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.

Common Name: BRICKELLBUSH
Habit: [Annual] perennial herb to shrub. Leaf: simple, alternate or opposite, generally resinous-dotted, veiny, main veins generally 3. Inflorescence: heads discoid, generally clustered; involucre cylindric to bell-shaped; phyllaries generally graduated, +- green, veiny-striate, spreading in age; receptacle generally flat, epaleate. Flower: corolla cylindric, +- white to pale yellow-green, occasionally tinged red or purple; anther tip ovate; style branches long, club-shaped, tips rounded. Fruit: 10-ribbed, generally cylindric, generally hairy; pappus of 10--40+ generally minutely barbed bristles, generally white.

Brickellia nevinii A. Gray
NATIVE
Habit: Shrub 30--80 cm. Stem: much-branched near base, tomentose, gland-dotted. Leaf: alternate, petiole 0--1 mm, blade 7--11 mm, 3--8 mm wide, ovate to cordate, dentate-serrate, base rounded to +- cordate, tip obtuse, faces tomentose, main veins 3--5, obscure. Inflorescence: heads at long-branch tips, in panicle-like clusters; peduncle 1--5 mm, tomentose; involucre 10--12 mm, cylindric to top-shaped; phyllaries 30--38, in 7--9 series, often red- or +- purple-tinged, 3--6 striate, recurved, tomentose, gland-dotted, tip acute to acuminate, margin scarious, ciliate; outer lance-ovate, inner lanceolate. Flower: 16--24; corolla 6.2--7.5 mm, pale yellow or cream, often purple-tinged. Fruit: 3.5--5 mm, minutely bristly; pappus bristles 18--24, white or tawny. Chromosomes: 2n=18.
Ecology: Rock crevices, rocky slopes, desert scrub; Elevation: 300--1900 m. Bioregional Distribution: SCoRI, WTR, SnGb, DMoj; Distribution Outside California: Nevada. Flowering Time: Aug--Nov
Unabridged Note: Brickellia nevinii appears to be a gray-hairy form of Brickellia microphylla. The variability in hairiness often makes distinguishing these species problematic, particularly in areas of San Bernardino and Inyo cos. Brickellia nevinii, perhaps, should be recognized as a variety of Brickellia microphylla. It is reported to intergrade with Brickellia californica in mixed populations of the coast range. Work on this sp. is on-going.
