The striking Mormodes here figured was introduced by 
Messrs, Sander & Sons, St. Albans, from Peru, where it had 
been obtained in the Moyobamba region by their collector, 
Mr. Forget. The species flowered for the first time in 
cultivation in July, 1909, at St. Albans, and was described 
from material supplied by Messrs. Sander, from whom a 
plaut was thereafter acquired by purchase for the Kew 
collection. This plant, which has thriven well in an inter- 
mediate temperature, under the treatment most suitable 
for the allied genus Catasetum, flowered at Kew in 
January, 1910, and developed a much longer spike with a 
more strongly three-lobed lip than the plant on which the 
original description was based. The figure here published 
has been drawn from the plant at Kew, which flowered 
again in January, 1911. MM. revolutum is allied to the 
Colombian M. speciosum, Lindl., but differs in the characters 
enumerated by Mr. Rolfe. Another species of similar habit 
Aveust, 111.
