A small tufted plant, with a usually short stem and a moderate 

 number of leaves, generally lanceolate, 2~3| inches long, by £-£ 

 across, sometimes shorter and broader, 1| inch long by f, and 

 a number of rather long white roots. The racemes are slender, 

 zigzag, and few-flowered, from one to three on a plant ; they 

 rise from the axils of one or more of the lowest leaves. The 

 flowers, from two to five on a raceme, are white, 2 or 3 lines 

 across. The spur is short, rather thick, and club-shaped, with 

 the apex turned up. The capsule is elliptical, | an inch long, 

 rather large in proportion to the size of the flower. 



A. multiflorum, Thouars, t. 74, seems, as Moore (I. c.) has classed 

 it, to be a luxuriant variety of this species.
