Crassula ovata
JADE PLANT


Higher Taxonomy
Family: CrassulaceaeView DescriptionDichotomous Key
Common Name: STONECROP FAMILY
Habit: Annual to shrub [+- tree-like or climbing], fleshy. Leaf: generally simple, alternate or opposite (whorled), in dense to open, basal (or terminal) rosettes, or basal and cauline (not in rosettes), reduced on distal stem or not, often +- red. Inflorescence: generally a cyme, panicle-like, 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(--8), simple, fused at base or not, ovary 1-chambered, placenta 1, parietal, ovules 1--many, style 1 per pistil. Fruit: follicles, generally 3--5. Seed: 1--many, small.
Genera In Family: +- 33 genera, +- 1400 species: +- worldwide, especially dry temperate; many cultivated for ornament. Note: Water-stressed plants often +- red. Consistent terminology regarding leaves, bracts difficult; in Aeonium and Dudleya, structures in rosettes are leaves, those on peduncles are bracts, and those subtending flowers are flower bracts; thus in taxa where the inflorescence is terminal, rosette leaves may "become" bracts as stem rapidly elongates to form an inflorescence. In Sedum structures below the inflorescence are interpreted as stems and leaves, not peduncles and bracts. Seed numbers given per follicle. SCIED: Scientific Editor: Bruce G. Baldwin, Thomas J.

Genus: CrassulaView DescriptionDichotomous Key


Habit: Annual, perennial herb, shrub, glabrous (hairy). Stem: erect to decumbent, branched or not. Leaf: opposite, 0.1--7 cm, linear to deltate or obovate, bases fused, +- sheathing; margins generally entire. Inflorescence: terminal panicle or flowers 1 in axils of leaves, either 2 per node, axillary, or 1 per node, terminal but appearing axillary by overtopping of main axis. Flower: erect, sepals 3--5, +- fused at base; petals 3--5, spreading or recurved, free or +- fused at base; stamens = sepals in number; pistils 3--5. Fruit: spreading to erect. Seed: 0.2--0.6 mm, elliptic to elliptic-oblong (spheric, reniform), generally with longitudinal lines, sometimes +- smooth or papillate, red-brown. Chromosomes: x=(7)8.
Etymology: (Latin: diminutive of thick) Note: Crassula argentea Thunb., a synonym of Crassula ovata (Mill.) Druce, a waif.

Crassula ovata (Mill.) Druce
WAIF
Habit: Shrub, rounded. Stem: many, erect, 30--50 cm, to 20 cm diam, young bark +- smooth, silvery. Leaf: cauline, generally > 4 pairs, subsessile, 20--70 mm, obovate, bright green, tip rounded, margins entire. Inflorescence: panicle, compact; pedicels 8--12 mm. Flower: parts generally in 5s; sepals erect, 1--2 mm, wide-deltate, acute; petals (5)7--10 mm, spreading, lanceolate to lance-oblong, acute, white, tinged pink. Fruit: erect, ovoid. Seed: 30--50, oblong, with rows of pointed papillae at 20×.
Ecology: Persisting from cultivation and at dump sites, wildland-urban interface, generally along coast; Elevation: < 100 m. Bioregional Distribution: SCo; Distribution Outside California: native to southern Africa. Flowering Time: Dec--Feb
Synonyms: Crassula argentea Thunb.; Toelkenia ovata (Mill.) P.V. Heath

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.
