Description

Family Apiaceae

Herbs, annual or perennial , rarely woody at base . Caulescent or acaulescent , stem hollow or solid. Leaves alternate, rarely opposite or basal; petiole usually sheathing at base; stipules absent (except in subfam. Hydrocotyloideae) ; leaf blade compound or sometimes simple , usually much incised or divided , pinnatifid to pinnatisect , or ternate-pinnately decompound . Flowers epigynous , small, bisexual or staminate (unisexual male), regular, in simple or compound umbels; umbellules few to many-flowered; rays often subtended by bracts forming a involucre; umbellules (sometimes called umbellets ) usually subtended by bracteoles forming an involucel . Pedicels long, short or obsolete (then forming a capitate umbellule) . Calyx tube wholly adnate to the ovary; calyx teeth (sometimes called sepals) small or obsolete, forming a ring around the top of the ovary. Ovary inferior, 2-celled, with one anatropous ovule in each locule. Styles 2, usually swollen at the base forming a stylopodium which often secretes nectar. Fruit dry, of two mericarps united by their faces (commissure ), and usually attached to a central axis (carpophore), from which the mericarps separate at maturity; mericarps are variously flattened dorsally , laterally or terete ; each mericarp has 5 primary ribs , one down the back (dorsal rib), two on the edges near the commissure (lateral ribs ), and two between the dorsal and lateral ribs (intermediate ribs), occasionally with four secondary ribs alternating with the primary , the ribs filiform to broadly winged , thin or corky; vittae (oil-tubes) usually present in the furrow (intervals between the ribs sometimes called the valleculae) and on the commissure face, rarely also in the pericarp, sometimes obscure . Each mericarp 1-seeded, splitting apart at maturity. Seed face (commissural albumen) plane , concave to sulcate .

Between 250 and 440( 455) genera and 3300 3700 species: widely distributed in the temperate zone of both hemispheres, mainly in Eurasia and especially in C Asia; 100 genera (ten endemic) and 614 species (340 endemic) in China.[1]

Genus Aegopodium

Herbs, perennial , essentially glabrous . Stem erect , branching above or simple . Basal and lower leaves petiolate , sheaths broad, membranous; blade broadly triangular to triangular in outline, ternate or ternate-2-3-pinnate; ultimate segments ovate or ovate-lanceolate, serrate, dentate-divided or lobed . Upper leaves reduced, usually ternate-pinnate. Umbels compound , terminal and lateral ; peduncles longer than the leaves; bracts and bracteoles usually absent; rays ascending-spreading. Calyx teeth obsolete . Petals white or pinkish, obovate , apex with narrow inflexed lobule . Stylopodium conic; styles long, reflexed . Fruit oblong , oblong-ovoid or ovoid , slightly flattened laterally, glabrous; mericarp subrounded in cross section ; ribs filiform , prominent to obscure ; vittae inconspicuous. Seed face plane . Carpophore bifid at apex.

About seven species: Asia, Europe; five species (two endemic) in China.[2]
