96 ANNALS OF ROYAL BOTANIC GARDEN, CALCUTTA. 
spur subulate or slender, cylindrical, more or less curved, 15—20 mm. long ; nectarial 
spurs thin, awl-shaped, slightly ineurved or recurved; ovaries hairy all over; lamina 
oi anterior staminodes suborbicular, shortly bilobed, dise and base sparsely beset with 
short hairs, glabrous below; seed-scales rather short, adpressed ; leaves of D. sanicule- 
filium. (Griffith, Aighanistan, 156 suppl. list; No. 45, Herb. East Ind. Comp.). 
D. denudatum, Wall, is very closely allied to D. saniculifolium ; not only are its sepaline spurs 
very often gibbous, but even the glandular hairs which are often present on the floral axis of forms 
of D. sanieulifol,um, sometimes make their appearance in a similar position in specimens of D. denudatum. 
The latter can, however, be always distinguished from the former by the seed-scales being laxly, 
not closely, imbricate. Some specimens of D. denudatum agree nearly exactly with Don's D. paucificrum, 
which has, according to Don’s deseription, neciarial staminodes like those of D. denudatum, and not 
like those of D. Ajacis. The fact that Hamilton suggested D. consolida on his sheet has little weight, 
as various other guesses of his were equally wide of their mark. There would, however, be little 
use in changing the name of D. denudatum after it has obtained the sanction of long usage, the 
more so as the name of D. pvuciflorum has been applied by cther authors to other species, and is 
therefore somewhat diseredited.

DELPHINIUM INCANUM, Royie, 
Rhizome woody, cylindric or subtuBerous, descending. Stem erect, branched, terete 
or more or less angular, in flower 50—120 cm. high, 4—8 mm. thick near base, either 
wholly eanescent with crisp usually downwards directed hairs or glabrescent downwards 
or rarely upwards densely pubescent with yellow glandular hairs. Branches elongate, 
spreading or erect-patulous, 10—30 сш. long. Leaves on the lower surface canescent, 
more rarely puberulous, on the upper surface puberulous or pubescent; lower leaves 
shortly or long-petioled, upper ones subsessile; ihe longer petioles moderately dilated at 
the base, sometimes 5 сш. long; shorter petioles scarcely dilated, strongly striated with 
parallel nerves; lamina of lower leaves trisect to the base, lateral segments asymme- 
trically bisect. segments repeatedly pinnatisect, ultimate divisions lanceolate-linear, 
acute, apiculate, 2—4 mm. broad, nerves prominent beneath; upper cauline leaves smaller 
than the lower ones, somewhat less divided, lacinulae more acute. Flowers conspicuous, 
arranged in rather dense racemes, Pedicels at the base with a linear-lanceolate acute 
bracts of a length of 3—7 mm., 5—15 mm. long in flower, in fruit sometimes 25 mm., 
shorter than the spur, at or near the base, rarely above the middle, with 2 usually 
opposite linear bracteoles of the same length as the bract or shorter. Sepals bright blue 
or purplish, spreading, elliptic or the anterior ones subobovate, 10—18 mm. long, 7—11 
mm. broad; anterior and posterior ones very shortly acuminate, outside densely and 
minutely grey-pubescent, lateral ones rather obtuse and broader, pubescent along the 
middle; spur about as long as the lamina or 3 as long, horizontal ог ascending, 
subcylindrie, more rarely subulate, straight or somewhat curved, at the tip obtuse ог 
subacute or abruptly narrowed, often narrower in the middle. Nectariferous stami- 
nodes shorter than the sepals, glabrous, anterior margin upwards bent back at nearly
