The discovery of this species would also appear to be due to 
Ruiz and Pavon. It appears to be very frequent in S. Mexico, 
near Zacuapan, Mirador, Talea, San Pedro Nolasco, Oaxaca. 
We have had specimens from Galeotti (5284, 5278), Schiede, 
Ehrenberg, Leibold, Jiirgensen, Botteri! It occurs also in 
Guatemala; Bernoulli! In Costa Rica; Oersted! Cartago ; 
Wendland! It occurs oftener in collections than amateurs could 
wish it. ‘They used to be frightened at what they call an ugly 
plant. 
Rhizome strong, creeping, sheathed, with strong white roots. 
Pseudobulbs pear-shaped or semifusiform. Leaves two, seldom 
one, oftener three, linear-ligulate or linear-acute, of the texture 
of parchment. Peduncle racemose, with a few sheaths downward, 
the upper part racemose, straight or flexuose. racts triangular, 
somewhat boat-shaped. ‘The stalked ovaries longer than the 
bracts. lowers straight, but often nodding in dried specimens. 
Sepals oblong, bluntly acute. Tepals often somewhat broader, 
but also narrower, or equal, ligulate-acute or hgulate-obovate, 
pale sulphur-coloured, subsequently deep ochre-coloured. Lip 
adnate to the base of the column, dilated semiovate, now cuneate, 
now nearly heart-shaped at its base, trifid; lateral lacinie trian- 
gular, with an acute or a straight angle; middle lacinia semi-
