Description:

Annual plant. Almost bare to sparse cobwebby fibrous plant. Stems one or more, up to 40 cm high, usually branched. Leaves feathery-like divided, with spaced, obtuse, serrated shares, cobwebby fibrous; basal and lower stem leaves 2 - 8 cm long, 0.7 - 2 cm wide, back lance in outline, located on short petioles; middle and upper oblong, sessile, stem-covering, with ears at the base. Baskets numerous, 4 - 5 mm in diameter, almost sessile, gathered in dense, almost thyroid groups; the petioles of the baskets extending after flowering. The shell is 6 - 8 mm long, 3 - 4 mm wide, cylindrical. Inflorescence leaves 8 - 14, 1 - 2 mm long, 0.5 - 0.7 mm wide, ovate-lance to broadly lance, most often with a black spot on the tip, sometimes completely black, glabrous, ciliated on the tip or with a lock of hairs. Enveloping leaflets 5 - 8 mm, about 1 mm wide, linearly lance, usually glabrous, with a black spot on top. Tongue flowers usually absent, rarely 6 - 12, yellow, short, curling outwards immediately after flowering. Fruit seeds 1.5 - 2 (2.5) mm, densely fibrous between the ribs; kite 5 - 7 mm, white.

Senecio vulgaris, often known by the common names groundsel[3]:764 and old-man-in-the-spring,[4] is a flowering plant in the daisy family Asteraceae. It is an annual herb, native to Europe and widely naturalised as a ruderal species in suitable disturbed habitats worldwide.

Description

Senecio vulgaris is an erect herbaceous annual growing up to 16 inches (45 cm) tall.[3]:764 The inflorescences usually lack ray florets, the yellow disc florets mostly hidden by the bracts giving the flowers an inconspicuous appearance. Senecio vulgaris is very similar to Senecio viscosus but S. vulgaris does not have the glandular hairs and ray florets found in S. viscosus.[5]

Leaves and stems

Upper leaves of Senecio vulgaris are sessile, lacking their own stem (petiole), alternating in direction along the length of the plant, two rounded lobes at the base of the stem (auriculate) and sub-clasping above. Leaves are pinnately lobed and +2.4 inches (61 mm) long and 1 inch (25 mm) wide, smaller towards the top of the plant. Leaves are sparsely covered with soft, smooth, fine hairs. Lobes typically sharp to rounded saw-toothed.[6][7]
The hollow[8] stems branch at the tops and from the base.[6] Stems and leaves can both host the Cineraria leaf rust.[9]

Flowers

Open clusters of 10 to 22 small cylinder shaped rayless yellow flower heads ​1⁄4 to ​1⁄2 inch (6 to 13 mm) with a highly conspicuous ring of black tipped bracts at the base of the inflorescence as is characteristic of many members of the genus Senecio.[6] There is a radiate form of Senecio vulgaris, which is the result of cross pollination with the closely related Oxford ragwort, Senecio squalidus.[10]
