O. anguslalum Lindl. Orchid. Linden Nr. 90, 



Wild in Venczuela; in ihe thick forc^^is in the neighbourhood of Merida , at ihe 

 height of 6500 feet— Linden, 661. ^ 



,,A raagnificent cpiphyie. Pseiidnbnlbs oval , compressed; steni three or four feet 

 high, covered with innumbrable lluwcrs of a brillianl white. Petals rosy-purple ai ihe 

 base. Lip purple.'* — Linden. The panicle of this plant is very stilT and excessively 

 branched in an angular straggling manner. In the general form of the parts ii much 

 resembles 0. angnstatum , to which I formerly referred it; but a more accurate 

 examinaiion shovrs ihat it is essentially difTcrcftt, ihe lip being cordaie, not narrowed 

 10 ihe base, and the crcst downy all over wiih a different arrangement and form of 

 the lobes. 



I am unacquainted wiih the variety heterosepalum, mentioned by Mr. neichenbach 

 in the ..Linnaca" ; Nr. 1242. of Funck and Schlim's collection not having reached me.
