SALICACEAE. — SALIX 151 



the very narrow lanceolate acuminate dark bracts, which are densely silky on the 

 inner side and on the margins and are nearly glabrous on the outside. The two 

 free stamens are somewhat pubescent at the very base and about twice as long as 

 the bracts; the anthers are oblong and yellow. The young leaves of which I have 

 seen only a small one (2 cm. long, 1 cm. broad) are ovate-elliptic, acute at the ends, 

 silky above and more densely silky-villose beneath. I suspect S. pachydada is 

 nearly related to S. Wallichiana Andersson and that it may represent only a form 

 of this variable species. All these forms with very precocious flowers are difficult 

 to understand from the lack of good old leaves from the same plants of the two 

 sexes from which the flowers were gathered.

The typical form (represented by S. Starkeana Willdenow and by typical S. 

 livida Wahlenberg) has glabrous twigs and leaves, which are only sometimes hairy 

 when young. As far as I can see, this form does not occur in eastern Asia or at 

 least is much rarer than the following variety.

1 Salix depressa Linnaeus (Fl. Suec. ed. 2, 352 [1755]) is, according to Enander 

 (Stud. Salic. Linn&s Herb. 102 [1907]), a mixture of S. Caprca and some hybrid forms. 

 The name S.foliolosa Af zel is only cited as a sj-nonym by Smith (in Linnaeus Fl. Lapp. 

 ed. 2, 295 [1792]). S. Starkeana Willdenow seems to be according to the citations 

 of Andersson, von Seemen and Toepffer the oldest name of any form belonging to 

 S. livida Wahlenberg or S. vagans Andersson.
