136 WILSON EXPEDITION TO CHINA 
Salix cyclophylla Seemen in Bot. Jahrb. XXX. Beibl. LXVII. (non Rydberg 
1899) (1902); Salix. Jap. 69, t. 16, fig. -F (1903). — Léveillé in Bull. 
Acad. Int. Géogr. Bot. TV. 210 (1904). 
JAPAN. Hokkaido: summit of Mt. Riishiri, July 25, 1899, U. Faurie (No. 
3713; 9 type of S. cyclophylla ex von Seemen); same locality, “repens in cavels 
ubi nix fusa fuerit," June 27, 1891, U. Faurie (No. 3713; 9, ex Léveillé). Hondo: 
prov. Shinano, on Yatsugatake, very rare, alt. 2800 m., August 1, 1910 (ex Herb. 
Sakurai; 9); same locality, August 1907 (ex Herb. Yokohama Nursery Company; 
9); same prov., on Siroumatake, August 8, 1908 (ex Herb. Tokyo sub nom. 
S. arctica); Dailenyezan, August 1912, Nakamura (types of S. Nakamurana ex 
Koidzumi). ; 
The leaves of this species are rather variable in shape, but there is otherwise no 
real difference between Koidzumi’s species and von Seemen’s plant according to 
Matsumura’s plate, and I cannot separate these twoforms. Von Seemen’s name 
having been used earlier by Rydberg for another species must be changed. The 
specimens before me have almost entire or not deeply cleft stigmas, and the pedi- 
cel of the ovaries is more or less distinct, while in von Seemen’s plate the stigmas are 
represented as deeply cleft and the ovaries almost sessile. 
Sect. DIPLODICTYAE Schneider, n. nom. 
Salix, sect. Arcticae 1 Rydberg, in Bull. N. York Bot. Gard. I. 263 (pro parte) 
(1899). 
Frutices prostrati ramulis ramisque radicantibus v. nani ramulis plus minusve 
erectis. Folia integra, superne ut videtur stomatibus paucis instructa, subtus pal- 
lida, satis firma, saepissime distincte petiolata (petiolis saepe 14-14 laminae longis). 
Amenta apice ramulorum foliiferorum multiflora, densiflora; flores c' glandulis 
duobus (an semper?) instructi, glandula dorsali saepe minima, antheris (an semper?) 
rubescentibus; flores 9 glandula una ventrali; ovaria subsessilia v. brevipedice 
lata, plus minusve pilosa v. tomentosa, stylis distinctis apice saepe bifidis, stig- 
matibus bifidis elongatis (? v. brevibus). 
Rydberg includes in this section (with some doubt, I believe) S. polaris Wahlen- 
burg, see p. 139, and also S. glauca Linnaeus. Von Seemen (in Ascherson & Graebner, 
Syn. Mitteleur. Fl. YV. 162 [1909]) says that S. arctica Pallas, S. Brownei Lundstrom 
and S. ovalifolia Trautvetter belong to sect. Myrtosalix. It is difficult to ge 
the species No. 103-106 and their relatives. It is unfortunate that Rydberg di 
not apparently pay any attention to the glands of the c" and 9 flowers.

! The name Arcticae (Arctica) was first used by Andersson (in Ofvers. K. ie 
Akad. Fürh. 1858, 119 and in Proc. Am. Acad. IV. 59 [Salic. Bor.-Am. 13] [1858 
for a section containing S. Hookeriana Barrat, S. speciosa Hooker & Arnott, ete- 
which Andersson (in De Candolle, Prodr. XVI. pt. 2, 274, 275 [1868]) referred to 
sect. Niveae.
