N. mexicana, Hort., non Zuce. 
Nymphexa flavo-virens is a near ally of the Mexican 
N. gracilis, Zuce., differing from that plant in its larger 
size, in the segments of the leaf being pointed, in the 
narrower, sub-acute (not acuminate) petals, in the fila- 
ments not being so dilated at the base, and in the more 
numerous stigmas. It has been long in cultivation in 
Europe, having been first described in 1852, from a plant 
that flowered in the Botanical Garden of Hamburg, and 
in July last a specimen was sent to be named by Mr. 
Moore, A.L.S., Keeper of the Glasnevin Botanical Garden. 
There is a specimen of it in the Kew Herbarium from 
the Hamburg Garden, named by Professor Caspary, who 
made a special study of the genus. This specimen 
has black blotches on the leaves, and the species is 
described as having the under surface of the leaves of a 
blood-red colour. In the Kew plant the leaves are very 
pale green beneath, clouded with brown; in Mr. Moore’s 
they are also pale, but pure green. 
The native country of N. flavo-virens is unknown, but is 
probably Mexico, both because of its affinity with J. 
gracilis, and because the Kew plant was received from 
W.N. Pike, of the Floral Park, New York (in 1892) as 
June lst, 1901,
