view, — the last two variously magnified. — Note : figs. 1 and 2 are from 

 young and rather small flowers, and the spur has not yet become inflated. 



Erect, glabrous, 30-90 cm. high ; stem sparingly, or sometimes 

 densely, leafly ; leaves several, stiff, rather erect, or sometimes 

 few and lax, lanceolate, acute, strongly nerved, passing into 

 similar gradually smaller sheaths and bracts ; raceme oblong, 

 laxly many-fl., 5-6 cm. in diameter, flowers spreading, bracts 

 narrow lanceolate acuminate, shorter than the ovaries ; side 

 sepals obliquely ovate, obtuse apiculate reflexed, about 8 mill, 

 long ; odd sepal oblanceolate obtuse concave erect, equally long ; 

 petals bipartite nearly to the base, posterior segment linear 

 erect, as long as the odd sepal, anterior much shorter, broadly 

 ovate or nearly lanceolate obtuse, shortly clawed ; lip tripartite, 

 segments linear, the intermediate about 8-9 mill, long, the 

 lateral broader, shorter and divaricately spreading, spur filiform 

 inflated towards the apex, somewhat longer than the pedicel and 

 ovary; clinandrium short ovate concave erect; rostellum closely 

 set within its fold, erect subulate acuminate, produced at base 

 into two nearly straight projecting arms ; stigmatic processes 

 club-shaped, projecting, about as long as the rostellary arms ; 

 ovary with pedicel curved, 2 '5-3 cm. long. 



Described from 2 living, and several dried specimens. The 

 flowers are light green and fragrant. The species is widely 

 distributed and tolerably easy to distinguish. The petals vary a 

 little in the relative breadth and length of their segments.
