Indico, et v. ic. pict.) 
Flores straminei, intüs guttati, expansi 3 uncias lati: labellum cum basi 
dilatata column: articulatum; lamellis tribus in medio, quarum inter- 
media abbreviata; lobo intermedio atropurpureo. Ovarium fere tres 
uncias longum, bracteá ad basin solitarià ovatà. Pedunculus vix unciam 
excedens bracteis 2 magnis foliaceis albis ex basi ortis tectus. 
This beautiful species approaches nearer to the genus Bolbophyllum 
than any with which I am acquainted. Its flowers are not exactly those 
of Dendrobium, the labellum being shaped differently from what is usual 
in that genus. It is however comprehended within the definition I have 
given of it, and will by no means enter Bolbophyllum with which it is its 
habit chiefly that accords.

This curious species has the habit of the next division, but is covered 
With clavate spurious bulbs, from the apex of which springs a solitary ob- 
long leaf, producing from its axilla 2 or 3 snow-white flowers. I only know 
the latter from Mr. Macrae's drawings.
