The flowers of this plant much resemble those of B.fusiformis, 

 Lindley, Bendrobium fusiforme, Tliouars, two flowers of which, 

 from Thouars's collection, I have seen in the Herbarium of the 

 British Museum, but the habit of the plant is quite different. 

 There are two sheathing- leaves on the scape, of which the lower 

 one almost invariably reaches to the base of the panicle and is 

 about 3£ to 4 inches long, striate, and winged on both sides for 

 its whole length ; the other is very much shorter, being partially 

 overlapped by the lower one. The whole plant dries black. 



There is a figure of what appears to be this plant in Deans 

 Cowan's drawings, the sepals and petals and base of the lip of 

 which are cinnamon, the apex of the lip rose-colour.

 lobis lateralibus brevibus obtusis, medio brevi oblongo integro ;

This plant resembles P. luteola in its general habit, but is 

 distinguished by its simpler inflorescence, rarely branched, more 

 numerous and shorter leaf-sheaths on the stem, broader dorsal 

 sepal, and colour. 



The whole plant is half a foot high ; the leaves 4 inches long, 

 half an inch in diameter. The bracts are 1 line long, the pedicel 

 9 lines. The whole of the flower is rose-pink, with a darker spot 

 in the centre of the lip. 



P. virescens, n. sp.— Semipedalis, caule basi tumido ; foliis 

 ovatis obtusis 2, inferiore minore ; racemo laxo basi paullo ramoso,

 petalis angustis linearibus rectis ; labello trilobo, lobis lateralibus 

 brevibus ovatis obtusis, lobo medio oblongo obtuso.
