SALICACEAE. — SALIX 137 



NORTHEASTERN ASIA. Maritime Prov. : Plover Bay, 1865-6, TF. //. 

 Ball (ex Rydberg); Berings Island, 1891, J. M. Macoun (No. 18884^ ex Rydbcrg). 

 Also Arctic zone of Russia, Asia, North America and Japan: Kurile Islands (fide 

 Koidzumi). 



The type of Pallas's species was collected by Sujef on the Gulf of Obi near the 

 Arctic Ocean. Andersson and other botanists mixed S. arctica with several different 

 species which Lundstrom first distinguished. According to Rydberg the type has 

 thick, broad, obovate or obcordate, strongly reticulate, obtuse leaves which are from 

 2.5-5 cm. long; the catkins are thick and from 2.5-8 cm. long. It is a shrub. See 

 also the following species.

NORTHEASTERN ASIA. Yakutsk to Kamtchatka. 



Brown's type came from the Baflan Bay region. I have not seen a Siberian 

 specimen. 



This species differs according to Lundstrom and Rydberg from the true S. 

 arctica Pallas in being a prostrate shrub, with thin obovate or elliptic-lanceolate, 

 not strongly reticulate, more glabrous and often acutish leaves. The catkins are 

 exceedingly large, and the large conical capsules are a little less hairy. The 9 speci- 

 mens from Alaska which I have seen, have a very long style, and the cf a large 

 ventral and a small dorsal gland. 



105. Salix diplodictya Trautvetter in Nouv. Mem. Soc. Nat. Mosc. II. 307, t. 14

Salix Pallasii, var. diplodictya Andersson ^ in De Candolle, Prodr. XVI. pt. 2 

 285 (1868). 



NORTHEASTERN ASIA. Maritime Prov. (ex Rydberg). 



This plant differs from S. arctica Pallas and S. anglorum Chamisso (according to 

 Rydberg) in the smaller and more rounded leaves, from 1 to 3 cm. long, which are 

 rather crowded and short-stalked, and in the shorter catkins from 1 to 3 cm. in 

 length. The stem is less creeping than in S. arctica and the branches are shorter. As 



^ Chamisso also cites some specimens which according to Hooker {Fl. Bor.-Am. 

 II. 153 [1839]) belong to S. retusa Hooker, 1. c, which is the same as S. phlebophylla 

 Andersson, hence Hooker and Andersson add the name S. anglorum Chamisso as a 

 synonym to S. phlebophylla Andersson, and Trautvetter (in Act. Hort. Petrop. VI. 

 37 [1879]) accepted Chamisso's name for Andersson's species. 



' According to Andersson his variety includes the tj-pe of Pallas's S. arctica. I 

 have not seen Trautvetter's plate.
