North-west Himalaya ; Simla, alt. 7000-8000 ft., Edgeworth. LAHUL ; Jaeschke. 



Stem 2-3 ft. Lower leaves 12 by 8 in., secondary pinnae distant; upper pinnate 

 or reduced to sheaths. Bracts 1-4, \ in., linear, or 0; rays 12-40, 1-1 in.; 

 bracteoles 6-12, \ in., linear; pedicels very many. Fruit - in., nearly as in 

 L. marffinatum, but the carpels are longer than broad ; dorsal furrows 2-3-vittate, 

 lateral 3-vittate, commissure 6- 8- vitiate. Seed 4-6 times as broad as thick, inner 

 face plane. Edgeworth's description is most accurate; the word bivittatis in the 

 specific character being a misprint for trivittatis. He suggests that it may be the 

 imperfectly described Levisticum argutum, Lindl. 



26. SEX.XNUXH, Linn. 



Perennial, branched herbs. Leaves pinnately compound. Umbels com- 

 pound ; rays numerous ; bracts many, linear or pinnatifid, or few, small, or ; 

 bracteoles numerous, linear, serrate or pinnatifid, sometimes few small. 

 Calyx-teeth obsolete, or lanceolate or linear. Petals obovate, emarginate, 

 white or yellowish-green. Fruit ovoid or subquadrate, commissure broad, 

 more or less dorsally compressed or complanate ; lateral primary ridges 

 winged, corky or papery, dorsal and intermediate ridges approximate, equal or 

 unequal, as wide as the lateral or not, sometimes excurrent, not winged ; dorsal 

 furrows 1-vittate (or rarely 1 large deep-seated 2 small lateral superficial) or 0, 

 lateral furrows 1-4 vittate ; carpophore slender, 2-partite ; style-bases not pro- 

 minent in fruit. Seed subterete, or more or less dorsally compressed, inner 

 face plane or slightly concave, not grooved. DISTRIB. Species 35, chiefly north 

 temperate, with a South African and Andean. 



The Indian species are uniform in habit, having very compound leaves, large 

 umbels with prominent involucres, three approximated ridges excurrent on the back 

 of each carpel, and the seed not grooved on the inner face. Ligusticum differs by 

 having the dorsal furrows 3-vittate. 8. tenuifolium has the three dorsal ridges not 

 excurrent, often subobsolete, and is therefore hardly different from Angelica. Pim- 

 pinella sikkimensis (p. 685) was referred to Selinum by Bentham. 



1. S. striatum, Benth. in Gen. PL i. 914; ultimate segments of the 

 leaves | in. narrowly oblong-lanceolate, fruit little dorsally compressed, ridges 

 subequally winged, vittae all solitary, seed about twice as broad as thick. 

 Laserpitium. striatum, Watt. Cat. 583 (not Ligusticum striatum, DC. Prodr. 

 iv. 158). 



NIPAX ; Wallich. KHASIA MTS. ; alt. 3500-6000 ft., abundant. 



Glabrous or nearly so ; 1-4 ft., frequently with many withered fibres at the base. 

 Leaves 4-8 in., ovate, 3-4-pinnate, uppermost sheath often extending the whole length 

 of the petiole. Bracts 4-6, f in., linear: ray^ glabrous or obscurely pubes- 

 cent ; bracteoles 4-8, \ in., linear, minutely white on the margin, hardly serrate, 

 not divided. Calyx-teeth linear, oblong, twice as long as broad. Fruit | in., 

 lateral furrows 1-vittate, vittae twice as wide as those in the dorsal; commis- 

 sural vittse 2, wide apart. Seed obscurely 2-grobved on the inner face. Easily 

 recognised by the little-compressed fruits and seeds. All the specimens are Khasian, 

 except Wallich's, which have the ultimate segments of the leaves less narrowly cut, 

 showing the secondary nerves impressed: the fruit is exactly as in the Khasian 

 examples. In Ligusticum striatum, DC. Prodr. iv. 158, the furrows are multi-vittate. 

 Bentham, I.e., assuming that DC. possessed the true S. striatum, points out that he 

 was mistaken on this point. But DC. also says that his Ligusticum striatum had 

 " leaves 2-pinnate the lobes acute entire seldom incised," so that his plant cannot be
