2. COMPaRETTIA COCCINEA Lindl. Bot. Reg. XXIV. (1838.) 68: 



Foliis angustis, coriaceis apice obliquis acutis, sepalo antico aculo 



calcare falcalo duplo breviore , labello obcordato subrepando basi bila- 



mellalo calcaribus subulatis cilialis, columna medio sub stigmale elevata. 



This beauiiful and very rare epiphyle flowered with Loddiges and is said to be 



a native of Brazil; it however agrees so entirely wiih dried specimens collected near 



Xalapa and now belore me , tbat some mistake is to be suspected in iis reputed 



country. 



Perigonium flavo rubrum, labellum scarlalinura ; folia snbtus violacea. 

 Comparettia consists at present of this and two oiher species inhabiling Peru. Of 

 ihese C. laicata approaches ihe present subject in many respecis. It, however, appears 

 to differ in baving broader leaves, larger llowers, no elevated plate at the base of ihe 

 stigma and tbe spurs of tbe lip smootb. Struct. of labelium and sepals as in Aco- 

 nitum.
