Higher Taxonomy
Family: MontiaceaeView DescriptionDichotomous Key

Habit: Annual to perennial herb; generally fleshy. Stem: 1--many, generally glabrous. Leaf: simple, alternate or opposite. Inflorescence: axillary or terminal; cyme, raceme, panicle, umbel, or flower 1. Flower: bisexual, radial; sepals generally 2(9), free; petals (1)2--19, free or +- fused; stamens 1--many, epipetalous or not, anthers pink, rose, or yellow; ovary superior, chamber 1, ovules 1--many, placenta basal or free-central; styles (0)1--8, generally fused at base, branched. Fruit: capsule, circumscissile or 2--3-valved. Seed: 1--many, shiny or +- pebbly or sculptured, black or gray, generally with oil-filled appendage as food for ants.
Genera In Family: +- 22 genera, +- 230 species: generally temperate America, Asia, Australia, Europe, Kerguelen Is, New Zealand, southern Africa, poorly represented in Europe; some cultivated (Lewisia, Calandrinia). Note: All CA genera previously included in Portulacaceae; details of flowers, seeds require 20× magnification.
Unabridged Note: May include Hectorellaceae.

Genus: CalandriniaView DescriptionDichotomous Key

Habit: Annual [perennial herb], +- fleshy, +- glabrous or glaucous. Stem: several to many, prostrate to ascending [erect], 3--45 cm. Leaf: simple, alternate; blade linear to spoon-shaped, flat [cylindric]. Inflorescence: raceme or panicle; bracts leaf-like [or scarious]. Flower: sepals 2, overlapped, persistent in fruit; petals (3)5(7), +- pink-purple (white); stamens 3--15; stigmas 3. Fruit: 3-valved. Seed: 6--many, ovate to +- elliptic, generally black, smooth, finely tubercled, or with fine, net-like pattern.
Species In Genus: 14 species: western America. Etymology: (J.L. Calandrini, Swiss scientist, 1703--1758) Note: Other taxa in TJM (1993) moved to Cistanthe; number of species (150) indicated in TJM (1993) and TJM2 (2012) should have been much smaller. Calandrinia menziesii added, as segregated from Calandrinia ciliata, which as newly circumscribed does not occur in CA and therefore has been removed.
