 ovate-lanceolate, acute or shortly acuminate, about as long as the ovary, 

 1*2-2 -2 cm. 1., 4-5 mm. br. Pedicels very short. Flowers white. Sepals

 8-9 mm. 1., barely -5 mm. br. Spur pendulous or curved anteriorly, 

 filiform, apex acute, 1-5-2 cm. 1. Stigmatic processes short, fleshy; 

 anther-canals much longer, ascending ; rostellum small, triangular. 



Cogniaux regards O. monorrhiza Sw. as distinct from H. maculosa Lindl. 

 and identical with H. alata Hook., and describes the lip as undivided, 

 Swartz, however, says "labio tripartite" Prodr. & "Labium ad basin fere 

 tripartitum" Flor., in which H. maculosa agrees, but H. alata differs. 



3. H. repens Nutt. Gen. Amer. ii. 190 (1818) ; stem 

 creeping at base ; leaves 3-nerved, oblong-lanceolate ; lip with 

 lateral lobes pendulous, shorter than sepals. — Lindl. op. cit. 310;
