Common Name: MINER'S LETTUCE FAMILY 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. eFlora Treatment Author: John M.

Common Name: MINER'S LETTUCE Habit: Annual. Stem: 1--40 cm, spreading to erect. Leaf: basal 1--25 cm, blade < 4 cm, < 3 × longer than wide, elliptic to reniform, tip rounded to acute, petiole linear; cauline fused into < 10 cm diam, round, +- obtuse-angled, or +- square disk (or free on 1 side). Inflorescence: stalked or not, open or dense, 1-bracted at base; flowers 5--40. Flower: sepals 1.5--5 mm; petals 2--6 mm, white or +- pink. Fruit: 1.5--4 mm. Seed: 1.2--2.7 mm, ovate to round, shiny, smooth. Note: Highly variable; subspecies difficult because of environmental modification of character states, genetic mixing among polyploids, and geographic overlap of distinct, self-pollinated forms.
Claytonia perfoliata Willd. subsp. perfoliata

MAP CONTROLS 1. You can change the display of the base map and layers by clicking on the layer control box in the upper right-hand corner.
2. California county polygons can be turned off and on in the layer control box.
3. Filling of Jepson subdivision polygons can be turned off and on in the layer control box.
4. Moving the cursor over any numbered cluster will show the range boundary of the included specimens (with a blue polygon).
5. Marker clustering can be turned off by clicking this link:
Marker Clustering OFF WARNING: Turning this off might cause maps with large numbers of specimens to load slowly.
(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurence).

MAP LEGEND View all CCH records 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.
