Root, in a state of cultivation, forming large oblong 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 inter, mostly terminal, small, compound. Jnvolucres 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 ais depressed gland are extremely imperfect. The her- 
edieg the circumference, and have 5 nearly equal, 
i d acumen, 
curved, Anthers roundish, somewhat 2-lobed. Germen ovate, with 10 
Strie. Styles 2, erect, afterwards curved outwards, their bases slightly
