FRASERA

Bruce G. Baldwin

Perennial herb (non-flowering rosettes preceding flower-stems, plants dying after flowering in Frasera albomarginata, Frasera parryi, Frasera puberulenta, Frasera speciosa, and Frasera umpquaensis; non-flowering rosettes appearing with flower-stems in others). Leaf: basal ± petioled; cauline opposite or whorled, < basal, base often fused-sheathing. Inflorescence: cyme or panicle of dense clusters. Flower: parts in 4s; calyx fused near base, lobes lanceolate; corolla rotate (bell-shaped), lobes >> tube, ridge between stamens fringed or scaled or 0, nectary pits prominent, 1(2) per lobe, margins of openings variously fringed; ovary sessile, style long and well differentiated or short and poorly differentiated, persistent, entire, stigmas 2.
± 15 species: temperate North America. (J. Fraser, Scottish collector of North America plants, 1750–1811) [von Hagen & Kadereit 2002 Syst Bot 27:548–572]
