SALICACEAE. — SALIX 159 
Von Seemen supposes that this species may be of hybrid origin, S. viminalis 
Linnaeus being one of the parents. I am inclined to believe that S. sachalinensis 
represents a good species, but there may be some hybrids between this species and 
S. viminalis or other species. See also under S. Miyabeana Seemen, p. 166.

ype; 9). 
The leaves are not yet fully developed and I cannot find any other difference 
between this form and S. sachalinensis. I suppose Faurie's Nos. 265 and 270 from 
Hokkaido are best placed under this variety.

This species is said by von Seemen to be found in Mandshuria, but the interpre- 
tations of it by different authors differ widely. Smith's type was well figured and 
described in 1803: “ Nectary long cylindrical, obtuse. Germen on ashort stalk, ovate, 
downy. Style a little elongated. Stigmas remarkably long, awl-shaped, recurved, un- 
divided.” Seemen, 1. c., says that in S. stipularis the style is longer than in the type, 
which is S. dasyclados Wimmer (in Flora, XXXII. 35 [1849]) ; of this von Seemen, l. c. 
178 (1909), says that the style is as long as the ovary. According to von Seemen, 
S. dasyclados was collected by Maximowiez in Amurland. The specimen before 
me (ex Herb. Gray) shows ovaries with short pedicels of about the length of the 
style and of the long stigmas, and agrees with S. opaca sensu von Seemen. After 
all, I am not convinced that either S. stipularis Smith or S. dasyclados Wimmer 
Occurs in eastern Asia. There may be hybrids between S. viminalis Linnaeus and 
any species of sect. Capreae, but it is always a most difficult matter to refer such 
hybrids to any form already described. This species has been omitted in the keys.

So far as I can see, this species was never described by Andersson. Schmidt, 1. c., 
mentions * S. opaca Andersson in sched. hort. bot. Petr." as a synonym, and he 
never described S. stipularis f. amurensis, cited by von en. This last name 
e only mentions under S. sachalinensis, saying: “. . . foliis concoloribus ab affi- 
nibus S. stipulari amurensi (opaca And.) et udensi Trautv. differt." Herder, in 
ct. Hort. Petrop. XI. 428 (1891) only cites specimens under the name S. opaca
