DRYMOCALLIS

Barbara Ertter


Perennial herb, 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: northern 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 southwestern Oregon, possibly northwestern California.
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.
