collected in Yunnan by Pére Ducloux: his specimens are 
not definitely dated, but it is known that they were obtained 
some time prior to 1901. If B. parvifolia can be regarded 
as no more than a variety of the species to which B. Wil- 
sonae belongs, then this species has been in cultivation at 
Kew since 1896, when seeds were received from St. Peters- 
burg. As a garden plant B. Wilsonae has attractions in 
its flowers, which appear during July and August; in its 
fruit, which ripens in October ; and, according to Wilson, 
in the brilliant autumnal tints of its foliage. It is, how- 
ever, necessary to remark that, at Kew, the last-mentioned 
characteristic has not been strikingly manifested ; indeed, 
the young plants grown here have shown a marked 
tendency to retain much of their foliage thronghout the 
winter. The dwarf, spreading habit of the plant renders 
it suitable for the rock-garden in a sunny position where 
its branches can overhang some miniature cliff. It prefers 
a loamy soil and is very easily increased by means of seeds.
