Description

Family Compositae

The largest family of flowering plants , the Compositae (Asteraceae), comprising about 1,100 genera and more than 20,000 species and characterized by many small flowers arranged in a head looking like a single flower and subtended by an involucre of bracts. A head may consist of both ray flowers and disk flowers, as in the sunflower, of disk flowers only, as in the burdock, or of ray flowers only, as in the dandelion.

Genus Madia

Annuals , 5-250 cm. Stems erect . Leaves mostly cauline (at flowering) proximal opposite (often in rosettes), distal alternate; sessile; blades lanceolate or oblong-linear to linear , margins usually entire, sometimes toothed , faces hirsute to strigose , usually glandular-pubescent as well. Heads usually radiate (sometimes discoid in M. glomerata), in corymbiform , paniculiform , racemiform , or spiciform arrays or in glomerules . Peduncular bracts: pit-glands, tack-glands, and/or spines 0. Involucres ellipsoid , depressed-globose, globose , obconic, ovoid , or urceolate , 1-10+ mm diam. Phyllaries 0 (then outer paleae functioning as phyllaries, sometimes in M. glomerata), or 1-22 in 1 series (lance-linear to lance-attenuate or oblanceolate , herbaceous, each mostly or wholly enveloping a subtended ray ovary, abaxially hirsute and, usually, glandular ). Receptacles flat to convex , glabrous or setulose , paleate (paleae persistent or falling readily, in 1 series between rays and discs, ± connate or distinct , phyllary-like, more scarious ). Ray florets 0 (sometimes in M. glomerata), or 1-22, pistillate , fertile ; corollas yellowish (with maroon bases sometimes in M. elegans; purplish red sometimes in M. sativa). Disc florets 1-80+, bisexual and fertile or functionally staminate ; corollas usually yellow, sometimes purplish, tubes shorter than or about equaling funnelform throats , lobes 5, deltate (anthers ± dark purple or yellow to brownish; styles glabrous proximal to branches). Ray cypselae compressed , ± 3-angled, or rarely terete , clavate (often arcuate , basal attachments central or offset , apices sometimes beaked , faces glabrous) ; pappi 0. Disc cypselae similar, sometimes obovoid (often ± straight, basal attachments central, apices not beaked), sometimes 0; pappi 0. x = 8.

Species 10: North America, South America, Pacific Islands (Hawaii, probably introduced ).[1]
