MALAXIDEJE. DENDROBIEX. 61 
1. Microce ia exilis. 
Hab. in Madagascar supra arborum ramulos; Forbes. (hab. s. sp. Soc. 
Hortic. benign? commun.) 
Sepala ovata, obtusa. Calcar ad os constrictum. Pollinia depressa, ro- 
tunda, versus medium foveà magis pellucida, quasi reniformia apicibus 
approximatis. 
For my specimens of this very curious little plant I am indebted to the 
Horticultural Society, who received it from Mr. Forbes. It has the smallest 
flowers of any Orchideous plant I know ; it grows upon the young branches 
of trees covering them with its numerous thread like roots. It appears to 
be leafless. 
I suspect that Angraecum aphyllum of Du Petit Thouars, t. 73. belongs 
to this genus.

Sepala ringentia, inzequalia, lateralibus a supremo valde distantibus, inter- 
vallo denticulato, basi invicem et cum pede columnz connatis intus 
barbatis, Petala O0. Labellum cum pede columne articulatum, incum- 
bens, ovatum, trilobum, lamellis 4 parallelis in disco, lobis lateralibus 
antrorsüm falcatis apice bidentatis. Columna basi longé producta, semi-

Note. This is the only known genus of Orchidez in which the petals 
are abortive. Nothing is found in their room, but there is a wide tooth- 
letted interval between the upper and lower sepals.
