SALICACEAE. — SALIX 159 



Von Seemen supposes that this species may be of hybrid origin, S. mminalis 

 Linnaeus being one of the parents. 1 am inchned to beheve 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.

 type; 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 diflferent authors differ widely. Smith's type was well figured and 

 described in 1803: "Nectary long cylindrical, obtuse. Germenon 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, 1. c. 

 178 (1909), says that the style is as long as the ovary. According to von Seemen, 

 S. dasyclados was collected by Maximowicz in Amurland. The specimen before 

 me (ex Herb. Gray) shows ovaries with short pedicels of about the length of the 

 Btyle and of the long stigmas, and agrees with 5. 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 sj-nonym, and he 

 never described S. stipularis f. amurensis, cited by von Seemen. This last name 

 he only mentions under 5. sachalinensis, saying: "... foliis concoloribus ab affi- 

 nibus S. stipulari amurcnsi (opaca And.) et udensi Trautv. differt." Herder, in 

 Act. Hort. Petrop. XL 428 (1891) only cites specimens under the name S. opaca 

 Andersson in Herb.
