Common Names in English:
Sticky Groundsel, Sticky Ragwort
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.
The Senecioneae are a tribe of closely related genera that can be recognized most readily by the nature of the pappus and the involucral bracts or phyllaries. The phyllaries are basically in one well developed, often partially or wholly connate series of equal length that closely envelope the head . Frequently there are a few, very much smaller and mostly randomly distributed, often necrotic-tipped bracts near the base of the main series. The pappus is of fine, soft, often pure white capillary hairs . Heads may be either discoid or radiate . -- Gerald Carr.

The concept of Senecio in traditional North American floristics stems from nineteenth century botanists who saw the genus as a diverse assemblage held together by similar morphologies of the heads and florets . Studies in the past two decades have shown Senecio in the broad sense to be a collection of separate lineages ; a better taxonomy is to be had by treating the lineages as genera. Some of the lineages were recognized in the past as infrageneric assemblages. A treatment of Senecio by T. M. Barkley (1978) reflected the traditional circumscription of the genus; a narrower circumscription is used here. Present concepts, plus a catalogue of genera, were presented by Barkley (1999) .The "species-groups" recognized here are given names purely as a matter of convenience; the groups and their names are intentionally given no formal taxonomic status (T. M. Barkley 1978) . Some of the groups may represent natural evolutionary alliances ; that remains to be clarified.The following taxa are not established members of the flora but are nonetheless noteworthy:Senecio brasiliensis (Sprengel) Lessing var. tripartitus (de Candolle) Baker is a South American weed of disturbed sites, introduced on the Gulf Coast near Pensacola, Florida, in 1893-1894. Its presence was discussed by J. M. Greenman (1917) and by L. J. Uttal (1982), both of whom treated it as Senecio canabinaefolius Hooker & Arnott. It is toxic to livestock; it seems not to have persisted in the flora.Senecio bicolor (Willdenow) Viviani (S. cineraria de Candolle) is one of the plants called "dusty miller" in the horticultural trade. It occasionally persists in the flora after cultivation.Species of the African genus Euryops are commonly cultivated in California and Florida and, to a lesser extent, in other warm areas of the flora. They would key here to Senecio. They are shrubs with leaves dissected or prominently toothed, phyllaries connate for the proximal third of their lengths , and yellow corollas. Apparently none persist for long after cultivation.Relatively recent collections from low-lying (50-100 m ), seasonally wet, disturbed areas in Orange and San Diego counties, California, have included semi-weedy perennial herbs or subshrubs 100-200 cm that are initially arachnose to tomentose, soon glabrescent, and have oblanceolate to linear or filiform leaves (2-7 cm), notably small heads in corymbiform arrays, ± 13 phyllaries 3-4 mm, and 7-8 ray florets with corolla laminae 2-3 mm. G. L. Nesom (pers. comm. ) has suggested that these plants are Senecio linearifolius A. Richard, a native of Australia and Tasmania.References to shapes, sizes, bases, margins, induments , etc. , of "leaves" in keys and descriptions refer to principal (largest, most conspicuous ) leaves at flowering unless otherwise indicated.
Species Senecio viscosus
Annuals , (10-) 20-40(-60) cm (taprooted). Herbage densely fetid-viscid (hairs glandular ). Stems single. Leaves evenly distributed; petiolate ; blades obovate to oblong (pinnately dissected to pinnatifid ), 2-7 × 1.5-4 cm, bases tapered or ± truncate , ultimate margins wavy or crenate-dentate (distal leaves sessile, smaller, ± clasping ). Heads (1-) 3-8(-30) in irregular, corymbiform arrays. Calyculi of 2-5 bractlets (largest to 4 mm). Phyllaries (± 13) ± 21, 5-7 mm, tips black. Ray florets ± 13; corolla laminae 1-2 mm (usually coiled , scarcely surpassing phyllaries). Cypselae usually glabrous , sometimes hairy . 2n = 40. [source]
