ASTERACEAE

SUNFLOWER FAMILY

David J. Keil, Family Editor and author, except as specified

Annual to tree
Leaves basal or cauline, alternate to whorled, simple to compound
Inflorescence: 1° inflorescence a head, each resembling a flower, 1–many, generally arrayed in cymes, generally subtended by ± calyx-like involucre; flowers 1–many per head
Flowers bisexual, unisexual, or sterile, ± small, of several types; calyx 0 or modified into pappus of bristles, scales, or awns, which is generally persistent in fruit; corolla radial or bilateral (rarely 0), lobes generally (0)4–5; stamens 4–5, anthers generally fused into cylinder around style, often appendaged at tips, bases, or both, filaments generally free, generally attached to corolla near throat; pistil 1, ovary inferior, 1-chambered, 1-seeded, style 1, branches 2, generally hair-tufted at tip, stigmas 2, generally on inside of style branches
Fruit: achene, cylindric to ovoid, generally deciduous with pappus attached
Genera in family: ± 1300 genera, 21,000 species (largest family of dicots): worldwide. Largest family in CA. Also see tribal key to CA genera: Strother 1997 Madroño 44(1):1–28. See glossary p. 25 for illustrations of general family characteristics.

HELIOMERIS

GOLDEN-EYE

Annual, perennial herb
Stems 1–many from base, slender, spreading or erect
Leaves simple, opposite or upper alternate, linear to narrowly elliptic, entire
Inflorescence: heads radiate, solitary or in few-headed cymes; peduncles slender, bracts 0–few, linear; involucre hemispheric, appearing disk-shaped when pressed; phyllaries in 2–3 ± equal series, linear; receptacle conic, chaffy, scales linear-lanceolate
Ray flowers sterile; corollas yellow-orange; ligules showy, oblong, entire or nearly so
Disk flowers many; corollas yellow-orange; style tips triangular
Fruit oblanceolate, ± 4-angled, flat, glabrous; pappus 0
Species in genus: 6 species: North America
Etymology: (Greek: sun part, from showy heads)

YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).
