Treniophylla are so difficult to describe from dried specimens 
that I make no apology for re-describing this from living 
plants. It is not easy to compare it with any other of the 
small genus, as most of the species are but indifferently 
described. I have never seen any leaves on the plant.

I have only seen one plant of this, which is very distinct in 
its very short stem, slender elongate scape, and connate 
perianth of a red colour. 
CLEISOSTOMA, Blume. 
This genus is usually distinguished from Saccolabium by the 
presence of a callus within the spur, and from Sarcanthus by 
the absence of the septum, which in that genus divides the 
spur more or less in two. It has several times been proposed 
to merge both genera into Saccolabiwm, especially as the calli 
are often difficult to make out in dried specimens. I should 
be inclined to retain both genera, although they are certainly 
very closely allied to Saccolabium. The septum in Sarcanthus 18 
evidently the well-developed longitudinal central ridge of which 
traces can be seen in most of the genera of Sarcanthew and in
