incurved, lateral 
sepals attached to the very short column-foot to form a 
small mentum ; labellum sessile but mobile on the very 
short column-foot; lateral lobes relatively large, erect, 
triangular: mid-lobe absent; sac with a long finger-like 
callus projecting upwards from the base of the anterior 
wall, spur bent forward. Column short, broad, bent 
forward; anther large, beaked, 2-celled; pollen masses four 
in two groups one mass in each group larger than the 
other, the larger sub-globose, the smaller somewhat flatten- 
ed at the margin of contact, pedicel broad, caudicles 
thread-like and very elastic, the disc large, circular, 
generally projecting slightly between the rostellum and 
the beak of the anther. Rostellum forcipate. Stigma 
large, circular, deep, immediately below the rostellum, and, 
because of the bend in the column, facing almost down- 
wards into the sac. 
A fairly common epiphyte of the scrubs of Queens- 
land and northern New South Wales. 
DISCUSSION 
The plant was originally described by Mueller (1) as 
Saccolabium hillii and this diagnosis was followed by both 
rientbam (2) and Fitzgerald (M) until Bentham (4) later 
removed it to Ornithoclulus Wall, where it has since 
remained, although some later writei's have expressed the 
opinion that the transfer was not a happ\* one. Rupp (5) 
gave the most recent expression of this doubt when he 
said, “It is extremely doubtful whether the plant 
described below, which is found in this State and in 
Queensland, belongs to Ornithocliilns at all. Mueller, 
Bentham, and Fitzgerald placed it in !^accolaJ)ium, but 
Bentham subsequently removed it to Ornithochilus, where 
it must remain until its ])osition is finally* established.” 
In his paper (6) entitled “Breaking-up of the Genus 
Cleisostoma in Audralia^^ the same writer said, “It is 
generally accepted that the latter {(). hilUi) is not a true 
Ornithochihis. Dr. Rogers informed me that the late Dr. 
Schlechter intended to make it the type of a new genus, 
to be named FitzgeraldieUa, which is No. 524 in 
Schlechter 's “Systema Orchidacearum, ” 88, July, 1926; 
but no record of his transfer of the Australian plant is 
known.”’ The present writer is indebted to Mr. V. S. 
Summerhayes of Kev: for his recent corroboration of the 
fact that there is no evidence extant that the transfer of 
the Australian plant was ever effected.
