2 to 3.5 cm. long without the peduncle which is from 0.5 to 1 cm. in length. The 

 smaller leaves are ovate or ovate-lanceolate and acute, the largest broadly 

 lanceolate, very acuminate, and up to 9 cm. long and to 2.5-3 cm. wide.

The above specimens are referred not without doubt to this species, which may 

 be planted in the northwestern Himalaya and Tibet according to Brandis and 

 Hooker f . The Willow of Kiangsu and Chusan Archipelago referred by Debeaux, 

 Burkill and others to S. alba belongs to S. babylonica Linnaeus (see p. 00).

In the types the leaves are more or less denticulate; the c? flowers have two 

 glands, of which the dorsal gland is only a little smaller; the ovaries are nearly 

 sessile and bear a short style with narrow shortly cleft stigmas. The specimen 

 No. 1116 from Afghanistan has entire leaves which are more or less silky on both 

 sides or are nearly glabrous above. The 9 flower and fruit show a short pedicel 

 nearly as long as the single gland. This interesting species needs further inves- 

 tigation. 



S. lenta Fries is a very uncertain species, found in Nepal by WalUch, according to 

 the author. The cf flowers are described as " diandri."

It is with a good deal of hesitation that 1 unite in this new section the following 

 species. The value of the presence or absence of the second (dorsal) gland in the 

 9 flower in taxonomic classification needs further investigation. It seems certainly 

 not sufficient to justify the large groups made by von Seemen (as Didymadeniae, 

 Heteradeniae and Monadeniae) based on the glands of the 9 flowers.
