NATURALIZED Habit: Annual but often over-wintering, prostrate to erect, 7--50 cm; taproot slender. Stem: internode hairs in line. Leaf: +- evenly spaced; blade 8--45 mm, +- ovate; margin +- not papillate, +- flat, shiny, often ciliate near base. Inflorescence: terminal or axillary, few-flowered, +- dense; bracts leaf-like; pedicels spreading to erect, in fruit curved to reflexed. Flower: sepals 5, 3--4.5 mm, > 6 mm in fruit, lanceolate to ovate, acute to obtuse, glabrous or +- glandular-hairy, margin +- widely scarious, ribs often 1 or 3 near base; petals 5, 0.7--0.9 × sepals. Seed: 0.9--1.3 mm, dark red-brown to brown, tubercles rounded. Chromosomes: 2n=40,42,44. Ecology: Oak woodland, meadows, disturbed areas; Elevation: < 1500 m. Bioregional Distribution: NW, CaRH, n&c SNF, n SNH, GV, CCo, SnFrB, SCo, ChI, DSon; Distribution Outside California: North America; native to southwestern Europe. Flowering Time: Feb--Sep Note: Often a pernicious urban weed; sometimes difficult to distinguish from Stellaria neglecta, Stellaria pallida. Jepson eFlora Author: Ronald L.

MAP CONTROLS 1. You can change the display of the base map layer control box in the upper right-hand corner.
2. County and Jepson Region polygons can be turned off and on using the check boxes.
(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 occurrence).
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.
