The interesting Catasetum now figured was presented to 
the Kew Collection by Mr. W. Fox, by whom it had been 
found in November, 1911, growing on a dead stump near an 
Indian house on the River Igaraparana, a tributary of the 
River Putumayo in Peru. It has been grown in a tropical 
house under the treatment suitable for other members of 
the genus and has thriven well. It flowered for the first 
time in March, 1913. Owing to the numerous filiform 
appendages on the labellum, C. microglossum may be 
regarded as an ally of C. barbatum, Lindl., a species figured 
at t. 3514 of this work under the name Myanthus barbatus. 
It differs, however, from C. barbatum and from all the other 
members of the same group in having a greatly abbreviated 
and saccate lip with, as a consequence, the aggregation of 
the appendages in a dense mass. The tips of the sensitive 
antennae are partially embedded among the filaments of 
the lip.
