There is a Chinese 9 specimen collected by Wilson in Chili, near Tientsin, April 

 18, 1909, which has very yellow glabrous branchlets with precocious aments the 

 flowers of which much resemble those of S. Miyabeana, but it may be S. purpurea 

 Linnaeus with yellowish bark. For further information, see under S. Pierotii 

 Miquel and in the keys (p. 79 and p. 90). 



There seems to be a variety of this species with tomentose branchlets, judging 

 by a cf specimen collected by Mochizxiki, 1904, at Nikko (in collect. Jack) and 

 a sterile specimen collected by C. S. Sargent, Oct. 1, 1892, at Aomori, banks of river, 

 tree, 10 m. tall. The catkins resemble those of S. lepidostachys Seemen, being 

 about 5 cm. long and 12 mm. thick.

L6veill(§ also mentions Faurie's No. 262 from the same locality, but the speci- 

 men of this number which I have seen belongs to another species. There is No. 

 267, named S. Miyabeana Seem.? which is not different from 266 or 268; it con- 

 sists of a fruiting branchlet and a sterile one, the long lanceolate leaves of which 

 are up to 10 cm. long and 1.8 cm. broad and hairy beneath while young. They 

 have hnear-lanceolate dentate stipules % as long as the petioles, which are about 

 1 cm. in length. The leaves closely resemble those of S. Miyabeana Seemen, but are 

 apparently greenish beneath and not unlike those of S. sachalinensis, var. Filgeriana 

 Schneider, which, however, are more entire. The types of <S. sapporoensis have ses- 

 sile or subsessile ovaries with very short styles, resembling those of S. purpurea 

 Linnaeus. Faurie's No. 257 from the same place and date is a httle different; it 

 is named S. daphnoides. In this specimen even the young very serrate leaves are 

 glabrous, the stipules are short, ovate and dentate, the fruits are nearly glabrous 

 with a distinct pedicel. Without fully grown leaves and young flowers it seems 

 impossible to decide whether S. sapporoensis represents a new species or may be of 

 hybrid origin. In the neighborhood of Sapporo there are many different species 

 of Salix, wild and cultivated, and hybrids of different origin may occur there.
