the carpels not readily separating, the ribs scarcely prominent, and no 



vittEe. 



The genus consists of a single species. 



1. C. sativum^ Linn. ; DC. F?'od.iv.250 ; JFif/Id, Ic.t.^lQ. An erect, 

 branching, glabrous annual, 1 to 1^ ft. high, emitting a very disagreeable 

 smell when rubbed. Lowest leaves once or twice pinnate, with broadly ovate 

 or cuneate deeply cut segments ; the others more divided, with linear seg- 

 ments, few and slender in the uppermost. Umbels teiminal, rather smaE, of 

 5 to 8 rays, without general involucre, and only a few slender bracts to the 

 partial ones. Flowers white. Fruits about 2 lines diameter. 



In waste places, Jlance and others. A native of the Levant, and introduced by cultiva- 

 tion, has now spread as a weed over a great part of Europe and Asia. 



OiiDER LIL ARALIACE^. 



Calyx combined with the ovary, either enth-ely so or showing a minute 

 border round the summit, with as many teeth as petals. Petals usually 4 or 5, 

 or rarely more, valvate or rarely imbricate in the bud, inserted round an 

 epigynous disk, or sometimes none. Stamens as many, alternating with the 

 petals. Ovary inferior, 2- to 5- or more celled, with one pendulous ovide in 

 each cell. Styles as many as cells, usually short, and sometimes united into 

 one or reduced to a small cone, stigmatic at the top. Fruit not readily sepa- 

 rating into cai-pels, indehiscent, and usually succulent. Seeds solitaiy in 

 each cell. Embiyo minute, in a fleshy albumen. — Trees, shrubs, or climbers, 

 or very rarely herbs. Leaves simple or compound. Flowers usually small, 

 in heads or simple umbels, which are either solitaiy or arranged in racemes 

 or panicles. 



A considerable Order, chiefly tropical, with a very few species extending into more tem- 

 perate regions, both in the New World and the Old.

1. ARALIA, Linn. 



Flowers polygamous. Umbels paniculate. Calyx distinctly 5-toothed. 

 Petals 5, imbricate in the bud. Styles 2 to 5, free. Berry 2- to 5 -celled.— 

 Trees, shrubs, or herbs. Leaves decompound, usually twice or tlnice pinnate, 

 very rarely digitate. 



A small genus, dispersed over North America and eastern Asia. 



1. A. chinensis, Linn. ; DC. Prod. iv. 259. A tree, with the brandies, 

 leaves, and inflorescences more or less villous, and armed with scattered prickles. 

 Leaves twdce or three times pinnate, usually with 7 to 9 piniia% and 7 to 11 

 leaflets on each, or some of these replaced by a secondary pinna of 3 or 5 

 leaflets. Leaflets nearly sessile on the common stalks, ovate-cordate or ovate- 

 lanceolate, simply or doubly serrate, about 1^ in. long, often oblique at the 

 base. Flowers 20 to 30 or more in each umbel ; the umbels peduncidate, on
