Bupleurum."] LXI. UMBELLIFER^E. (C. B. Clarke.) 675 



Seed nearly terete. The Kashmir and Chumba examples are much more slender 

 than the Sikkim. 



4. B. jucundum, Kurz in Seem.' Journ. Bot. 1867, 240; lower cauline 

 leaves short-petioled obovate upper ovate amplexicaul deeply cordate, bracteoles 

 4-5 oblong acute usually shorter than the umbellule, fruit elliptic-oblong 1 , 

 ridges prominent, furrows 3-vittate. B. sachinalense, F. Schmidt Reis. Amur- 

 lande, 135. B. heterophyllum, Jacquem. mss. (not of Link).

Stems 1-2 ft., erect from a decumbent base, corymbose with long branches. Lower 

 cauline leaves 1-1^ in., orbicular, petiole scarcely 1 in. ; upper 1-2 in., orbicular or 

 ovate-oblong, mucronate, not peltate; primary nerves 10-20, palmate; transverse 

 nerves numerous, distinct, oblique, reticulating. Bract 1, |-^ in., ovate, foliaceous, 

 often amplexicaul or cordate, occasionally ; bracteoles 4-5, usually in., often ; 

 rays 5-8, somewhat stout, angular ; pedicels about half as long as the carpels. 

 Carpels nearly as in B. Candollii, but rather longer, in. B. aureum, Fisch., differs 

 in the much larger bracteoles, and the often perforate upper leaves. 



VAR. cachemirica; lower cauline leaves linear-oblong or linear, upper ovate- 

 lanceolate, ridges subalate. Kashmir, alt. 7500-10,000 ft., C. B. Clarke-, common. 

 Lower cauline leaves 5 by | in. Bracts often ; bracteoles of 1-4 oblong or linear 

 frequently 0. The extreme forms of this with tall simple stem corymbose near the 

 summit, narrow leaves, and umbels nearly without bracts or bracteoles appear very 

 distinct from B. jucundum, but there are numerous intermediate forms. 



5. B. Thomson!, C. B. Clarke ; cauline leaves linear upper lanceolate 

 or ovate cordate-amplexicaul, bracteoles 5-9 lanceolate acuminate or linear, 

 carpels glaucous 5-winged, furrows 4-3-vittate.

 7000-9000 ft., T. Thomson. 



Erect, 2-3 ft., corymbose. Upper cauline leaves 2-4 in., lanceolate, acuminate, 

 uppermost sometimes ovate, transverse reticulating nerves obscure. Bracts usually 

 0, sometimes 1-2 lanceolate: rays of the umbel 6-10, 1-2| in.; bracteoles usually 

 as long as the flowering umbellules, caudate ; rays of the umbellule often 20, about 

 half as long as the mericarp. Fruit in., oblong, subquadrate ; carpels terete, wings 

 more than half as broad as the nucleus ; carpophore very thin, 2-partite. This has 

 been supposed to be allied to B. diversifolium ; but the foliage seems nearer that of 

 B. jucundum, var. cachemirica ; it should be compared with B. polyphyllum, Ledeb. ; 

 Boiss. Fl. Orient, ii. 851, of which no authentic example is at Kew. 



6. B. diversifolium, Rachel PI. Ban. 68, t. 28, fig. 57; upper cauline 

 leaves lanceolate caudate base ovate amplexicaul scarcely cordate, bracteoles 

 5-8 narrow-lanceolate acuminate shorter than the fruiting umbellules, ridges 

 distinct, furrows 3-vittate. Reich. Ic. PI. Germ. t. 1885.

 alt. 9000-12,000 ft., C. B. Clarke. DISTRIB. West Asia, South-East Europe. 



Lower cauline leaves linear, hardly broader upwards ; middle cauline completely 



elexicaul. Bracts 0, or 1, small, lanceolate: rays of the umbel 8-14; pedicels 

 in. Fruit in. glaucous, in outline oblong ; disc brown, subprominent. 

 ted with B. falcatum, Linn, both by Keichenbach 1. c. and in Boiss. Fl. Orient. 

 ii. 850 : it differs in the completely amplexicaul, usually inflated, base of the cauline 

 leaves, the lower leaves linear not at all obovate, the fruits glaucous much more 

 strongly ribbed. Whether regarded as a species or variety, India produces the plant 

 of Rochel in its most characteristic form.
