I regard the subspec. amplexicaulis, var. multinervis distinct from var. genuina 

 Schneider, n. comb. (»S. amplexicaulis Chaubard, 1. c. ; *S. purpurea, b amplexicaulis 

 Boissier, Fl. Orient. IV. 1187 [1879]): Folia in comparatione angustiora, acutiora, 

 distinctius v. angustius serrata, usque ad 6 cm. longa et ad 1.5 cm. lata. 



S. purpurea, subspec. amplexicaulis, var. petiolata, subvar. angustifolia Koidzumi, 

 1. c. 92, from Hokkaido seems to be only a form of subspec. eupurpurea, var. typica 

 with opposite leaves. 



Shirasawa, on his plate (8, 1. c), figures 9 flowers, which may belong to S. Gilgiana 

 Seemen, but the color of the bracts of both his 9 and cf flowers is yellowish brown. 



The typical S. purpurea Linnaeus has sessile ovaries and sessile or subsessile short 

 stigmas; the color of the young anthers is purple. 



There is also the following doubtful variety: 



Salix purpurea, var. stipularis Franchet in Nouv. Arch. Mus. Paris, s^r. 2, 

 VII. 91 {PL David. I. 284) (1884). — Burkill in Jour. Linn. Sac. XXVI. 532 (1899).
