the stem near the base of the pseudo-bulb, leafless erect sub- 

 falcate, 8-15 cm. long, rachis dilated and fiat in the upper part, 

 4-30-fiowered, the flowers racemose upon each face, bracts 

 deltoid; side sepals ovate-lanceolate falcate acute, concave at 

 base, scabrid on the upper surface, about 6 mill, long; odd sepal 

 linear sub-obtuse, nearly twice as long as the lateral ; petals 

 linear falcately spreading or reflexed, a little shorter than the 

 side sepals ; lip fleshy, square thick and keeled at the base, then 

 suddenly contracted into a sub-obtuse tooth-like pendulous point, 

 the whole scarcely 2*o mill, long ; column short, widely winged, 

 the wings terminating in a short tooth on either side at the 

 summit ; capsule oblong, 1-15 cm. long. 



Described from several living and dried specimens. Colour of 

 the flowers dull red-purple, the petals usually paler or reddish- 

 orange. From a drawing which I have seen by the late Mr. 

 John Sanderson, the colour is probably somewhat variable. I 

 have examined the specimens in the Kew herbarium marked 

 Megaclinium Sandersoni, and the type of M. scaheridmn, and 

 compared them with Mr. Culver's specimens from Barberton 

 here described, and incline to regard them all as forms of one 

 variable species. This plant is interesting to South African 

 students as being the only one of a somewhat large genus which 

 straggles beyond the tropic so far south. The section Megacli- 

 nium to which our plant belongs is held by some botanists as a 

 good genus ; the difference from Bulbophyllum consists almost 

 exclusively in the flattened and enlarged rachis of the inflores- 

 cence. The remaining members of this section are all, with one 

 exception, inhabitants of tropical Africa. The genus Bulbo- 

 phyllum as a whole, is, however, spread over the tropical regions 

 throughout the globe.
