gree of certainty he separated when sterile. The habits, 
psendo-bulbs, and foliage are practically identical. AVhen 
in flower, however, they separate qnite readily. The dif- 
ferences are, individnally, minor ones but in the aggregate 
the define the species ade(iiiately. E, Unariiflora has easily 
the largest flowers and is the only white one. It and E. 
fitzalani have keeled plates, the former having two keels 
and the latter three with two prominent calli on the mid- 
lobe. The labellum of E. lipawides is quite different from 
that of E. jiornata. The latter has lateral lobes made quite 
distinct by deep clefts in the lamina of the labellum; in 
E. liparoides there are no such clefts and the anterior 
margins of the lateral lobes curve outwards and down- 
wards to the mid-lobe in the manner of some species of 
JAparis. It is to this feature that the specific name refers. 
These two species can also be readily separated by the 
relative lengths of their colunui feet. In E. inornaia the 
foot is twice as long as the column and in E. liparoidei^ 
it is the same length.

A RECORD OF TPICTIOPELTULA SP.

While examining speeiments epiphyllous algae from 
South Queensland rain forests the author came across 
numerous specimens which could be referred to one' of the 
atrichous forms of what Jennings (189(i) described from 
New Zealand as '' Phyeopclfis niyraA' This species is now 
recognised' as being a fungus, not an alga, and Jennings’ 
name has been discarded by Santesson (1944). A speci- 
men of the Queensland plant has been determined by Dr. 
E. W. Mason of the Commonwealth Mycological Institute 
as Trichopeltida sp. 
The colonies appear as fine, black, irregularly branched 
lines on the upper leaf surface of a wide variety of rain 
forest species. They are typically band-like, up to 5 mm. 
or longer, the diameter generally irregular and within the 
one thallus varying from 30-150 u. The thallus is composed 
of a single layer of radiating rectangular cells 3.5-7 ,u long,
