the genus 7'ripterygium requires alteration. ‘T'wo kinds of flower 
occur in this genus, as in some other members of this family: one 
is hermaphrodite and the other male with unfertilized ovules. The 
male flower assumes the same appearance as the hermaphrodite, - 
with the difference that the stigma is imperfectly lobed, and. 
incapable of receiving pollen grains. Hooker's description of the 
stigma was probably based on the male flower, in which the style is 
slightly shorter than in the other, clavate in shape, and the stigma 
is more or less slightly 3-lobed. The diagnosis of the stigma in 
this genus must therefore be emended to read “6-lobed in the 
normal flower 
As to whether 7. Bullockii should be regarded as a distinct. 
species, or is merely a variety, or identical with 7. Wilfordi, I 
entirely agree with Hemsley that these two plants are the same, and 
that 7. Bullockii is not even a variety. 
One important thing to be mentioned here is the difference 
between the specimens of 7. Wilfordi from Formosa and those from 
Japan. The former is the plant described by Hooker and also by 
Hance, and the latter by Regel; it is distributed in Corea as well. 
he difference was also noticed by Matsuda, but unfortunately 
he used entirely wrong names. The Japanese ‘form appears very. 
similar to the Formosan at first glance, but differs in characters of 
indumentum, texture and crenation of the leaf, more floriferous 
inflorescence, and in the shape of the fruit 
new arrangement of the species agli forms of this genus is 
given below.

This variety is very peculiar in the shape of the fruit, which is 
deeply cut at the apex. The colour of the fruit corresponds to the 
Chinese description given in Chi wu ming shi t‘u kao, vol. gr 
fol. 15. This variety may perhaps be a distinct species, but owi 
to the lack of Spe material, we hesitate to raise it to the rank ‘of 
species,
