THE CYPRIPEDIUM GROUP. 
(Concluded from page 334.) 
7- PAPHIOPEDIUM. 
THIS genus comprises all the tropical Cypripediums of the Old World, 
and differs from the three others in having the dorsal sepal folded within 
the lateral ones in the bud, however much larger than them it may become 
when fully developed. It combines the ovary of Cypripedium, as here 
limited, with the general habit of Phragmipedium, and agrees with both in 
the fusiform, not crustaceous seeds. It contains about 42 known species, 
and ranges from the Himalayas and South India through the Malay 
Archipelago to New Guinea, and to Hong Kong by way of the 
Philippines.
