SALICACEAE. — SALIX 171 



170. Salix kouytchensis Schneider, n. sp. 



Salix Duclouxii, var. kouytchensis L6veill6 in Bull. Soc. Bot. France, XVI. 298 



(1909). 

 Salix Duclouxii L6vei\\6, Fl. Kouy-TcMou, 381 fnon L6veiU(5, 1909) (1915). 



CHINA. Kweichau : " bord de la riviere de Ouen-Tsen-Kiao (Kouy-Tin)," 

 Nov. 23, 1902, J. Cavalerie (No. 728; fruiting type). 



I have received from the author a small piece of a branchlet with a fruiting cat- 

 kin which I describe as follows: 



Ramuli satis dense breviter adpresse albo-sericei, substriati. FoUa lanceolata, 

 utrinque acuta v. apice obtusiora, supra sparse sericea, in sicco brunnescentia, costa 

 nervisque subprominulis, subtus distincte pallidiora, distinctius, initio ut videtur 

 dense, sericea, glabrescentia, nervis costaque subprominulis, minutissime reticulata, 

 margine satis dense glanduloso-serrato-dentata (dentibus 5-7 pro 1 cm.), circiter 

 1.8 cm. longa, 0.5 cm. lata; petioU 2-3 mm. longi, plus minusve sericeo-villosuli. 

 Amenta breviter pedunculata, basi foUis 1-2 suffulta, sericeo-villosa, circiter 2.5 cm. 

 longa et 1 cm. crassa. Fructus sessiles, ovato-oblongi, subacuti, sericei, stigmatibus 

 oblongis bifidis sessihbus coronati. Glandula 2-3-fida, partibus linearibus, bracteia 

 triplo brevior. Bracteae oblongae v. obovato-oblongae, obtusae, margine sericeo- 

 villosae, faciebus subglabrescentes. 



The deeply cleft gland and the rather obtuse bracts seem to distinguish this species 

 from S. Duclouxii L6veill4. In the shape of the bracts it resembles S. Bockii See- 

 men, but the bracts of that species are often rather acutish and the leaves are much 

 more silky and mostly obtuse at the ends. S. kouytchensis seems to flower in the 

 autumn, and it needs further study to decide whether it is a good species or only 

 a variety of S. Bockii Seemen or of S. varicgata Franchet. 



171. Salix pycnostachya Andersson in Jour. Linn. Soc. IV. 44 (1860); in De 

 Candolle, Prodr. XVI. pt. 2, 309 (1868). 



INDIA. Kashmir : Zanskar (Gauskar, misprint in Andersson), "reg. alp., alt. 

 13000 ped.," T. Thomson (d' and9 types). 



This species is described with glabrous ovaries, while Hooker f. {Fl. Brit. Ind. 

 V. 636 [1888]), and Brandis (Forest Fl. Brit. Ind. 470 [1874]) say: " capsules . . . 

 silky." They also say that the catkins stand " on leaf-bearing peduncles," although 

 they are nearly sessile in the type. I suppose there may be some other forms mixed 

 up with our species, or it may be connected with the doubtful S. oxycarpa An- 

 dersson by intermediate or hylirid forms. S. pycnostachya, so far as I know, has 

 sessile glabrous ovaries with short styles, nearly entire obtusish leaves, obovate 

 bracts, and entirely united filaments, the var. alpina being a little more hairy 

 on the young shoots and leaves. See also S. oxycarpa Andersson and the keys on 

 p. 80 and p. 88.

INDIA. Kashmir: Zanskar " reg. alp. alt. 13-14000 ped.," T. Thomson 

 (c? type); " Tibet, Ladak, Timti La pass," July 2 and 3, 1856, Schlagintwdt (No. 

 6531; sterile). 



This variety seems to be only a dwarf alpine form with smaller leaves and 

 catkins. It may belong to S. oxycarpa Andersson because the leaves are somewhat 

 denticulate.
