A native of South America and Mexico which has been introduced

unfortunately dies out after seeding. If prevented from seeding by

or three years,

S. T. Dunn. 
In 1896 Ridley described as a new genus under the above name 
(Journ. Bot. 1896, 329) an herbaceous plant of the Natural ee 
Commelinaceae which he had received in a living state from Leg 
arrangement and structure of their lowers identical with those of 
Spatholirion, and, although Ridley’s plant is an acaulescent one 
while these two are tall herbaceous climbers, there can be no doubt 
that all are congeneric 
One of the Chinese species was first collected some 30 years 
ago by Delavay, but the specimens seem to have been accidentally 
left among his sheets of bed han paper at Yunnan-fu until found 
there by Ducloux a few years ago. Meanwhile, however, the same 
plant had been gathered by the latter collector in the neighbourhood 
of Yunnan-sen and sent to Paris, where Gagnepain described it as 
a new Streptolirion, Gagnepain, working perhaps with imperfect 
material, did not appreciate the divergence from that genus shown 
by the number of ovules in each cell and the monoecious character 
of the flowers, neither of which are indeed mentioned in his 
description. 
The second Chinese species which has been received at Kew 
from Yunnan, Kweichau and Szechuen is fortunately represented 
by complete material, including fruit, so that the characters of the 
capsule and seeds of the genus can now be degecribed for the first 
time,
