114 WILSON EXPEDITION TO CHINA 



The living plants of S. magnifica Hemsley look extremely distinct, scarcely re- 

 sembling any other known Willow.

S. eriostachya Andersson, of which the c? plant is yet unknown, agrees so well with 

 the other species of this section that I do not hesitate to make this, which is the 

 oldest species of the group, the type of my new section.

As far as I can judge from the description this species belongs to this (or the fol- 

 lowing) section and resembles S. plocotricha Schneider in many respects. T?he bracts 

 are " eroso-denticulata " at the apex, the leaves are up to 8 cm. in length and to 

 2.5 cm. in width, and are described as " spathulata (v. inferiora oblonga)." Not 

 having seen the type specimen, I cannot decide whether S. plocotricha Schneider is 

 only a form of this species or not.

By the kindness of the Keeper of the Herbarium of the Kew Gardens, I have 

 been able to examine Wallich's type specimen. It shows the same long foUaceous 

 peduncles, the deeply cleft styles and the broad, obovate rather truncate bracts, 

 nearly enveloping the young ovaries as they do in most of the species of this section. 

 The leaves are very indistinctly glandular denticulate or nearly entire, acute at 

 the base and hairy on both sides, especially beneath ; the petioles are from 3 to 9 

 mm. long and the leaves are up to 6.5 cm. in length and 2.3 cm. in width; with 

 2 or 3 lateral nerves in each cm. of length.
