PUNJAB ; Edgeworth, Vicary, Altcheson. SCINDE ; Stocks. DISTHIB. Aden, Nubia. 



Subprostrate, glandular-puberulous or glabrate ; branches 8-18 in., much 

 divided. Leaves - in., opposite or nearly so petiole in. Cymes sessile (or nearly 

 so) at the nodes. Sepals in., roundish. Petals much shorter than the sepals, obovate, 

 clawed, the upper margin incised or nearly fimbriate. Stamens 6-7 (Oliver). Carpels 

 in fruit as long as the sepals, hemispheric, dehiscing ventrally; margins of the 

 valves inflexed so as to retain the seed until moistened. Seed reniform, longer than 

 broad, compressed, concavo-convex, perfectly smooth, whitish. 



ORDER LXX. U1VIBELLIFERJE. (By 0. B. Clarke.) 



Herbs (rarely in non-Indian species shrubs or trees). Leaves alternate, 

 usually divided or dissected, sometimes simple, petiole generally sheathing at 

 the base ; stipules 0. Flowers hermaphrodite or polygamous, in compound umbels 

 (simple in Hydrocotyle and Bupleurum), exterior of the umbel sometimes 

 radiant ; umbels with involucriform bracts at the base of the general one and 

 bracteoles at the base of the partial ones (umbellules). Calyx-tube adnate to 

 the ovary, limb or 5-toothed. Petals 5, epigynous, often unequal, and with 

 a median fold on the face, plane or emarginate or 2-lobed with the apex 

 inflexed ; imbricated in bud, in Hydrocotyle sometimes valvate. Stamens 5, 

 epigynous. Ovary inferior, 2-celled, disc 2-lobed ; styles 2, stigmas capitellate ; 

 ovules 1 in each cell, pendulous. Fruit of 2 indehiscent dorsally or laterally 

 compressed carpels, separated by a commissure ; carpels each attached to and 

 often pendulous from a slender often forked axis (carpophore), with 5 primary 

 ridges (1 dorsal, 2 marginal and 2 intermediate) and often 4 secondary ones 

 intercalated between these ; pericarp often traversed by oil canals (vittse). Seed 

 1 in each carpel, pendulous, albumen cartilaginous ; embryo small, next the 

 hilum, radicle superior. DISTRIB. Species 1,300, mainly in Europe, North 

 Africa, West Central and North Asia; a few are North American, tropical, and 

 natives of the Southern Hemisphere. 



Tordylium is stated in Gen. PI. i. 871 to be Himalayan. We have seen no spe- 

 cimens. 



An umbellifer in flower, Edgw. No. 175 from the North-west Himalaya, alt. 

 6000-7000 ft, may be Johrenia alpina, Fenzl.
