Root, in a state of cultivation, forming large ue tubers, often as large as 
that of the carrot. Stem a foot and a half or more in height, branched — 
above, terete, striated, glabrous, leaves glabrous, the lower ones upon — 
very long, striated footstalks, sheathing at the base, pinnated with 5 broad- 
ly ovate, acuminated pinne, pinnatifid, cut and deeply and irregularly 
serrated at the margin: of these pinne, the uppermost one is more or _ 
less petiolated and subternate. Upwards upon the stem, the leaves 
become gradually smaller, more simple, and with shorter petiols, till at 
length the uppermost ones are almost sessile, trifid or tripartite, and 
acutely serrated ; and all of them nerved and veined. 
Umbels rarely lateral, mostly terminal, small, compound. JInvolucres none. 
Partial ones few, small, subulate, about 3. Rays 10-12. Flowers on 
short pedicels; abortive ones nearly sessile, occupying the centre of the 
partial umbels. These are of two kinds: some bear perfect stamens, 
and differ from the perfect flowers in having no pistil, and only a small 
depressed superior disk or gland; others are altogether imperfect, very 
small: their petals never expand (see Fig. 1.), and the stamens which — 
surround a small depressed gland are extremely imperfect. The her-- 
maphrodite flowers occupy the circumference, and have 5 nearly equal, 
spreading, inversely heart-shaped petals, with an incurved acumen, 
whitish, green on the outside in the centre. Stamens 5. Filaments 
curved. Anthers roundish, somewhat 2-lobed.. Germen ovate, with 10 
strie. Styles 2, erect, afterwards curved outwards, their bases slightly 
swelling, and surrounded by a waved annulus. rut (but hardly ripe)
