Deinandra minthornii

Higher Taxonomy
Family: Asteraceae (Compositae)View DescriptionDichotomous Key
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.)

[Chrysanthemum carinatum Schousb.], Mantisalca salmantica (L.) Briq. & Cavill. are historical or extirpated waifs in California. Inula helenium L. not documented in California.

Genus: DeinandraView DescriptionDichotomous Key

Habit: Annual [perennial herb] or subshrub to shrub, 4--120(150) cm, generally aromatic. Stem: generally +- erect, generally +- solid. Leaf: proximal in basal rosette or opposite (generally not persistent), most alternate, sessile, linear to lanceolate or oblanceolate, proximal generally pinnately lobed to serrate, distal generally entire, hairy, often glandular. Inflorescence: heads radiate, generally in flat-topped or +- panicle-like clusters or in tight groups; involucre bell- or urn-shaped, hemispheric, or +- obconic, 2--13+ mm diam; phyllaries 3--35 in 1 series, +- linear to lanceolate or oblanceolate, each generally 1/2 enclosing a ray ovary, falling with fruit, +- hairy and sessile- or stalked-glandular; receptacle flat to convex, glabrous or minutely bristly; paleae in 1 series between ray and disk flowers in annual or in 2--3+ series or subtending all or most disk flowers in shrubs, fused or free, phyllary-like, more scarious. Ray Flower: 3--35; corolla deep or pale yellow. Disk Flower: 3--70, generally staminate, sometimes bisexual; corolla yellow, tube <= throat, lobes deltate; anthers generally +- red to dark purple or yellow to brown, tips lance-ovate to deltate; style glabrous proximal to branches, tips awl-shaped, densely bristly.; anther bases cordate-sagittate to sagittate. Fruit: ray nearly round in ×-section (except +- flattened adaxially) or +- 3-angled (abaxially generally +- widely 2-faced, adaxially +- flattened to slightly bulging), generally +- arched, glabrous, tip +- beaked, beak offset adaxially, ascending, pappus 0; disk fruit generally 0, disk pappus generally of 1--15 generally linear to lanceolate, entire or fringed to deeply cut scales, sometimes 0 or crown-like.
Etymology: (Greek: fierce man, probably for name it replaced, Hartmannia DC., meaning "stag man," stags being fiercely territorial) Note: Self-sterile except Deinandra arida and Deinandra mohavensis.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
