the very acute apex is sharply reflexed so that it is not 
at first apparent. The lip is commonly trilobed but is 
almost entire in a few species; the spur has a narrow 
mouth, but is rather variable otherwise. The rather short 
acute rostellum projects forward or slightly downward ; 
it is apparently variously cleft after the removal of the 
viscidia. It should be pointed out, however, that the 
flowers are rather small and the state of preservation of 
some of the species is not good enough to be certain of 
the exact details of the rostellar structure. 
As aresult of my investigations I now place the total 
number of recognised species at 14, of which three are 
newly described later in this paper. Since several of the 
species are very small plants it seems probable that there 
may yet be further similar species awaiting discovery ; 
some of the mainland species have been gathered only 
in the past 20 years or so. 
The affinity of Angraecopsis appears to be with Mys- 
tacidiwm, from which it differs in the unequal sepals, the 
characteristic petals, the normally 8-lobed lip, the nar- 
row mouth to the spur and the side lobes of the rostel- 
lum not being papillose or pubescent.
