flowers of some forms of D. kashmirionum, it is quite possible that kashmirianum and Jacquemontianum 
are descendants of D. speciosum, whilst D. Brunonianum may come from a common stock with D. elaium. 
If we deny specific value to glandular hairs and the ebsence or presence of a musky odour, we will have 
to regard D. Jacquemontianum as a subspecies of JD. kashmir/anum, but it cannot be united with D. 
Diunonianum.

DELPHINIUM viscosum, И, f. её T. 
An examination of the rich material collected under the direction of Dr. King proves this species 
іо be rather polymorphous; and if it were not for the existence of intermediste forms it would be 
possible to split it up into two or thres tolerably well-defined species. Particularly variable is the 
indumentum of the ovaries; but a critical study of this character leads to the conclusion that, here as 
everywhere, the indumentum even of tne carpels is only a feeble peg to suspend a species from. 
The following are the varieties of D. viscosum which may at present be distinguished :— 
Var. а. CHRYSOTRICHA, P. В.; middle-sized; leaves deeply trilobate, the lateral lobes lobulate ; 
inflorescence usually few-flowered; bracts, bracteoles, and upper surface of leaves densely 
clothed with soft adpressed greenish-go'den hairs; bracts conspicuous, more or less like the 
leaves; bracteoles elliptic oblong or oblong-lanceolate, sometimes three-notched or trifid at 
the apex; spur subconical, scarcely or distinctly shorter than the silky sepals; ovaries 
silky.—Eastern Nipal: near Kanglanamo and Nirpokri 13,000’ (King’s collectors 1) ; 
Sikkim: in the Jongri district (King’s collectors /). 
Var. В. силата, P. B.; а middle-sized or rather tall herb; leaves deeply sub-5-lobed, scarcely 
hairy above ; inflorescence of one or a few flowers; bracts conspicuous, sepals subvilloso 
with yellow or white hairs; spur conical or subcylindric, often quite as long as the sepals; 
ovaries ciliate along the ventral suture, otherwise glabrous, rarely entirely without 
hairs,—Sikkim, 15--10,000” (H. f. et Т. /), Western Sikkim (King’s collectors ^. 
Var. у. connecrens, P. B.; а tall or middle-sized herb; leaves plurilobate, shortly hairy or 
glabrescent above; sepals hirsute with yellowish hairs, but not silky; spur thick-conical, 
straight or incurved or uberiform, about as long as the sepals; ovaries ciliate at the 
ventral suture, otherwise subglabrous, but follicles ciliate and subhirsute.—Sikkim: 
Lebu valley (Gammie !). 
Var. 6. GIGANTOBRACTZA, Р. B.; a tall herb; leaves multilobate, upper surface rather 
densely and adpressedly раа: ; inflorescence many-flowered ; bracts and _ bracteoles 
often very large, lobed or entire and oblong-linear; sepals sericeo-villose with yellow 
hairs ; spur conical, shorter than the sepals, more rarely nearly equal to them in length; 
ovaries wholly hirsute.--Sikkim ; on the a and Natu-la; Chumbi: near Kung-bur 
(King’s coll. 1). 
Evidently a variety of D. viscosum and having its place between var. chrysotrichum and var. ciliatum 
is Huth’s Delphinium trilobatum (Neue Arten der Gattung Delphinium tiré а part du Bulletin de ? Herbier 
Boissier, tome I, No. 6, 1893). There is no specimen of Anderson’s, exactly tallying with Dr. Huth’s 
description, in the Calcutta Herbarium. The following is a translation of the description of the form 
referred to:—Stem shortly pubescent, simple, one-or few-flowered ; petioles long, sheathing ; leaves rounded, 
3—5- partite, segments sub-cuneate crenate, incised, glabrous above, subpubescert below, bract on the pedicel 
inultifid pubescent ; bracteoles very large, close to the flower, trilobate, densely pubescent, 20 mm. long ; 
spur straight, conical, 15 mm. long; sepals densely golden-pubescent, 30 cm: long; staminodes atro- 
violaceous, upper ones hairy at the apex, with a straight spur, the lower ones yellow-bearded, bifid, 
divisions lanceolate produced at the tip; immature follicles glabrous.—This description would apply to a
