Cogniaux regards 0. monorrhiza Sw. as distinct from H. maculosa Lindl. 

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

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

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

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

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