in April, 1910, when our figure was prepared. In the 
genus our species is most nearly allied to L. Millsoni, 
Rolfe, one which has not yet been introduced to cultivation, 
and to L. purpuratus, Lindl., figured at t. 7921 of this 
work. Though the natural conditions cannot be reproduced, 
it is found that a Lissochilus thrives best when grown under 
stove conditions, fully exposed to strong sun, in a compost 
consisting of good turfy loam, leaf mould and sand in equal 
proportions. Abundant water and liberal treatment with 
cow manure is needed during the growing period; after 
flowering is over the plant should be gradually dried off, 
and the tubers stored at a temperature of 50°—-60° F. until 
the following spring.
