Sepala lierbacea, patentia ; laleralibus pedi producto columnae ad- 



natis; pelala conformia, labellum indivisum, planum, cum pede colum- 



nae arliculalum ; linea mediana elevata, lamella intramarginali digitata. 



Columna brevis , semiteres, mutica, pede longo lineari. Stigma circu- 



lare. Pollinia 2, solida in caudiculam ovalem sessilia ; glandula?. — Herba 



epiphyta, Guayanensis, muscicola, acaulis. Folia membranacea, nervosa. 



Pedunculi fililormes, pauciflori, parce vaeinati. Flores parvi, herbacei. 



The adhesion of tlie Interal sepals to the exlended foot of the columr, , the spur- 



less lip. aml other characiers seem to refer this to the Maxillarideous herd , as well 



as ihe steraless bulhless habit. Its tnie station would seem to be near my Zygope- 



talum gramineum, which is by no means ihe plant so called hy Mr. H. G. Reichen- 



bach, and those Warreas which form ihe same aulhor's genus Warcziewiczella. But 



the solid undivided polien-masses, peculiar lip and habit, are essentially different. 



1. CHEIRADEMA CUSPIDATA Lindl. 



A stemless bulbess plant, froni three to four inches high. Leaves a few, radical, 

 obovate, membranous , sliglitly rilibed, spreading, drawn to a fine slender recurved 

 point. Peduncle llliform , with two or three spreading disiaat acuminate vaginae, 

 bearing one to three drooping flowers at the point. Sepals and pelals ovate , acute, 

 Lip raembranous, obovate , very obscurely three-Iobed, with an elevated line along 

 the middle, and a thin intramarginal lamina, divided into flve equidistant teeth. There 

 arejno flowers upon my specimens of Leprieur's 114, but I think it is the snme as 108, 

 which I have examined. My thanks are due for both lo the Adminislration of the 

 Museum of Natural History at Paris. 



Wild in French-Guyana.
