transverse obtuse-angled, four-lobed, undulated, with a minute 
apiculus in the sinus between the anterior lobes, revolute. Callus

I have had this species of Oncidiwm long under cultivation, 
and I have lost all trace of the source from whence I originally 
procured it. In the temperate house it grows and flowers freely 
either in a basket or under pot cultivation, and, like most of the 
thick-leaved Oncidiwms, it requires but a moderate supply of 
water.—W. W. S.
