Flowers as large as in 0. maculosum, golden yellow, except the side of themiddlo 

 lobe of ihe lip and ihe points of ihe crest. Raceme with from eight to twelve 

 flowers. According to Rchb. fll. the bracts are very large and glumaceous , as long 

 as the slalked ovaries; lower sepal with two acule lobes. Petals somewhat blunt. 

 Lip scarcely unguiculate , rounded on either side, narrow, auriculate, then ligulate. 

 Crest narrow. ihree-ioothed in front, the laieral teelh turned oulwards and prostrate. 

 Ihat in ihe middle a keel. Column long , wiih three-lobed column-wings . the upper 

 lobe being ligulate, the lower oblong and crenulate. This exactly agrees with a 

 flower given me by Prof. Reichenbach. 



Wild in Cosia Rica and Veragoa . on Oaks at 8 — 10.000 ft. — Warscewicz. The 

 thermomeier stood at 41° Fahr. in November, and ihe plant perishes as soon as it 

 descends into the warm zone. — Rchb.
