Key to families | Table of families and genera This text currently parallels The Jepson Manual: Vascular Plants of California, Second Edition that is now available at the University of California Press. Text appearing in blue on this page will not appear in the printed book; it will be displayed only on the Web. Specimen numbers are hyperlinked to records in the Consortium of California Herbaria data view where possible. Taxa are hyperlinked to entries in the Jepson Interchange via the "[Online Interchange]" link. |
Perennial, hairs short, simple, nonglandular and/or long, cross-walled, glandular.
Stem: ± erect, from ± branched caudex or rhizomes.
Leaf: basal and cauline, alternate, odd-1-pinnately compound; leaflets toothed, terminal generally >= lateral.
Inflorescence: cyme, ± open; pedicels straight, bractlets 0.
Flower: hypanthium ± shallow, bractlets 5; sepals ± triangular; petals < to > sepals, white to yellow; stamens generally 20–25, pollen sac 1, horseshoe-shaped; pistils many, styles fusiform, attached below fruit middle.
Fruit: achene, glabrous.
n=7.
30 species: n temperate. (Greek: wood beauty) [Ertter 2007 J Bot Res Inst Texas 1:31–46] Recognition based on morphological, molecular evidence. Drymocallis ashlandica (Green) Rydb. (inflorescence narrow, petioles glandular, petals yellow) in sw OR, possibly nw CA.
Unabridged note: Convergence of morphological, molecular evidence mandates recognition of Drymocallis; infrageneric taxonomy provisional. Key characters include relative proportions of 2 hair types: short simple nonglandular hairs and longer cross-walled glandular hairs.
