David J. Keil, except as noted

Annual to tree. Leaf: basal and/or cauline, alternate, opposite, rarely whorled, simple to 2+ × compound. Inflorescence: 1° inflorescence a head, resembling a flower, of several types (see below), 1–many in generally ± cyme-like cluster; each head generally with ± calyx-like involucre of 1–many series of phyllaries (involucre bracts); receptacle of head flat to conic or columnar, paleate (bearing paleae = receptacle bracts) or epaleate; flowers 1–many per head. Flower: bisexual, unisexual, or sterile, ± small, of several types (see below); calyx 0 or modified into ± persistent pappus of bristles, scales, and/or awns; corolla radial or bilateral (0), lobes generally (0)3–5; stamens 4–5, filaments generally free, generally fused to corolla at tube/throat junction, anthers generally fused into cylinder around style, anther base generally rounded or cordate (deeply sagittate or with tail-like appendages), tip (= flattened appendage) generally projecting beyond pollen sac; pistil 1, 2-carpeled, ovary inferior, 1-chambered, 1-seeded, placenta basal, style 1, tip generally ± 2-branched (except in some staminate disk flowers), branch tips truncate or generally bearing ± brush-like appendages; stigmas 2, generally on adaxial faces of style branches. Fruit: achene (also called a cypsela) (drupe in Chrysanthemoides), cylindric to ovoid, sometimes compressed, generally deciduous with pappus attached.
± 1500 genera, 23000 species: worldwide, many habitats. Flower and head types differ in form and sexual condition. A disk flower has a generally radial corolla, with a cylindric tube, expanded throat, and generally 5 lobes. Disk flowers are generally bisexual and fertile but occasionally staminate with reduced ovaries. Discoid heads comprise only disk flowers. A radiant head is a variant of a discoid head, with peripheral disk flower corollas expanded, often bilateral. A ray flower corolla is bilateral, generally with a slender tube and flattened petal-like ray (single lip composed of generally 3 lobes). Ray flowers are generally pistillate or sterile (occasionally lacking styles). Radiate heads have peripheral ray flowers and central disk flowers. Disciform heads superficially resemble discoid heads, with pistillate or sterile flowers that lack rays, together with or separate from disk flowers. A ligulate flower is bisexual, with a bilateral, generally ephemeral corolla and 5-lobed ligule. Liguliflorous heads comprise only ligulate flowers. See glossary p. 31 for illustrations of family characteristics. Echinops sphaerocephalus L., Gaillardia aristata Pursh, Gaillardia pulchella Foug., Hymenothrix loomisii S.F. Blake, Tagetes erecta L., Thelesperma megapotamicum (Spreng.) Kuntze are waifs. Melampodium perfoliatum Kunth, historic urban waif. Ageratum conyzoides L., Guizotia abyssinica (L. f.) Cass., Santolina chamaecyparisus L., orth. var. are rare or uncommon escapes from cultivation. Dyssodia papposa, Ismelia carinata (Schousb.) Sch. Bip. [Chrysanthemum carinatum Schousb.], Mantisalca salmantica (L.) Briq. & Cavill. are historical or extirpated waifs in California. Inula helenium L. not documented in California.

Key to Asteraceae

Shrub. Stem: generally several from base. Leaf: simple, alternate or opposite, sessile or petioled. Inflorescence: heads radiate, 1 or in few-headed cyme-like clusters; peduncles long or short; involucre hemispheric or bell-shaped; phyllaries in 2–3 series, generally unequal; receptacle convex, paleate; paleae entire or 3-lobed, folded around fruits. Ray flower: 8–15, sterile; corolla yellow; ray entire to 3-lobed. Disk flower: many; corolla yellow or orange; anther tips triangular; style tips triangular. Fruit: ± flattened, obovate, ± strigose, brown to black; pappus of scales, generally 2 longer, ± lanceolate, (0)2–6 shorter, readily-deciduous.
12 species: southwestern United States, northwestern Mexico. (Greek: like Bahia, an Asteraceae genus) [Schilling 2006 FNANM 21:174–176] Bahiopsis tomentosa (A. Gray) E.E. Schill. & Panero collected twice in southern South Coast in early 1900s, probably an escape from cultivation.
Unabridged references: [Schilling & Panero 2002 Bot J Linn Soc 140:65–76]
Unabridged note: The two early California collections of Bahiopsis tomentosa (A. Gray) E.E. Schill. & Panero [not included in TJM (1993)] were from San Diego Co. Their status as escapes from cultivation is based on a 1933 annotation by SF Blake w/ref. to Zoe 5:260. [San Diego, 14Apr1906, M.E. Jones s.n., POM; slope near La Jolla, 300 ft., Sep 1919, M.E. Spencer 1644, POM]. Bahiopsis tomentosa is otherwise known from Baja California Sur.

B. parishii (Greene) E.E. Schill. & Panero PARISH'S GOLDENEYE
Plant <= 2 m diam, short-rough-hairy throughout. Stem: 6–13 dm, much-branched. Leaf: proximal opposite, distal alternate; petiole 2–8 mm; blade generally 1–3.5 cm, triangular-ovate, 3-veined from obtuse to truncate or ± cordate base, tip obtuse to acute, margin entire or often few-toothed, faces green to lightly canescent. Inflorescence: heads 1 or in open, few-headed cyme-like clusters; peduncle 3–15 cm, slender, bracts 0 or few and leaf-like; involucre 10–13 mm diam, hemispheric or appearing disk-like when pressed; phyllaries equal or unequal, 3–9 mm, lance-oblong, green to canescent, tips abruptly narrowed; paleae 5–6 mm. Ray flower: 8–15; ray 1–1.5 cm. Disk flower: corolla 3.5–5 mm. Fruit: 2.7–3.8 mm; long pappus scales 2–3 mm, short scales 0.5–1 mm.
