flowers of some forms of D. kashmirianum, it is quite possible that L«s^mirianum and Jucquemontianum 
are descondants of D. speciosum, whilst D. Brunonianum may come from a common stock with D. elatum. 
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 D. kashmirianum, but it cannot be united with D. 
Brunonianum.

DELPHINIUM viscosum, H. کر‎ et T. 
An examination of the rich material collected under the direction of Dr. King proves this specios 
ما‎ be rather polymorphous; and if it were not for the existence of intermediate forms it would be 
possible to split it up into two or three 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 tre 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. curysotricna, Р. B.; 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-golden 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 H: 
Sikkim: in the Jongri district (King’s collectors /). 
Var. В. сплата, P. В.; a middle-sized or rather tall herb; leaves deeply sub-5-lobed, scarcely 
hairy above ; inflorescence of one or a few flowers; bracts conspicuous, sepals subvillosə 
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—16,000° (И. f. e£ Т./), Western Sikkim (Кіпа? в collectors, 
Var. y. CONNECTENS, Р. B.; a tall ог 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 1). 
Var. 8. cicANTOBRACTzA, P. B.; × tal herb; leaves multilobate, upper surface rather 
densely and adpressedly pubescent ; 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 tothem in length; 
ovaries wholly hirsute.--Sikkim ; on the Zey-lap-la and Natu-la; Chumbi: near Kung-bur

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 à part du Bulletin de ? Herbier 
Boissier, tome I, No. 6, 1893). There is no specimen of Anderson’s, exactly tallying with Dr. Huth’s 
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 
multifid 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 om. long; staminodes atro-
