Doronicum (Latinized Arabic name). Compositae. "Leopard's Bane"
Hardy herbaceous plants, 1-2 ft. high, with yellow flowers, mostly one on a stem and 2-3 in. across, borne high above the basal crown of foliage, from April to June. From 10-24 species, natives of Europe and temperate Asia. Stems little branched or not at all. Leaves: alternate, radical ones long-stalked, stem leaves distant, often clasping the stem. The genus is allied to Arnica, and distinguished by the alternate leaves and by the style. The plants are of easy culture in rich loam. The flowers are numerous and good for cutting. Doronicums have been strongly recommended for forcing.
A. Root-leaves, not notched at the base, ovate.
plantagineum: Glabrous, but woolly at the neck, with long, silky hairs. Root-leaves: ovate or oval, wavy toothed. Stem-leaves: nearly entire, the lower ones narrowed into a petiole and not cured, the upper ones sessile, oblong, acuminate. Sandy woods of Europe. Rhizome tuberous, roundish, or creeping obliquely. Stalk of the root-leaves about 3 in. long. Typically about 2 ft. high.
excelsum: Is more robust, grows about 5 ft. high and is probably more cultivated than any other kind of Doronicum. Flowers: sometimes 4 in. across.
Clusii, Tausch: Leaves: ovate or oblong; stem-leaves half-clasping, with distant teeth or many small ones. One subvariety has long, silky hairs on its leaves, while another has none. Swiss and Austrian Alps. "Soft-, downy foliage," J. W. Manning. “Grows 2 ft. high," Woolson. "Larger and later flowers. than D. Caucasicum," Ellwanger and Barry.
AA. Root-lvs. notched at the base, heart-shaped.
B. Root tuberous.
Pardalianches: Hairy, leaves toothed; lower stem leaves cared at the base of the stalk, sub-ovate, upper ones spatulate-cordate, highest ones cordate-clasping, acute. Woods of lower mountains of Europe. While all species are typically 1-flowered, many of them may have now and then more than 1 flower on a stem, and this species particularly may have 1-5 flowers.
BB. Root not tuberous.
Caucasicum: Glabrous except as noted above: leaves crenate-dentate, lower stem-leaves eared at the base of the stalk, the blade subcordate, highest ones cordato to half-clasping. Shady woods of Caucasus, Sicily, etc. Flowers 2 in. across.
Austriaoum: Hairy: leaves minutely toothed, lower stem-leaves. spatulate-ovate, abruptly narrowed at the base, half-clasping, highest ones cordate~clasping, lanceolate. Sub-alpine woods, Europe.
