and characters 



Myanthus.

Sepala libera, sequalia, lateralibus paululikm 

 Petala conformia, angustiora, sepalo supremo supposita. 

 Labellum planum, obovatum, 3-dentatum, sepalis brevius. Columna erecta, 

 teres, basi bicirrhosa, postic& ad cardinem antherse long& producta. Anthera

1. Myanth 



Found 



trees in the 



bourhood of Rio Janeiro. The racemes are cernuous, and 



about a foot long, or more 



The flowers have a greenish 



ground, closely covered with rich reddish brown 

 Perhaps Catasetum cristatum would be better 



yellow 



spots. - 



referred to this genu 



MONACHANTHUS. 



Perianthium explanatum. Sepala et petala eequalia, deorsim versa. 

 Labellum posticum, carnosum, indivisum, ventricosum, sepalis multo majus. 



Columna brevis, crassa, mutica. Anthera .... Pollinia — -Epiphyta, 



Cataseti habitu. 



1. Monachanthus viridis. Found on trees in the Cor- 

 covado. 



The fleshy stems are 



tly those of Catasetum, as 



pt that they are shorter 



In the draw 

 „g we have examined, the flowers are represented in pairs 

 from the apex of an erect scape about 9 inches high : they 

 are fleshy, and of a deep uniform green, with a labellum 

 that looks something like a hood drawn over a little face 

 represented by the column. 



This genus differs from Catasetum in the want of cirrhi 

 upon its short column, and in the expanded perianthium, 



the five segments of which are turned all one way, like those 

 ofEulophia.
