pals and petals, and a broad yellow middle lobe of the lip. Upper 

 sepal deltoid-ovate, recurved, with a short broad claw ; lateral 

 sepals parallel and deflex.ed, much longer than the upper, 

 with long claws that expand into an obovate-cuneate limb 

 recurved at the lip. Petals ovate-lanceolate, with broad 

 claws, recurved, as long as but narrower than the dorsal sepal. 

 Lip about half as large as the petals, recurved and almost 

 revolute ; lateral wings small, hatchet- shaped, serrate on one 

 margin, sharply recurved ; midlobe paddle-shaped, consisting 

 of a long flat claw and transversely oblong limb one-third of 

 an inch across, which is turned completely back and thus 

 hidden ; base of the lip with various crests and tubercles, 

 which are confluent with those of the base of the column, and 

 two small lateral auricles. Column short, with two small 

 cuneate fleshy spreading wings, and two flattened subulate 

 or decurved horns in front. — /. L. H.
