Genus: FraseraView DescriptionDichotomous Key

Habit: 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.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
