 I.H. 17:21. Var. Dayanum, Reichb. This is colored 

 like the type, but the lip is rhomboid, apiculate, ser- 

 rate, and the teeth of the crests on the labellum 

 cross each other like the bristles on the nearly closed 

 leaf of Diomea muscipula. 



26. cordatum, Lindl. Pseudobulbs oblong, 1-lvd.: Ivs. 

 oblong, acute, 6-8 in. long: fls. large and handsome,

 blotched with brown ; hrbellum cordate, acuminate, 

 subcrenate, white, with a purplish crest at base and 

 spotted with brown on the limb; sepals lance-linear, 

 acuminate ; petals broader and longer, undulate. Mexico.

 England in a living state. It is free-flowering, but not 

 as good as plants subsequently introduced. Var. album, 

 Hort. Like the type, but labellum pure white instead of 

 wine-red; sepals and petals brown. I.H. 19:91. 



Var. splendens, Ch. Lem. Labellum rose-lilac; other 

 segments spotted. Seems to be like the type, with more 

 pronounced color. I.H. 12:449.

 handsome, varied with pale green, purple and white,
