Lobeleaf Groundsel

Packera multilobata (T. & G. ex A. Gray) W. A. Weber & Á. Löve

Comments

provided by eFloras
Packera multilobata is abundant and widespread west of the Continental Divide. Both morphology and habitat vary. In colder parts of its range, plants are shorter, caudices are better developed with clustered stems, and leaf lobes are larger. In desert-like habitats, basal leaves are narrower and more finely lobed, the tomentum is often persistent, and stems are usually single.

Biennials or perennials, 20–40+ cm; taprooted (caudices ascending to erect, weakly branched). Stems 1 or 2–5, loosely clustered, usually glabrous or glabrescent, sometimes sparsely tomentose throughout, axils (basal leaves) tomentose. Basal leaves (and proximal cauline) petiolate; blades obovate, oblanceolate, spatulate, or lyrate to sublyrate (± pinnately lobed, lateral lobes 3–6 pairs, smaller than terminal lobes), 40–80+ × 10–30+ mm, bases tapering, ultimate margins incised to dentate. Cauline leaves gradually reduced (sessile). Heads 10–30+ in open, corymbiform or subumbelliform arrays. Peduncles conspicuously bracteate, glabrous or tomentose. Calyculi conspicuous. Phyllaries 13–21, green (tips often yellow), 4–9+ mm, glabrous or sparsely tomentose (at least proximally). Ray florets 8–13; corolla laminae 7–10 mm. Disc florets 40–50+; corolla tubes 4–5 mm, limbs 3–4 mm. Cypselae 2–3 mm, glabrous or hirtellous on ribs; pappi 5–6 mm. 2n = 46, 92.

Packera multilobata

provided by wikipedia EN

Packera multilobata is a species of flowering plant in the aster family known by the common name lobeleaf groundsel. It is native to the western United States from California to Wyoming to New Mexico, where it is common and can be found in many habitat types.

It is an annual or perennial herb producing a single stem or a cluster of several stems up to about half a meter tall from a taproot and branching caudex unit. The leaves are divided into several lobes, often so deeply that they look like separate leaflets. The inflorescence is a wide array of flower heads lined with green or yellowish phyllaries and containing many yellow disc florets. Most heads have a fringe of yellow ray florets, but at times these can be absent.

Parts of this plant were used medicinally by Native American peoples including the Navajo and Yavapai.[1]
