I have seen a branchlet of the type specimen which agrees very well with Anders- 
son's description, only the pubescence of the leaves and catkins is not really “ cu- 
preo-mieans," but more yellowish white. The species differs from the others of 
this section in the nearly sessile catkins, but I have only seen very young aments 
appearing with the leaves. The c^ plant mentioned by Hooker f. I do not know, 
but the 9 flowers are very much like those of S. Ernesti Schneider or of other 
species of the Eriostachyae. The ovaries are not sessile, but very short-stalked, the 
pedicel being only one third the length of the rather long gland. There is no small 
dorsal gland as in S. Ernesti. The bracts of the young flowers are very large, 
broadly obovate, round at the apex and somewhat crenulate, and nearly envelop 
the whole flower. The deeply cleft styles are about one-half as long as the pubescent 
ovaries, the stigmas are rather short, obovate, emarginate or bifide. The stout 
flowering branch resembles that ‘of S. Caprea Linnaeus or of S. daphnoides Villars 
and is apparently somewhat glaucous. The mature leaves are not yet known. 
Burkill (in Jour. Linn. Soc. XXVI. 532 [1899]) mentions S. sikkimensis from 
Yunnan (Delavay No. 2792), but I have not seen the specimen.

Arbores v. frutices alti, rarius parvi. Folia elliptica v. pleraque ovato-lanceolata 
v. lanceolata, satis magna y. mediocra, rarius parva, subtus pleraque sericea v. 
sericeo-tomentella, plus minusve nervosa sed rarius reticulata. Amenta brevius 
v. longius pedunculata, cylindrica, densiflora, € pleraque 3-12 cm. longa; flores # 
diandri glandulis 2 separatis; flores 9 v. fructus sessiles; ovaria sericea v. tomen- 
tella (in specie dubiae affinitatis glabra), stylo brevi v. satis longo, bipartito v. 
bifido, stigmatibus bifidis coronata ; glandula una ventralis. / 
ve some doubt whether the species, united by me in this new section, form a 
natural group. S. Daltoniana Andersson may perhaps be better placed in the 
preceding section, while S. Thomsoniana Andersson differs from the others in being 
a very low shrub with small leaves. 
52. Salix Daltoniana Andersson in Jour. Linn. Soc. 1V. 49 (1860); in De Candolle, 
Prodr. XVI. pt. 2, 269 (1868). — Hooker f., Fl. Brit. Ind. V. 632 (1888). — Brandis,

INDIA. Sikkim: “ reg. temp., alt. 9000-14500 ped.” (Andersson says 1868: 
14000), J. D. Hooker (type, of which I have seen a co-type). Bhutan: without 
locality, W. Griffith (No. 4498, ex Hooker). : 
Burkill (in Jour. Linn. Soc. XXVI. 528 [1899]), refers to S. Daltoniana some forms 
collected by Delavay in Yunnan, of which I have not seen specimens. He also 
describes a var. Franchetiana, the types of which were collected by David in 
Mupin and by Mussot (No. 348) at Tachien-lu. In this variety the gland appears, 
according to Burkill, to be single, while two are present in the type. Without 
having seen this specimen, I cannot tell anything about this variety or about Dela- 
vay’s No. 988 from Tali in which Burkill recognized “a hybrid between S. Dal- 
toniana and S. elegans” (= S. denticulata Andersson). The last species, so far 
as I know, is a native of the northwestern Himalaya and Afghanistan and does 
Dot oceur in China. 
S. Daltoniana, var. crassijulis Andersson (in De Candolle, Prodr. XVI. pt. 2, 
279 [1868]), the type of which was collected by J. D. Hooker in Sikkim between 
9000-14000 ped." I know only from Andersson's description, but I think it 
belongs to a different species.
