Crepis monticola


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: CrepisView DescriptionDichotomous Key


Common Name: HAWKSBEARD
Habit: Annual to perennial herb from taproot, woody caudex, or creeping rhizome; sap milky. Stem: 1--20+, erect, <= 12 dm, simple or branched, glabrous to densely hairy, sometimes stalked-glandular. Leaf: generally basal and cauline, alternate, base narrowed, often winged, blade entire or toothed to pinnately lobed or divided. Inflorescence: heads liguliflorous, generally in cyme-like, flat-topped, or panicle-like clusters; phyllaries in 2 series, outer reduced, inner +- equal, abaxially glabrous or hairy, adaxially generally glabrous; receptacle flat to convex, epaleate, shallowly pitted. Flower: 5--100+; corolla generally yellow [orange, white, pink], generally glabrous; ligule readily withering. Fruit: +- cylindric or fusiform, distally +- tapered or beaked with +- distinct constriction, 10--20-ribbed, glabrous or minutely short-rough hairy; pappus of 80--150 soft, hair-like bristles.
Species In Genus: +- 200 species: especially northern hemisphere. Etymology: (Greek: slipper or sandal, perhaps for fruit) Note: Reports of Crepis rubra L. from Marin Co. not substantiated.
Unabridged Note: Sexual forms of native species are distinct but (except Crepis nana, Crepis runcinata) connected by many apomictic, asexually reproducing forms of hybrid origin that obscure boundaries. Many of these asexual forms were grouped into subspecies by Babcock and Stebbins (1947); however, it is doubtful that these will hold up under close taxonomic scrutiny.

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.
