1920] SCHNEIDER. NOTES ON AMERICAN WILLOWS. X 67 



The same form is in Herb. Ottawa under No. 24749 (fruiting branchlets) 

 bearing the label "Salix Scouleriana Fl. Bor. Am. Dr. Richardson." Bebb, 

 in 1891, made the note to it: "ticket evidently misplaced." If it is, how- 

 ever, a specimen of Richardson's (ex Herb. Mus. Brit.) the name only may 

 be a lapsus calami. On the same sheet there is also a sterile branchlet 

 which is not described by Richardson. In his descrii)tion everything 

 fits the specimen in Herb. N. Here we find on the same sheet a female speci- 

 men collected by Richardson on July 20, 1827 "N.Y. House." According 

 to Franklin (Narr. second Exp. Polar Sea, 315 [1828]) Richardson on July 8, 

 1827, was at Fort Alexander, Manitoba, whence he went to ]VIontreal. 

 Where he was on the 20th of July is not stated, and I have been unable to 

 find out where "N.Y. House " is. The specimen is identical with that from 



Fort Franklin. 



There is, however, in Herb. Ottawa another specimen collected by Rich- 

 ardson and labeled "S. rostrata Richards. Franklin Expedition, between 

 Forts Simpson and Chepewyan" (Chapewyan on Franklin's map). This 

 specimen has narrow elliptic-lanceolate leaves which soon become almost 

 glabrous beneath, and glabrous branchlets. Richardson's statements 

 "folia sesquipollicaria, cxstipulata, pube sericea caduca ? vestita subtus 

 grisea sub-glauca" might refer to this glabrescent form. But if we take 

 this specimen for the type, S. rostrata sensu stricto would be the same as 

 our present var. perrostrata, and we should be obliged to take up the name 

 ar. ohovata of Andersson for the eastern form which we at present regard as 



the type. 



As I have not seen the material of the Hookerian Herbarium I use the 



name Bebhiana {rostrata) for the pubescent form which, however, is closely 

 connected with var. perrostrata by numerous intermediate forms. Rich- 

 ardson's glabrescent specimen has rather thin, acute leaves which measure 

 up to 4:1.2 cm. They are partly distinctly glaucescent beneath, the pu- 

 bescence being very thin. The fruiting aments are old, the fruits measure 

 about 8 mm., the pedicels about 4 mm. in length, and their pubescence is 



very thin. 



Hooker, Barratt, Torrey and Carey used the name S. rostrata Richardson. 

 When Andersson first dealt with the American Willows he named this 

 species S. vagans cinerascens occidentalis. He cites Richardson, Gray and 

 Hooker but he does not mention any specimens, and he also refers to it 

 some Siberian forms. The quotation "S. depressa cinerascens Trautv." 

 has been omitted in Sal. Bor. Am. Gl. All the other forms of S. vagans 

 given by Andersson in 1858 are of European origin. In 1807, he has a 

 S. vagans 1. S. rostrata with the synonym S. rostrata Richardson and S. 

 vagans occidentalis Andersson. This sub-species rostrata includes only 

 American forms, and Andersson enumerates the following five varieties of 

 it: latifoUa, Janata, ohovata (with forms suhambigua and subrepens), lance- 

 olata and glabrescens. To his second subspecies cinerascens Andersson, in 

 1867, does not refer American forms, but under his third subspecies, S. 

 t:,.u., ttto flnrl Q irar nmprimna wbich is ssid to be connected by inter-
