Drymocallis pseudorupestris var. crumiana
CRUM'S WOODBEAUTY

Higher Taxonomy
Family: RosaceaeView DescriptionDichotomous Key

Common Name: ROSE FAMILY
Habit: Annual to tree, glandular or not. Leaf: simple to palmately or pinnately compound, generally alternate; stipules free to fused (0), persistent to deciduous. Inflorescence: cyme, raceme, panicle, cluster, or flowers 1; bractlets on pedicel ("pedicel bractlets") generally 0--3(many), subtended by bract or generally not. Flower: generally bisexual, radial; hypanthium free or fused to ovary, saucer- to funnel-shaped, subtending bractlets ("hypanthium bractlets") 0--5, alternate sepals; sepals generally 5; petals generally 5, free; stamens (0,1)5--many, anther pollen sacs generally 2; pistils (0)1--many, simple or compound, ovary superior to inferior, styles 1--5. Fruit: 1--many per flower, achene (fleshy-coated or not), follicle, drupe, or pome with generally papery core, occasionally drupe-like with 1--5 stones. Seed: generally 1--5 (per fruit, not per flower).
Genera In Family: 110 genera, +- 3000 species: worldwide, especially temperate; many cultivated for ornamental, fruit, especially Cotoneaster, Fragaria, Malus, Prunus, Pyracantha, Rosa, Rubus. Note: Number of teeth is per leaf or leaflet, not per side of leaf or leaflet, except in Drymocallis.

Genus: DrymocallisView DescriptionDichotomous Key

Habit: 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. Chromosomes: n=7.
Species In Genus: 30 species: northern temperate. Etymology: (Greek: wood beauty) Note: 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.
