DESCRIPTIONS OF NEW AND RARE INDIAN PLANTS. 91 
the eucullus and usually longer; whilst in Delphinium it is only indicated and in only a few species is there 
a distinct rudiment of one. With our present knowledge of Delphinium and Aconitum it is doubtful 
whether any botanist could be found who would consent to a generic separation of the two, if they 
had been originally united. It is certainly as reasonable to establish consolida as а separate genus as it 
is to allow Aconitum generic rank. Delphinium would then be distinguished from the other Hi ll-boreae by 
its monosymmetric flowers and the form of its nectaries, and it would be divided into the three 
subgenera— 
Т—Оохвотлра ; neotaries coherent into one, rarely abortive; carpel solitary. 
П.-Пкгрніхіпм VERUM; nectariferous staminodes 2, separate, claw absent or rudimentary ; 
са рејв 3—8. 
IIL— Асохітом; nectariferous staminodes 2, separate, claw at least as long as the nectary proper; 
carpels 8—8. 
The arrangement of the species belonging to Delphinium verum into sections that leave closely allied 
forms together, is a matter of great ditlieulty, and is in some cases impossible. The following classi- 
fication, to a certain extent foreshadowed by the lamented Professor Prantl in “ Die Pflanzenfamilien,” is 
here attempted. A different grouping will, according to a friendly communication of Professor E. Huth, be 
adopted by him in his monograph on Delphinium, which will shortly be published in Engler's Jahrbücher, 
and which will fora long time to come form the standard work on this highly interesting genus. 
Section I.—DELPHINELLÆ; annual; anterior staminodes glabrous; seeds either depressed-spherical, 
the wrinkles forming an open cup at the top (Delphinelle proprie), or triangular-sub- 
globose, areolate-rugose (Stuphisagree). 
Section 11.—1зоснкп„ж®ж; perennial; anterior staminodes hairy, similar in colour to the sepals, 
usually about as long as, or longer, rarely (in D. incamum) 3 mm. shorter than the anterior 
sepals, light coloured, usually bifid; seeds lamellate-rugose; cauline leaves usually con- 
spicuously sheathing. То this section belong--D. dasystachyum, Boiss.; D. lanigerum, Boiss. ; 
D. ithaburense, Boiss.; D. micranthum, Boiss; D. hybridum, Willd with its subspecies D. 
Jfissum, Waldst. et Kit., D. hybridum verum, D. cyphoplectrum, Boiss. ; D. quercetorum., Doiss. 
D. Szowitsianum, Boiss.; further D. incanum, Royle; D. denudatum, Wall; D. tuberosum 
Auch. ; D. genicillatum, Boiss.; D. kurdicum, Boiss.; D. Zalil, Aitch. et Hemsl.; D. saniculae- 
folium, Boiss.; D. uncinatum, H. f. et T. ; D. dasycaulon, Fresen. 
Section I11.—Homaocuro#; perennial; anterior staminodes hairy, similar in colour to the sepals 
(blue, more rarely purple), distinctly and usually much shorter than the anterior sepals, 
lamina usually orbicular or oval, entire or bilobed; seeds not lamellate-rugose, sometimes 
nearly smooth, usually with the epidermis more or less loose, especially along the edges; 
cauline leaves usually scarcely sheathing. Of Indian Delphinia the following belong to 
this section:—D. grandiflorum, Linn., incl. D. вағшент, Jacq.; D. cheilanthum, subspecies 
schizophyllum, P. В.; D. altissimum, Wall; D. pachycentrum, Hemsl., subsp. ¢sangense, P. В. 
Section 1Ү.--НЕтевоснвож; perennial; anterior staminodes hairy, very different in colcur from 
and shorter than, the (blue, purple, or variegated) sepals, usually purplish-black or chest- 
nut-brown, rarely white or yellow, lamina ovate, usually bifid, with lanceolate-acute 
segments, rarely roundish and emarginate or bilobed; seeds various; cauline leaves often 
scarcely sheathing. This is divisible in two subsections, which, when our knowledge of 
the structure of the seeds has been completed, will probably form two separate sections 
or series. 
Subsection 1.--РтевоврЕвмЖ; seeds with the loose epidermis forming wings along the edges, 
epidermis otherwise more or less puckered, but not thrown into scariose wrinkles.—D. 
stapeliosmum, P. B.; D. elatum, Linn. subspecies incisum ; D. vestitum, Wall.; D. viscosum, 
H. f. et T.; D. glaciale, Н: f. et T.; D. Brunonianum Royle, D. densiflorum, Duthie. 
Subsection 2.—Lxpiposperm”; seeds lamellate-rugose.—D. speciosum, M. Bieb., subspecies ranun- 
culifolium, Wall.; D. kashmirianum, Royle, aud D. Jacquemontianum, Camb.
