1. Flowers opening narrowly, petals ± 

erect 

Upright; vertically oriented.

; styles 1.5–3 mm, ± slender

2. Petiole generally densely hairy with nonglandular hairs; terminal 

leaflet 

A leaf-like unit of a compound leaf; distinguished from a leaf by the absence in its axil of a bud, branch, thorn, or flower; lacking lateral, basal appendages (stipules); either simple (leaf 1-compound, with primary leaflets) or compound (leaf 2-compound, with primary and secondary leaflets; 3-compound, with primary, secondary, and tertiary leaflets, etc).

generally > 10-toothed, tip 

obtuse 

Having a short-tapered, blunt tip or base, the sides convex or straight and converging at more than a right angle.

to rounded; n California ..... D. rhomboidea

2' Petiole sparsely hairy with glandular and nonglandular hairs; terminal leaflet < 10-toothed, tip ± 

truncate 

Abruptly (not gradually) narrower or smaller at base or tip, as if cut straight across or nearly so.

; TR ..... D. cuneifolia

3. Stem 20–45 cm; leaves 5–15 cm; SnBr ..... var. cuneifolia

3' Stem generally 5–20 cm; leaves 2–10 cm; SnGb ..... var. ewanii

1' Flowers opening widely, petals 

spreading 

Oriented more or less perpendicularly to the axis of attachment; often, more or less horizontal.

; styles generally < 1.5 mm, swollen

pedicel 

Stalk of an individual flower in an inflorescence, or the corresponding structure in fruit.

hairs generally glandular ..... D. glandulosa

5. Petals ± elliptic-ovate, 3.5–6 mm wide, cream to pale yellow; inflorescence appearing ± leafy (bracts ± 1/2 subtended branches); 

pedicels 

Stalk of an individual flower in an inflorescence, or the corresponding structure in fruit.

1–5 mm

6. Petals generally 3.5–5 mm, generally pale yellow, sometimes cream; inland ..... var. glandulosa

6' Petals generally 4.5–6.5 mm, cream (± yellow); coastal ..... var. wrangelliana

5' Petals narrow-elliptic-obovate, 2–3.5 mm wide, yellow; inflorescence not appearing leafy (bracts < 1/2 subtended branches); pedicels 2–10 mm

7. Inflorescence branches spreading (angle generally 25–55°); leaflet teeth mostly double; sepal tip generally obtuse ..... var. reflexa

7' Inflorescence branches 

ascending 

Curving or angling upward from base, or about 30-60 degrees less than vertical or away from axis of attachment.

(angle generally 10–30°); leaflet teeth mostly single; sepal tip 

acute 

Having a short-tapered, sharp tip, the sides convex or straight and converging at less than a right angle.

..... var. viscida

4' Petals > sepals, ± obovate to round; stem and pedicel hairs glandular or not – > 900 m

8. Stem generally 5–25 cm; sheathing 

leaf 

Organ arising from a stem, generally composed of a stalk (petiole) and a flat, expanded, green, photosynthetic area (blade); distinguished from a leaflet by the presence in its axil of a bud, branch, thorn, or flower; sometimes with lateral, basal appendages (stipules); either simple (toothed, lobed, or dissected but not divided into leaflets) or compound (divided into leaflets).

base generally appressed-hairy – generally glandular above; rocky areas, 2300–3900 m ..... D. pseudorupestris

9. Leaflets generally 4 per side; calyx with prominent nonglandular hairs 1–1.5 mm; styles generally ± red ..... var. crumiana
