108 ANNALS OF ROYAL BOTANIC GARDEN, CALCUTTA. 
sepaline spur stout-cylindric or thick-conical, slightly incurved, very blunt, as long as, 
ог longer than, the lamina; staminodes shorter than the sepals; lamina of anterior 
staminodes light blue, orbicular, subentire; carpels 3—5. 
Distribution: Eastern Tibet, from the northern frontier of Sikkim to Setchwan. 
The variety from Southern Tibet was figured by the writer about three years ago for the present 
volume of the Annals under the name of D. Kingianum; on receiving Pratt’s plants he at once 
recognised the close relationship between the form in question and a new Delphinium gathered in the 
Tachienlu region. Meanwhile Mr. Hemsley described the latter under the name of D. pachycentrum, for 
which reason the writer has, by the kind permission of Dr. King, substituted a new plate for the 
original one and rechristened the Southern Tibetan form subsp. tsangense. We have thus— 
Subspecies I—Hemsteyr; stem very stout (7—9 mm. in the middle), like the pedicels densely pubescent 
with minute retrorse crisp hairs; inflorescence strictly racemose; flowers crowded; pedicels егесі; sepals 
on both sides minutely and softly pubescent ; sepaline spur about 3 the length of the lamina, stout-cylindric, 
blunt; lateral sepals obovate-oblong; carpels usually 8 or 4.—Tachienlu region (Pratt '). 
Subspecies II.— TsascENsis, Р. Brühl; stem rather slender (3—5 mm. in the middle), glabrescent 
below, upwards hairy, more or less glandular; inflorescence racemose, subpaniculate or subcorymbose, 
somewhat lax; pedicels patulous; sepals glabrous inside, the anterior ones and posterior one hairy all 
over on the outside, the lateral ones puberulous along the middle; sepaline spur about as long as, or 
very slightly shorter than, the lamina, stout cylindric; carpels usually 5, more rarely 3.—Between tLe 
northern frontier of Sikkim and Lhassa (King’s collector 1). 
Var. а. ЮАЅҮСАЕРА P. B.; ovaries villose-pubescent. 
Var. 8. іжосавғра, P. B.; ovaries quite glabrous or slightly ciliate along the ventral suture. 
Description of subspecies tsangensis.—Stem lerest, subflexaose, subangular, densely 
foliose upwards, glabrescent downwards. Upper infrafloral leaves shortly-pstioled; blade of 
firm texture, subpentagonal in outline, cordate, nearly iscdiametric, trisect, pubescent, 
especially along the margin and the nerves; middle segment oblong lanceolate, towards 
the base cuneate, 3—4 cm. long, 12—15 mm. broad, pinnately trifid, acute; middle 
lacinia 1 the length of the segment, incised with 2 or 3 serratures on either side; 
lateral lacinize twice or three times shorter, obliquely ovate, pauciserrate; lateral leaf- 
segments trapezoidal, very broad-cuneate, unequally bipartite beyond the middle, 
25—52 mm. broad; intermediate partitions similar to the middle segment; outer ones 
broader, unequally bifid, sparsely incised-serrate ; all serratures apiculate; petioles not 
dilated at the base, semiterete, canaliculate, 15—5 mm. long, hairy, sparsely glandulose. 
Inflorescence many-flowered, 4—12 cm. long; flowers on the lateral brauches rather 
crowded. Floral axis beset with glandular and eglandular hairs, Floral leaves sub- 
conform to lower ones, but gradually more shortly petiolate, the uppermost ones rather 
more simple. Pedicels patulous, terete, lower ones 2:5—5 cm. long, uppermost 1—2°5 
сш. long, indumentum like that of floral axis, towards the apex bibracteolate and villous. 
Bracteoles opposite, linear, acute, 6—11 mm. long, hairy. Sepals membranous, раје 
blue. Sepaline spur obtuse, sometimes 2 mm. shorter than the lamina. Nectaries glabrous; 
lamina oblong-subspatulate, 2—4 mm. shorter than the lamina of the posterior sepal, obtuse, 
entire; spur about as long, open laterally to about the middle, below the slit subulate, 
acute. Anterior staminodes hairy on the back, lamina 6—7 mm. long, about as long as 
the claw. Stamens 25—30, subequal, 7—9 mm. long; filaments membranous, dilated 
below, with the wings attenuated upwards and ciliate; anthers elliptic, 1 mm. long. 
Carpels 5, rarely 3, 5—7 mm. long; ovary ovoid-oblong; style about 2 mm. long, a: 
first straight but finally recurved. Ovules numerous.
