Dudleya virens subsp. virens

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.

Species: Dudleya virensView Description 

Habit: Rosettes many, 4--25 cm wide. Stem: 1--8 cm wide. Leaf: evergreen, 3--25 cm, 15--30 mm wide, oblong, 4--6 mm thick, in ×-section +- elliptic or in upper 1/2 round, glaucous or not, +- fragrant or not. Inflorescence: peduncle 6--70 cm, 1.5--15 mm wide; 1° branches 2--many, branched 0--3 ×; terminal branches 1--10 cm, 3--20-flowered; pedicels 1--5 mm. Flower: sepals 2--4 mm, acute; petals 7--10 mm, 2--3 mm wide, fused 1--2 mm, elliptic, acute, white to pale yellow, some with red, keels rose or orange-brown.
Note: 1 other subsp., Guadalupe Island, Mexico.
Unabridged Note: 1 other subsp., Dudleya virens subsp. extima Moran, Guadalupe Island, Mexico.

Dudleya virens (Rose) Moran subsp. virens
Habit: Rosettes 5--10(18) cm wide. Stem: 1--3.2 cm wide. Leaf: 20--50, outer lax to erect, 3--10 cm, 7--16 mm wide, 2--4 mm thick, elliptic to +- round in ×-section in upper 1/2, triangular-lanceolate to lance-linear, green, rarely glaucous, base 8--15 mm wide, tip acute. Inflorescence: peduncle 7--46 cm, 4--7 mm wide, easily broken when dry; 1° branches often several, branched 0--3 ×; terminal branches 3--5 cm long, 5--12-flowered; pedicels 2--4 mm. Flower: petals 8--10 mm, spreading from middle, white, keels rarely with red to orange-brown. Chromosomes: 2n=34.
Ecology: Rocks, cliffs, coastal flats; Elevation: < 500 m. Bioregional Distribution: s ChI (San Clemente Island). Flowering Time: Apr--Jun Note: May comprise 2 entities; study needed.
Unabridged Note: May comprise 2 entities, 1 more similar to Dudleya virens subsp. insularis or Dudleya virens subsp. hassei; study needed. Does not include Dudleya matsonii P.H. Thomson, apparently a garden hybrid not involving Dudleya virens.
