short time ago. It is somewhat darker in the ground colour of the sepals than 
usual, but there does not appear to be any other essential difference in the 
flower. 
Masdevallia coriacea may be taken as the type of a considerable section of 
the genus, the section Coriace#, characterised by its distinctly coriaceous 
perianth, varying from shortly and broadly to narrowly tubular, the tails of the 
sepals usually short and rigid, and the peduncles usually 1-flowered. Its exact 
limits are rather difficult to define, because a few species are somewhat anomalous, 
and its relation to other sections is not yet clearly defined. It includes, however, 
a considerable number of cultivated species, of which may be mentioned the 
following : M. calura Reus. F., M. campyloglossa Reus. F., M. civilis Reus. F., 
M. coriacea Linnu., M. demissa Reus. F., M. elephanticeps Reus. r.. M. Gar- 
gantua Reus. F., M. leontoglossa Reus. r., M. Mooreana Reus. ¥., M. pachyantha 
Reup. r., M. peristeria Reus. F., M. platyglossa Reus. r., M. porcelliceps Rens. F., 
M. Rolfeana Kraznziin, M. torta Reus. r., M. velifera Reus. F., and a few 
others ; also several species which have not hitherto appeared in cultivation. 
The requirements of these high alpine Orchids are now pretty well 
understood. They succeed best in a house with an east or north-east aspect, 
and the coolest possible treatment during hot weather, by shading and keeping 
the air, as fully charged with moisture as possible, and generally keeping them 
under what is known as cool treatment.
