THE AUSTRALIAN NATURALIST. 167 
Ill. Chiloglottis Gxnnii, Lindl. My specimens are from 
Bunninyong, Victoria; Hobart, Upper Derwent, and Launceston, 
Tasmania. This quaint and attractive little orchid, with its com- 
paratively large flower, out of all proportion to the size of the 
plant, is very common in Tasmania, mainly on the slopes of 
hills. The flowering time extends from September almost to 
Christmas. The colour varies from pale green in the early forms 
to very dark red-brown in the later. The flowering stem is 
rarely more than an inch or two in length until fertilisation is 
effected, when it may grow up to a height of 8 or 10 inches. 
This is not a constant characteristic: i.e., the stem may remain 
quite short; but it frequently does grow out. It is not a merely 
local freak, for it occurs in, Victoria as in Tasmania. This 
curious habit is shared by a species of Corysanthes (see below), 
and is probably an effort to ensure the scattering of the seed. 
On a hill-side near the Punchbowl, on the outskirts of Launces- 
ton, is a large patch of this species with many plants bearing 
two flowers. 
IV. Corysanthes. I confess that the members of this genus 
have a special fascination for me. Most collectors bewail the 
impossibility of drying and pressing them satisfactorily, but 
with patience and care it can be done, and they do not lose their 
colour as so many orchids do. I have specimens of the follow- 
ing species:—C. unginculata, R.Br., from Lindisfarne, Tas.; C. 
fimbriata, R.Br., from Low Head, Tas.; C. primosa, R. Cunn., 
from Lane Cove River and Bulahdelah, N.S.W.; Warrnambool, 
Viec.; Derwent and Tamar Rivers, Tas.; C. bicalcarata, R.Br., 
from Bulahdelah, N.S.W. and Haglehawk Neck, Tas.; C. dic- 
menica, Lindl., from Derwent and Tamar Rivers, Tas. There ap- 
pears to be some difficulty in distinguishing the various forms. 
C. primosa, C. fimbriata, and C. diemenica are regarded in some 
quarters as merely varieties of one species. Near Low Head, at 
the mouth of the Tamar River in Tasmania, in 1922, I found all 
three markedly distinct from each other. The following descrip- 
tions are compiled from notes made on the spot. 
C. fimbriata—Flowering June and early July, usually in 
damp, well-shaded places amongst bracken fern. “Hood” (dorsal 
sepal) pointed, sharply toothed, purple, densely spotted with 
darker purple. Labellum very dark purple from the throat out- 
wards, especially along the middle portion, from which rows of 
spots of the same dark colour extend to the margin, which is 
strikingly fringed all round except at the base. Flower opening 
very wide, from half to over one inch in length from point of 
hood to end of labellum. Leaf strongly veined.
