This interesting addition to the Chinese flora is perhaps most closelj' related 

 to the Uttle known S. serrata Maximowicz. This Japanese species has similar 

 but smaller leaves with axillary tufts of hairs between the principal veins below, 

 a short pedicel and foliaceous but smaller bracts and sepals. The stamens are 

 free, the ovary is glabrous and the stigmas are more minute. Part of No. 1722 

 and Henry's No. 7392" differ from the type in the presence of a more copious 

 pubescence on all parts of the plant. Henry's specimens received from Kew are 

 labeled S. monadelpha, var., and this plant is referred to by Bean {Trees & Shrubs 

 Brit. Isl. II. 553 [1914]) as S. monadelpha Siebold & Zuccarini. The Chinese 

 plant is certainly closely allied to this Japanese species, as both have monadelphous 

 stamens, a united style and short pedicels, the capsule, however, of S. sinensis is 

 the largest in the genus, while that of S. jnonadelpha is the smallest. 



Last year Wilson became well acquainted with S. monadelpha, which on the 

 island of Yakushima in particular and in other parts of southern Japan is a very 

 common tree growing from 16-25 m. tall, ■ft-ith a perfectly smooth, pale brown 

 trunk from 1.5-3 m. in girth, spreading branches, pubescent leaves, small ovoid, 

 very slightly and obtusely angled capsules from 8-12 mm. high, 8-9 mm. wide, 

 and clothed with yellowish appressed villous hairs.
