Sedella pentandra

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: SedellaView DescriptionDichotomous Key

Habit: Annual, erect, glabrous, branches 0 or near base. Leaf: early-deciduous, sessile, 0.4--0.7 cm, oblong-elliptic to ovoid (obovoid), basal opposite, free, not fused around stem, cauline alternate, entire, tip rounded to obtuse. Inflorescence: terminal, flowers 1--2+ in 0--3-branched cyme, subsessile. Flower: sepals 5; petals 5, +- fused at base, linear to narrow-ovate, pale to bright or green-yellow, midrib often +- red; stamens 5 or 10, anthers 0.2--0.4 mm, yellow or red-brown; pistils 5, oblong, bases rounded, styles 0.2--1.2 mm, erect or recurved, stigmas +- 0.1 mm diam. Fruit: +- indehiscent, utricle-like, erect to outcurved, glabrous or glandular. Seed: 1, 0.7--2 mm, club-like, brown.
Species In Genus: 3 species: California. Etymology: (Latin: diminutive of Sedum) Note: Parvisedum is a superfluous name for Sedella.

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.
