This ea may later have to be separated from Z. rubrolineata, 
Hook. f. There is no dried specimen of the plant at Kew, but 
only a drawing of an incomplete specimen collected at Manipur. 
This drawing does not show the most distinctive hook-like process 
on the interior sepal which is characteristic of the specimens 
described above, but the plant agrees roughly in other respects 
with the description in Kew Bull. 1910, 300. The plant, however, 
there described has nae sepals 1- ‘5 em, in length instead of 
11-12 cm. an ique in form. Also ‘“‘costa dorso 
breviter cristata ”’ harele describes the standard of the present 
eo. which is perhaps * costa dorso supra medium ample cris-
