Common name: Star-anise Family.

Number of genera 1. Number of species 42.

Angiosperm. Magnoliopsida.

Disseminule a dehisced fruit, or a seed.

Fruits

Pistil(s) compound; 2–5 to 11–20; 5–20-pistillate; with carpels united. Fruit pericarpium; multiple, or simple; follicle; follicetum (Illicium verum Hook. f., Spjut Fig. 30A); without persistent central column; not within accessory organ(s); more than 1 but less than 10-seeded to 10 to less than 25-seeded; (5–)7–15(–21)-seeded; (5–)7–15(–21)-carpellate; with carpels separate; with carpels radiating at maturity; without sterile carpels; not sulcate; apex not beaked; wall leathery (we suspect heavier); dehiscent. Dehiscent unit seed(s). Dehiscent regularly; passively; linearly; by ventral sutures; at middle (assumed); and shedding seeds; without replum. Epicarp brown (all shades); durable; not glabrous (with hairs); hairs not glandular; without armature; smooth; without wing(s); without apical respiratory hole. Mesocarp absent. Endocarp present; not separating from exocarp; thin; not splitting into 1-seeded pyrenes; smooth; without wing; without operculum; without secretory cavities; without mechanism for seedling escape; without grooves; without longitudinal ridges. Funiculus short; short without seed bearing hooks (retinacula); not persisting in fruit after seed shed.

Seeds

Aril absent. Seed larger than minute; oblong, or ovate to reniform, or U-shaped; in transection compressed; not bowl shaped; not nutlike; without winglike beak; without caudate appendage(s); at maturity with food reserves; with endosperm; without canavanine. Sarcotesta absent. Testa present; without markedly different marginal tissue; without fleshy or leathery layer over hard layer; tight; shiny; surface unsmooth; surface with merged raised features; surface reticulate; without crease or line separating cotyledons from hypocotyl-radicle; without notch along margin where cotyledons from hypocotyl-radicle tip approach each other; without glands; without bristles; glabrous; without wings; without collar; without operculum; colored; monochrome; brown (all shades), or black; thin; not becoming mucilaginous when wetted. Raphe conspicuous; included in dehisced fruit. Endosperm development cellular, or nuclear; copious; fleshy; transparent; smooth; with oils; without fatty acid containing cyclopropene; without apical lobes; without chlorophyll; without isodiametric faceted surface; without odor.

Embryo differentiated from food reserve (but minute); well developed; 1 per seed; nearly filling testa (trace or scanty food reserve); 0.06–0.1 times the length of food reserve; at one end of seed not extending into a depression or cup; axile and centric; linear; straight; parallel to seed length; with cotyledons gradually connected to hypocotyl-radicle; without coleorhiza; without simmondsin; without stomata; not green; with 2 or more cotyledons. Cotyledons 2; tiny, or moderately developed (really 2–4); 0.1–0.5 times length of embryo; as wide as hypocotyl-radicle; 1 times wider than hypocotyl-radicle; not concealing hypocotyl-radicle; not foliaceous; thin; flat; smooth; with apices entire; with margins separate; basally entire; equal in size; not punctate dotted. Hypocotyl-radicle small; straight; not thickened.

We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key, which allows access to the character list, illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa. See also Guidelines for using data taken from Web publications.
