Dudleya palmeri

Higher Taxonomy
Family: CrassulaceaeView DescriptionDichotomous Key

Habit: Annual to shrub [(+- tree-like or climbing)], fleshy. Leaf: generally simple, alternate or opposite, in dense to open, basal (or terminal) rosettes or basal and cauline, not in rosettes, reduced distally or not, margin often +- red. Inflorescence: generally cyme, generally bracted. Flower: generally bisexual; sepals generally 3--5, generally +- free; petals generally 3--5, +- free or fused; stamens >> to = sepals, epipetalous or not; pistils generally 3--5, simple, fused at base or not, ovary 1-chambered, placenta 1, parietal, ovules 1--many, style 1. Fruit: follicles, generally 3--5. Seed: 1--many, small.
Genera In Family: +- 33 genera, +- 1400 species: +- worldwide, especially dry temperate; many cultivated for ornamental. Note: Water-stressed plants often +- brown or +- red. Consistent terminology regarding leaves, bracts difficult; in taxa with rosettes (e.g., Aeonium, Dudleya, some Sedum), structures in rosettes are leaves, those on peduncles are bracts, and those subtending flowers are flower bracts; in taxa where inflorescence is terminal, rosette leaves may "become" bracts as stem rapidly elongates to form inflorescence. Seed numbers given per follicle.

Genus: DudleyaView DescriptionDichotomous Key

Habit: Perennial herb, fleshy, glabrous, bisexual. Stem: generally caudex- or corm-like, branched or not, +- covered with dried leaves. Leaf: in rosettes, evergreen or +- deciduous in summer (withering, falling or not), waxy or not, base wounding purple-red (yellow) or generally not. Inflorescence: cyme; flower bracts +- subtending pedicels, < bracts; bracts alternate. Flower: sepals 5, fused below; petals 5, fused at base, erect to spreading above; stamens 10, epipetalous; carpels 5, +- fused below. Fruit: follicles 5, erect to spreading, many-seeded. Seed: < 1 mm, narrowly ovoid, brown, striate.
Species In Genus: +- 46 species: southwestern North America; some used as groundcover or cultivated for ornamental. Etymology: (W.R. Dudley, 1st head of Botany Department, Stanford University, 1849--1911) Note: Fruit just before opening generally most reliable for orientation; insect damage may cause branching in taxa characterized as non-branching.
Unabridged Note: Whether or not leaves of Dudleya cymosa subsp. costatifolia, Dudleya saxosa subsp. saxosa, Dudleya variegata wound purple-red, red, yellow, or some other color at base when removed is evidently unknown.

Dudleya palmeri (S. Watson) Britton & Rose
Habit: Rosettes 1--8, 5--55 cm wide. Stem: < 2 dm, (2)4--10 cm wide, of older plants covered by dry leaves. Leaf: evergreen, 15--25, 5--20 cm, 1.5--5 cm wide, 3--8 mm thick, lance-oblong to generally lanceolate, adaxially flat or convex (transversely), glaucous or not, base wounding purple-red, tip acute to acuminate, margins often angled between ad-, abaxial surfaces. Inflorescence: peduncle 15--85 cm, 4--11 mm wide; 1° branches +- 3, branched 0--2 ×; terminal branches 5--8 cm, 5--14-flowered; pedicels 2--10 mm. Flower: sepals 3--5 mm, deltate-ovate, acute; petals 11--16 mm, 3--5 mm wide, fused 1.5--2 mm, elliptic, red over yellow but appearing orange-pink, tips erect, acute. Chromosomes: 2n=136,170,238.
Ecology: Coastal rocky areas, inland marine sands; Elevation: generally < 200 m. Bioregional Distribution: c&s CCo, SnFrB, SCo. Flowering Time: May--Jul Note: Only +- distinct from Dudleya lanceolata. May intergrade with Dudleya caespitosa, Dudleya cymosa.
