Lefebvrea A.Rich.

Biennial or perennial herbs, glabrous or almost so; rootstock fusiform to subdigitately branched or tuberous. Leaves simply to subtripinnate, trisect or biternate (rarely simple); segments linear and entire to broad and jaggedly toothed, with a strong midrib and a parallel longitudinal nerve on each side between the midrib and the margins, these nerves distinct in narrow-leaved forms, more irregular in broad-leaved forms even of the same species but still detectable as they zigzag upwards towards the apex and anastomose, with subsidiary nerves. Involucre absent or of up to ± 8 filiform bracts; involucel of up to ± 8 filiform bracteoles; flowers usually polygamous in a similar manner to those of Peucedanum. Calyx obsolete. Petals creamy, yellowish or greenish, sometimes suffused with brown or purple, ± incised above with an incurved tip. Fruit strongly dorsally compressed, broadly elliptic or obovate to roundish, glabrous, truncate or almost so at the base, deeply incised at the apex with rounded, incurved auricles overtopping the stylopodia, commissure wide; 3 dorsal ribs plane or slightly prominent, 2 marginal ribs expanded into broad, thin wings; vittae 2–4 on the commissural face, solitary in the valleculae, all black and conspicuous; stylopodia elongate or shortly conical or cylindrical-clavate and obtuse; styles short; carpophore deeply bipartite. Endosperm ± flat or somewhat bisulcate on the commissural face, slightly to deeply sulcate beneath the vittae dorsally.
