140 WILSON EXPEDITION TO CHINA 



It is with some doubt that I add also the following species with glabrous ovaries 

 to this section, but I have been able to find only one gland in the cf flowers. 



110. Salix microphyta Franchet. See p. 62. 



Sect. 18. OVALIFOLIAE i Rydberg in Bull. N. York Bot. Gard. I. 274 (1899). 



Frutices humiles, plerique prostrati, truncis v. ramis radicantibus. Folia In- 

 tegra, 1-2 em. longa, subtus palUda, reticulata. Amenta pluriflora, ramulos folii- 

 feros terminantia; flores cf diandri, glandula ventrali et dorsali, antheris flavis?; 

 flores 9 ovariis pubescentibus v. glabris, stylis brevibus sed distinctis, stigmatibus 

 bifidis, glandula una ventrali v. interdum ut videtur etiam dorsali. 



I doubt if the species united by Rydberg in this section really belong in the same 

 group.

NORTHEASTERN ASIA. Yakutsk: "in terra Tschuktschorum," A. von 

 Chamisso & J. F. Eschscholtz (ex Ledebour); Maritime Prov. : "ad fl. Ajan," 

 H. Tiling (ex Herder); Kamtchatka: "in alpibus," K. H. Mertens (in herb. 

 Trautvetter). 



According to Lundstrom (1. c. 16), S. ovalifolia is nearly related to S. reptans 

 Ruprecht, but it certainly is very difficult to limit the typical forms. They are 

 apparentl}^ very variable and are connected by intermediate forms with S. arctica 

 Pallas, S. glauca Linnaeus and other species. The typical S. ovalifolia Trautvetter 

 has glabrous ovaries, the pedicels and styles are sometimes short, but distinct and 

 sometimes are wanting or nearly obsolete. 



According to the description, I believe that S. erylhrocarpa Komarov (in Fedde, 

 Rep. Spec. Nov. XIII. 165 [1914]) is the same as or very closely related to S. ovalifolia. 

 The type was collected by Komarov " in alpibus peninsulae Kamtschatkae circa 

 lacus Natshika at Kronotzkoe, et ad fontes fl. Kamtshatka, annis 1908-09." Or 

 it may possibly represent a new species of sect. Lindleyanae and may be closely 

 related to S. Souliei Seemen and S. brachista Schneider.

NORTHEASTERN ASIA. Maritime Prov. : Behring Straits, Arakam 

 Island, 18.53-6, C. Wright (ex Rydberg). 



Rydberg, 1. c, says that the tjqje is " No. 96 of Herb. Hook., Barratt & Torr. 

 from the Arctic Coast." Hooker, 1. c. (1839), cites Hooker and Arnott, 1. c. (1832), 

 where the S. retu^a is said to come from Kotzebue Sound. Seemann quotes the 

 same specimen and also a specimen from Pelly Island collected by Pullen. Seemann's 



^ Toepffer (Salicol. Mitteil. No. 4, 186 [1911]) cites a sect. Ovalifoliae Pokorny 

 (Oester. Holzpfl. 58 [1864]), but there is no such section. The name Ovalifoliae is 

 only a paragraph in a key, otherwise Pokorny has adopted the systematic arrange- 

 ment of Kerner.
