Lavatera olbia
TREE LAVATERA


Higher Taxonomy
Family: MalvaceaeView DescriptionDichotomous Key
Common Name: MALLOW FAMILY
Habit: Annual to tree; generally with stellate hairs, often with bristles or peltate scales; juice generally mucilage-like; bark fibrous. Leaf: generally cauline, alternate, petioled, simple [palmate-compound], generally palmate-lobed and/or veined, generally toothed, evergreen or not; stipules persistent or not. Inflorescence: head, spike, raceme, or panicle, in panicle or not (a compound panicle), or flowers >= 1 in leaf axils, or flowers generally 1 opposite a leaf or on a spur; bracts leaf-like or not; bractlets 0 or on flowering stalks, often closely subtending calyx, generally in involucel. Flower: generally bisexual, radial; sepals 5, generally fused at base, abutting in bud, larger in fruit or not, nectaries as tufts of glandular hairs at base; petals (0)5, free from each other but generally fused at base to, falling with filament tube, clawed or not; stamens 5--many, filaments fused for most of length into tube around style, staminodes 5, alternate stamens, or generally 0; pistil 1, ovary superior, stalked or generally not, chambers generally >= 5, styles or style branches, stigmas generally 1 or 1--2 × chamber number. Fruit: loculicidal capsule, [berry], or 5--many, disk- or wedge-shaped segments (= mericarps).
Genera In Family: 266 genera, 4025 species: worldwide, especially warm regions; some cultivated (e.g., Abelmoschus okra; Alcea hollyhock; Gossypium cotton; Hibiscus hibiscus). Note: Recently treated to include Bombacaceae, Sterculiaceae, Tiliaceae. Mature fruit needed for identification; "outer edges" are surfaces between sides and back (abaxial surface) of segment. "Flower stalk" used instead of "pedicel," "peduncle," especially where both needed (i.e., when flowers both 1 in leaf axils and otherwise).

Genus: LavateraView DescriptionDichotomous Key


Habit: Annual, biennial, perennial herb, shrub, +- glabrous to stellate-hairy. Stem: erect, herbaceous to soft-woody. Leaf: petioled; blade ovate to lanceolate, shallowly to deeply 5--7(9)-lobed or lobes 0, generally crenate to dentate. Inflorescence: raceme-like or generally flowers 1[several] in leaf axils; bractlets 3, fused generally 1/2. Flower: generally showy; petals pink, purple, rose-purple or white, dark-veined or not; anthers near top of filament tube, below, generally not clustered; stigmas linear, on inner side of style branches. Fruit: +- disk-like; segments (6)10--19, indehiscent, smooth or variously ribbed and/or hairy, outer edges generally rounded, beak 0. Seed: 1 per segment, generally not firmly enclosed by, readily separating from fruit wall, reniform, glabrous.
Etymology: (Lavater brothers, 17th century Swiss physicians, naturalists) Note: Most species transferred to Malva, primarily on molecular data (Ray 1995, 1998); other commonly cultivated species that may escape including Lavatera cashmiriana Camb., Lavatera thuringiaca L.

Lavatera olbia L.
NATURALIZED
Habit: Generally bristly. Stem: erect, generally woody at base, generally 1--2 m, tomentose in youth, hairy to +- glabrous in age. Leaf: densely stellate-tomentose; petioles to 10 cm; blade generally to 15 cm, lower 3--5-lobed, acute to obtuse, upper oblong-ovate to lanceolate, often +- 3-lobed. Inflorescence: raceme-like or flowers 1 in leaf axils; flowering stalks 2--7 mm; bractlets widely ovate. Flower: petals 2--3 cm. Fruit: segments 17--19, puberulent or glabrous. Chromosomes: 2n=42.
Ecology: Disturbed places; Elevation: < 400 m. Bioregional Distribution: SCo (Laguna Canyon, Orange Co.); Distribution Outside California: native southwestern Europe, Mediterranean; widely cultivated. Flowering Time: May--Jun Note: Rarely escapes cultivation.

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.
