Ivy-Leaf Senecio is a perennial herb with Ivy-like
lobed leaves and yellow flower-heads borne in penduous spikes. Stems
are solitary, erect or curved, 40-90 cm tall, grooved, simple,
synflorescence branched above, hairless. Lower leaves fall off by
flowering time; stem leaves many, 5-8. Median leaves large; leaf-stalk
not winged, 2-8 cm; blade below gray-green, above green,
kidney-shaped-pentagonal to triangular or lanceshaped, 6-10 x 5-14 cm,
basally 3-5-veined, base broadly heart-shaped or flat, margin shallowly
to deeply lobed, irregularly coarsely toothed, teeth mucronulate, tip
pointed, tapering, or with a tail-pointed. Upper leaves are smaller,
shortly stalked, triangular or narrowly triangular. Uppermost leaves
narrowly lanceshaped or linear, bracteal-leaflike, usually with many
spherical buds in upper leaf axils and on synflorescence branches.
Flower-heads are numerous, arranged in branch-end narrow or broad
panicles, spreading by flowering, drooping afterwards. Involucres are
cylindric, 7-8 mm; phyllaries 4 or 5, oblong, outside hairless, at tip
blunt or pointed. Florets are 4 or 5; flower yellow, 6-7 mm, with 2.5-3
mm tube and broadly tubular limb; lobes lanceshaped. Anthers protruding
out of flower. Seedpods are cylindric, 4-5 mm, hairless, ribbed, pappus
white, 5-6 mm. Ivy-Leaf Senecio is found in the Himalayas to China (SW
Sichuan, NW Yunnan) and N Myanmar, at altitudes of 2800-4100 m.
Flowering: August.
