The Frilled Oncid. 
GYNANDRIA MONANDRIA. 
Nat. ord. ORCHIDACEÆ. (Oncnips, Vegetable Kingdom, p. 173.) 
ONCIDIUM Swartz. 
Sect. Evoncıpıa, Heteranthia, tetrapetala, macropetala. 
C. amictum; pseudobulbis elongato-ovatis diphyllis, foliis oblongis perga- 
meneis basi angustatis, scapo (maculato) foliis longiore, paniculä 
racemosä densá multiflorà cernuà, sepalis lateralibus apice tantum 
liberis, labello obcuneato bilobo auriculis baseos ciliatis apice dilatatis, 
cristee tuberculis duobus maximis acutis divergentibus a fronte duobus 
posticis lateralibus obtusis, column alis oblongis clinandrioque margine 
membranaceo plicato ciliatis. 
A native of Brazil, whence it was received by Messrs. 
Loddiges, with whom it flowered in April, 1847. Its large 
yellow flowers more or less spotted in many parts with rich 
brown, give it a very handsome appearance. 
It is nearly allied to O. Gardneri, the character of which 
is repeated below. It differs from that species in having 
an inversely wedge-shaped lip, much larger basal lobes, only 
two pair of tubercles on the crest, large column wings, and 
an anther-bed, surrounded as it were by a membranous frill. 
Fig. 1. shews the appearance of this crest. 
O. Gardneri (Lindl. in Lond. Journ. Bot. 9. 662.); floribus 
paniculatis, sepalis oblongis obtusis lateralibus semicon- 
natis petalis duplo majoribus unguiculatis subrotundis 
undulatis, labello transverso emarginato basi auriculato, 
criste tuberculis duobus a fronte maximis intermedio 
minore duobus a latere minoribus linearibus binis 
alteris basilaribus circularibus verrucisque quibusdam in 
medio, column alis nanis rotundatis. —— Brazil; on trees 
in the forests of the Organ Mountains, Gardner.—— 
Allied to O.crispum and Forbesii, but distinctly separated 
by the peculiar form and tuberculation of the lip, and 
by the very small wings of the column.
