Like S. Arachnites. I can distinguish it only by the very different flower 

 and form of the lip ; and for these characters I am indebted to a copy of a drawing 

 in the Peradeniya Bot. Giirden. The leaves vary from 2-7 by -J-l in., obtuse or un- 

 equally jiotched ; the peduncle from 1-3 in., and the raceme from 1-5 in. ; capsule 

 2-2i in., linear, straight ; poUinia 4 in unequal pairs narrow, quite distinct, and without 

 strap or gland in the figure. — There is a specimen of this in Herb. Bottler, without 

 habitat, named Mpidendrum complanatum, Eetz. Obs. vi. 50. 



32. S. brachystachys,-Hboft./. ; steni rigid, sheaths ^ in. strongly 

 ribbed when dry, leaves oblong, peduncle with the few-fld. raceme much 

 shorter than the leaves, sepals oblong and obovate-oblong petals obtuse, 

 side lobes of sessile lip falcate incurved, midlobe as long fleshy oblong, 

 spur scrotiform.

Stem as thick as a goose-quill. " Leaves ,24-3 by |-1 in., obtuse, notched. 

 Peduncles at every node with the raceme 1 in., very stout, rigid ; bracts 3-4, J in. 

 long, rounded ; sepals and petals about 1 in. long, keel narrowly winged ; column 

 very short ; anther low, not beaked. 



33. S. pauciflorus, ^00^./. ; stem rigid, leaves rather distant ob- 

 long obtuse, peduncle much shorter than the leaves 2-3-fld., sepals oblong- 

 lanceolate acute, petals nearly as large obovate-oblong obtuse, lip stipitate.
