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 ornament, 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. eFlora Treatment Author: Daniel Potter & Barbara Ertter, family description, key to genera, treatment of genera by Daniel Potter, except as noted Scientific Editor: Daniel Potter, Thomas J. Rosatti.
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. 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. eFlora Treatment Author: Barbara Ertter Reference: Ertter 2007 J Bot Res Inst Texas 1:31--46
Drymocallis hansenii (Greene) Rydb.
NATIVE Stem: generally 1, 30--90 cm, glandular hairs abundant at base. Leaf: basal generally 10--25 cm, sheathing base generally glabrous, lateral leaflet pairs 3--4, terminal leaflet generally 20--50 mm, widely obovate, rounded, teeth single to double, 6--11 per side. Inflorescence: not leafy, narrow, branch angle generally 10--30°; pedicels generally 1--10 mm, lowermost to 20 mm, glandular hairs and short nonglandular hairs abundant. Flower: opening widely; hypanthium bractlets 2--4 mm, 0.5--1 mm wide, linear to narrow-elliptic; sepals 4--8 mm, acute; petals spreading, 4--7 mm, >= sepals, widely obovate, cream; styles +- 1 mm. Fruit: < 1 mm, light brown. Ecology: Moist meadows; Elevation: 1200--2200 m. Bioregional Distribution: CaR, SN. Flowering Time: Jun--Sep Note: Coarser plants from Wrn probably undescribed taxon. Intergrades with Drymocallis lactea at higher elevation. Synonyms: Potentilla glandulosa subsp. hansenii (Greene) D.D. Keck Unabridged Note: Similar to Drymocallis convallaria (Rydb.) Rydb. (Alaska to Oregon, Montana, Utah) with tall, generally single stem 2--4 mm diam; comparable but coarser plants from Wrn probably undescribed. Intergrades with Drymocallis lactea at higher elevation.

MAP LEGEND View all CCH records 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.
