Ursinia (John Ursinus, of Regensburg, 1608-1666; author of "Arboretum Biblicum"). Compositae. Here belongs the hardy annual known to the trade as Sphenogyne speciosa. Annuals, perennials, or subshrubs: lvs. alternate, serrate, pinnatifid or usually pinnatisect: rays the same color on both sides or purplish brown beneath; involucre hemispherical or broadly campanulate: achenes often 10-ribbed. — A genus of about 60 species, all native to S. Afr. One species, U. annua, is also found in Abyssinia. In Flora Capensis, vol. 3 (1864-65), Sphenogyne and Ursinia are treated as separate genera, the distinctions being as follows: the achene is cylindrical in Sphenogyne, but obovate or pear-shaped in Ursinia, distinctly tapering to the base: the pappus is uniseriate in the former, biseriate in the latter, the inner series consisting of 5 slender white bristles. In the course of time these distinctions have been dropped and Sphenogyne included in Ursinia. CH
