 iaxse, pyramidatae, vix folia suprema excedeutes, ramulis divaricatis, 

 Bradece ad ramificationes parvse, lineares. Fedicelli ultimi 1-3 lin. 

 lougi. Calyx minimus, segmentis acutis. Corolla vix linea longior,

 A single plant of this was found by Mr, Spruce by the side of an 



igarape, deep in the forest near Panure, in September, 1852.

 In moist caatingas near Panure, October, 1852. (E. Spruce, n.

VOYRIELLA, Miq. 



Of this little plant Mr. Spruce found three or four specimens, widely 

 apart from each other, in the woods of the Rio Uaupcs, They differ 

 from each other in the length, both absolute and relative, of the cap- 

 sule and calyx, and unfortunately I cannot find a single corolla amongst 

 them to examine. The stigmate, as it remains after the fall of the co- 

 rolla, is in these, as well as in a specimen from Miquel of his F, parvi- 

 fora, very shortly bilamellate at the end of a style of some length. 

 The genus appears to be very distinct from Voyria, but very nearly 



allied to Schuebleria,

 This genus affords one of many instances of the danger of gene-
