Leaf: simple, cauline, sometimes also basal, opposite or whorled, entire, sessile or basal +- petioled; stipules 0. Flower: bisexual, radial, parts in 4s or 5s except pistil 1; sepals fused, persistent; petals fused, +- persistent, sinus between lobes often unappendaged; stamens epipetalous, alternate corolla lobes; ovary superior, chamber 1, placentas parietal, often intruding, stigmas 1--2. Fruit: capsule, 2-valved. Seed: many.
Genera In Family: +- 90 genera, 1800 species: worldwide; some cultivated (Eustoma, Exacum, Gentiana). Note: Gentianella tenella moved to Comastoma. Key to genera revised by Bruce G. Baldwin.

Genus: CentauriumView DescriptionDichotomous Key

Common Name: CENTAURY
Habit: Annual, biennial, glabrous. Stem: erect, branched or simple below inflorescence. Leaf: cauline, opposite, also basal or not. Inflorescence: cyme. Flower: parts generally in 5s; calyx lobes >> tube (discounting thin membrane between lobes in Centaurium tenuiflorum), +- appressed to corolla tube; corolla salverform, generally pink, lobes < tube, elliptic-oblong, entire or minutely toothed at tip, scales 0, nectary pits 0 (nectaries elsewhere 0); stamens initially curved to 1 side, dehisced anthers spirally twisted; ovary sessile, style thread-like (much wider than filaments), cleft 0.5--1 mm, deciduous, stigmas 2, elliptic to ovate.
Species In Genus: +- 15 species: temperate, dry-mesic tropics, +- Eurasia, northern Africa, Mexico. Etymology: (Latin: centaur, mythological discoverer of plants medicinal properties) Note: Native species moved to Zeltnera.

Centaurium pulchellum (Sw.) Hayek ex Hand.-Mazz., Stadlm., Janch. & Faltis
WAIF
Habit: Annual, 2--25(30) cm. Leaf: basal not rosetted, 5--25 mm, obovate to oblong; cauline 5--15(25) mm, lower elliptic-oblong, upper lanceolate. Inflorescence: open, generally not flat-topped; pedicels 1--5(11) mm. Flower: corolla lobes 2--5 mm. Chromosomes: 2n=36.
Ecology: Moist fields, roadsides; Elevation: +- 60 m. Bioregional Distribution: SnJV; Distribution Outside California: to Washington, eastern United States; native to Eurasia. Note: A few plants reported in 2012 from a qualifying habitat (coastal sage scrub) in South Coast (San Diego Co.), with no evidence of having been planted; additional reports of such populations elsewhere in the state and/or confirmation that the reported population has persisted would qualify the species as naturalized.
