..Flowers smooth, inlcrnally yellow, e.xternally purple. — Caudicuhie two . glandula 

 transverse , crescent-shaped. Pollenmasses iwo , each of which is divided into two 

 distinct parts. This species posscsses a creoping rhizoma , pp. Iii size and form 

 th^^e flowers nearly reseinble these of barbata , but are soiitary and of a di/Terent co- 

 lour. Maxillaria aureofulva, barbata, and purpurascens possess double candiculae (as is 

 the case also in the genus Difrenaria) and their innorescence in other respects differs 

 so much from that of any otber species of Maxillaria wilh which I am acquainted, 

 that they may be considered as forming a very disiinct group of the genus". Fred. 

 Westcou. Iniroduced for ihe Birmingham Hort. Soc. by W. Fry Esq. 1840. The 

 plant I have not seen and do not recognize.
