The plant belongs to the group of mostly very indifferent looking 

 species which are more or less similar to B. neilgherrense Wight and B. 

 Careyanum Spreng. All have long creeping rhizomes, rather distant 

 monophyllous bulbs, nodding more or less capitate spikes and most of them 

 or all reddish flowers. The chief-character of this species consists in the 

 three-pointed petals, a peculiarity not observed in any other species of the 

 group. The lip in its shape does not differ very much from that of the 

 allied species , but here the side-lobes are reduced to a thin transparent 

 border whilst the middle-lobe consists of the strong fleshy body so common 

 in Bolbophyllums.

10. E. semiconnata Krzl. n. sp. 



Bulbis nummiformibus applanatis orbicularibus 8 — 10 mm. diam. 

 margine subrepandis supra retinerviis, foliis sub anthesi nullis, mihi 

 non visis, floribus* semper unicis brevi-pedicellatis , bractea ovata 

 cucullata acuta quam ovarium longiore, tlore nutante. Sepalo dor- 

 sali obovato-oblongo brevi-acutato, sepalis lateralibus in unum basi 

 gibbosum connatis apicern versus liberis acutis cum dorsali conglu- 

 tinatis non connatis, petalis obovatis obtusis, tota superficie minute 

 crystallino-glandulosa, labello simplice ovato acuto basi plicato ibique 

 umbonato; gynostemio perbrevi. — Flores extus et intus glabri, in- 

 tense rubri, sepala 5 — 6 mm, longa, labellum 2 mm. longum. 



This curious little thing is the sixth species of the Porpax-group and 

 is closely allied to E. ustulata Par. & Rchb. f. The differences are how- 

 ever considerable enough to keep the plant distinct from E. ustulata. The 

 flowers of the latter are pubescent on the outside, those of our species 

 are quite glabrous, the upper sepal is triangular and acuminate in E. ustu-
