Rhaponticum (old Greek name for rhubarb, the same as occurs in Rheum
Rhaponticum). Compositae. Under this generic name at least one species
is still catalogued, although the genus is now included as a section of
Centaurea. Nine species are recognized in the group, extending from
Morocco and Algiers to China. They are more or less thistle-like stout
herbs, mostly or entirely perennial, with large solitary yellow, pink
or purplish heads, the lvs. usually white-tomentose beneath: florets
all equal and perfect: fr. 4-angled; pappus rough or feathery- Two
species may be described here, under the genus Centaurea. C.
Rhaponticum, Linn. (Rhaponticum scariosum, Lam.). Perennial, 2-2 1/2
ft., with purplish fl.-heads: lvs. tomen- tose beneath, glabrous above,
the lower ones ovate or cordate and finely toothed, petiolate, the
upper ones sessile and oblong: outer scales of involucre scarious
(dry). Alps, Switzerland. B.M. 1752. Appears not to be offered. C.
cynarodes, Link (R. cynaroides, Less.). Perennial, from the Pyrenees
region: heads few and erect, purplish-fld. : lvs. large, oblong to
ovate, attenuate at base, acuminate, the lower ones pinnately parted,
the upper scarcely pinnatifid, all the lobes acutely toothed, more or
less tomentose beneath: scales of involucre ciliate-serrate.—Listed
abroad for outdoor planting. L. H. B.
