Dudleya pulverulenta

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 pulverulenta (Nutt.) Britton & Rose
Habit: Covered with dense, mealy powder or chalky wax; rosette 1, 7--60 cm wide, white. Stem: 4--9 cm wide. Leaf: evergreen, 40--60, 8--25(27) cm, 3--10 cm wide, 3--10 mm thick, oblong, base 3--8 cm wide, tip acuminate to mucronate [to acute]. Inflorescence: peduncle 30--100(150) cm, 5--20 mm wide; 1° branches 2--6, branched 0--1 ×; terminal branches twisted at base, nodding in youth, spreading in age; pedicels 5--30(35) mm, reflexed in bud, in fruit often sharply bent, erect, becoming red. Flower: pendent; sepals waxy; petals 11--19 mm, fused 6--10 mm, red, with some wax. Chromosomes: 2n=34.
Ecology: +- common. Rocky cliffs, canyons; Elevation: generally < 1000 m. Bioregional Distribution: c&s CCo, s SCoRO, SCo, TR, PR; Distribution Outside California: northern Baja California. Flowering Time: May--Jul Note: Hybridizes with Dudleya lanceolata.
Synonyms: Dudleya pulverulenta subsp. pulverulenta
Unabridged Note: In Baja California may grade into Dudleya anthonyi Rose, which may best be treated as a subsp. of Dudleya pulverulenta.

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.
