localities, all in Western Szechuan. The shrub, which 
attains a height of six to nine feet and is notable on 
account of its sometimes red and at other times orange 
glandular fruits, occurs in woodlands and thickets up to 
an elevation of 9400 feet above sea-level. The plant 
was first introduced to cultivation, from Mr. Wilson’s 
earlier seeds, by Messrs James Veitch and Sons, and in 
1915 a flowering branch stated to be of Chinese origin 
and to represent one of Mr. Wilson’s plants (958a) was 
submitted to Kew for identification by Colonel S. R. 
Clarke of Borde Hill, Cuckfield, Sussex. The spray sent 
was readily identified with Mr. Wilson’s plant of the 
1903 collection (3759) and Miss Jesson, who established 
this fact, regarded it as a very distinct variety of Ribes 
Maximowiczii, Bat., a species discovered by Mr. Potanin 
in Eastern Kansu, which is characterised by its short 
extremely compact fruiting racemes, with the individual 
fruits closely covered with coarse bristles. The affinity 
between the two shrubs is indeed extremely close, but the 
additional material now available shows that it is more 
_ Satisfactory to regard Miss. Jesson’s variety as a separate 
species, readily distinguished by its much elongated 
inflorescences with more numerous flowers and especially 
by the much shorter and less plentiful glandular bristles 
which cover the berries. Professor Janczewski, who has 
included the Szechuan plant now described in the species 
from Kansu which Batalin named 2. Maximowiczii, only 
knew the latter in the fruiting condition, and, although he 
Placed it in the section Berisia, was disposed to believe 
that it may really belong to his section Parilla. There 
seems now no doubt, however, that the arrangement 
actually adopted by Janczewski is correct, for the plant 
now figured as RF. Jessoniae and named in compliment to 
the lady who first indicated the differences between it 
and the plant from Kansu, is certainly a member of the 
section erisia, which. differs from Parilla in having 
erect in place of pendent racemes, in having no ovules in 
_ the female flowers and in having no pollen in the reduced 
anthers of the male flowers: in Parilla the male flowers 
have sterile pollen and the female have sterile ovules. 
The material for our plate has been derived, as regards 
the male inflorescence, from a plant in the collection at
