Ihave 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. Folia 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 em.), circiter 
1.8 cm. longa, 0.5 em. lata; petioli 2-3 mm. longi, plus minusve sericeo-villosuli. 
Amenta breviter pedunculata, basi foliis 1-2 suffulta, sericeo-villosa, circiter 2.5 cm. 
longa et 1 cm. crassa. Fructus sessiles, ovato-oblongi, subacuti, sericei, stigmatibus 
oblongis bifidis sessilibus coronati. Glandula 2-3-fida, partibus linearibus, bracteis 
triplo brevior. Bracteae oblongae v. obovato-oblongae, obtusae, margine sericeo- 
villosae, faciebus subglabrescentes. 5 f : 
The deeply cleft gland and the rather obtuse bracts seem to distinguish this species 
from S. Duclourii Léveillé. 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 
& variety of S. Bockii Seemen or of S. variegata Franchet.

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. orycarpa An- 
dersson by intermediate or hybrid forms. S. pycnostachya, so far as 1 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. ozycarpa Andersson and the keys on 
P. 80 and p. 88.

catkins variety seems to be only a dwarf alpine form with smaller leaves and 
It the leaves are somewhat 
denticulate, may belong to S. ozycarpa Andersson because the
