Agoseris aurantiaca var. aurantiaca

Higher Taxonomy
Family: Asteraceae (Compositae)View DescriptionDichotomous Key

Common Name: SUNFLOWER FAMILY
Habit: 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.
Genera In Family: +- 1500 genera, 23000 species: worldwide, many habitats. Note: 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.

Genus: AgoserisView DescriptionDichotomous Key

Habit: Annual or perennial herb from taproot, occasionally with branched caudex, generally scapose; sap milky. Leaf: generally all basal, generally lanceolate to oblanceolate, long-tapered to obtuse, entire, toothed, or 1--2-pinnately lobed, 1° lobes generally +- opposite, generally on proximal 2/3; 2° lobes 0--1; faces glabrous to densely hairy, hairs generally white-opaque and glandless. Inflorescence: heads liguliflorous, 1, erect, long-peduncled; involucre cylindric to ovoid or bell-shaped in flower, ovoid in fruit, glabrous to densely hairy, hairs white-opaque and glandless or colorless- or yellow-translucent (occasionally with purple cross-walls) and glandular, glands generally yellow, occasionally purple; phyllaries in 2--5(+) series, +- equal in flower, often strongly graduated in fruit, generally entire, green to rosy-purple, often with darker spots or midstripe, outer erect or tips spreading to recurved, inner erect, elongating with fruit or not, +- reflexed when dry; receptacle flat, epaleate (paleate), generally pitted. Flower: 5--500; ligules +- equaling to much exceeding involucre, yellow, or orange, pink, red, or purple, readily withering. Fruit: cylindric to fusiform or obconic (inflated), +- 10-ribbed, generally +- white to brown or purple-black (gray), glabrous to minutely coarse-hairy or puberulent; beak << to >> body (0); pappus of many fine, simple, white bristles.
Species In Genus: 11 species: America. Etymology: (Greek: chief or goat + chicory, meaning is obscure) Note: Closely related to Nothocalais. Self-pollination complicates variation in some species; polyploidy and hybridization blur distinctions between some taxa.
