pinnatifid

Leaves all divided deeply or at least to middle, sometimes deep lobes pinnatifid, some lobes broad and undivided.

The typical leaf is pinnatifid, tapering gradually to a stout petiole and becoming broader toward the large terminal lobe.

Basal leaves petiolate, somewhat fleshy, rosulate or not, often withered by flowering, simple, entire or rarely toothed or pinnatifid.

Flowers unisexual and plants dioecious; fruit drupaceous; leaves simple or tripartite to pinnatifid, margin entire.

Lowermost flowers of main raceme ebracteate; basal leaves lyrate or pinnatifid, often canescent, persistent in flower and fruit.

Stem leaves alternate, lanceolate-linear to lanceolate-oblong, pinnatifid to pinnatisect.

a dainty South American annual having deeply pinnatifid leaves and racemes of fringed almond-scented purple-white flowers.

Rootstock moniliform; leaflets obovate-elliptic to elliptic, not pinnatifid.

delicate fern widely distributed in North America and European having thin pinnatifid fronds with brittle stems.

Bracteoles linear-lanceolate, margin narrow, tinged brown, apex pinnatifid.

Leaves alternate, mostly on stem, sessile, linear to linear-oblong, pinnatifid.

Roots usually several, fleshy; calyx lobes ovate to oblong, pinnatifid.

Leaves pectinate-pinnatifid, with up to 11 lobes on each side of midvein; stigma prominently 2-lobed, lobes subdecurrent.

Stem leaves opposite or whorled, ovate-lanceolate to ovate-oblong, pinnatilobate to pinnatifid.

Herbs annual or biennial. Leaves basal, pinnatifid.

6 (5) Plants usually stemless, less than 15 cm tall, unbranched; bracteoles linear to long-obovate, entire to pinnatifid.

Leaves basal and on stem, opposite, rarely in whorls of 3, lanceolate to ovate, pinnatifid to pinnatisect.

segments 5--11 pairs, widely spaced, oblong-lanceolate, often not symmetrical, margin double dentate or pinnatifid.

segments 6--9 pairs, widely spaced, ovate to linear-lanceolate, pinnatifid or incised-double dentate.

3 (2) Ultimate leaf segments oblong, margin pinnatifid or variously laciniate-dentate.

segments 5--9 pairs, widely spaced, linear to lanceolate, pinnatifid, few toothed.

segments 7--14 pairs, ovate to lanceolate, pinnatifid or double dentate.

2 (1) Leaflets 2-pinnatifid, adaxially setose on veins; styles 2, usually united into a column; seeds subglobose.

Middle cauline leaves elliptic or lanceolate, serrate, dentate, or rarely pinnatifid, (3-)5-10(-15) mm wide.

Lower and middle cauline leaves shortly petiolate, pinnatifid or pinnatisect, with oblong to linear-oblong lobes, smaller than basal leaves;

leaf margin weakly serrate to sinuate-pinnatifid, often with large terminal lobe;

leaf blade linear-lanceolate, 1. 5--6 cm, abaxially glandular pubescent, adaxially glabrous, pinnatifid or only double dentate apically;
