Pseiidobiilbis ovalis compressis diphvMis , foliis lanceolalis aculis 

 brevibus, scapo gracili apice racemoso 3 — 6!loro, sepalis lineari-lariceo- 

 latis, pelalis paulo latioribus, labello cunealo emarginato basi auriculato 

 lamellis duabus linearibus crislalo, columnae alis oblongis inlegris.

Tlie scape of tliis spccies is about a foot liigh . wiib from 3 — 6 ratber small 

 llowers ai ilie end. Thc leaves are noi more iban 2 iriches long, an«l ihe pseudo-

0. scapo paucifloro foliis gramineis longiore , sepalis lateralibus 



parvis unguiculatis concavis , labello obovalo reduplicalo emarginalo, 



crisiae papillis liberis anterioribus brevioribus dorsali roslrato elongato. 



I bavc only seen a skelch of this, whicb seems to be quite dilTerent from all tbe 



oiber known Drazilian .species. Iis lip is largc and yellow. Tbe sepals and petals 



are verj small, and brownisb groen, spotled.

A furiher comparison of ibese planis has convinced me, that ihey are all forms 

 of one species, which. like 0. maculatum , assumes dillereni forms , actording as it 

 is inlUienced by localiiy or ollier causes. Tbe long slender graceful raceme or pa- 

 nicle, and ibe broad obovate or reniform yellow lip, dislinguish it readily from ihat 

 species.

Mucli like C. maculaium , but dilfers in ibe form of its lip, ils very narrow lcave

Bot. Reg. X.XVIL Misc. 180. (1841): This plani, which resembles C. maculatum in 

 liabil, but has a yellow lip . ihe form of which is ihat of a wedge , with rounded 

 aiigles, has llowered wiih Loddiges, wbo imported it from Oaxaca (1265). ^early 

 allied 10 Cyriochilum filipes. but differs in ihc form of the lip.
