Moenchia erecta (L.) G. Gaertn., B. Mey. & Scherb.COMMON NAME: UPRIGHT CHICKWEED subsp. erecta
Habit: Plant glabrous, glaucous. Stem: 2.5--15 cm. Leaf: basal +- petioled, 5--18 mm, +- oblanceolate; cauline sessile, 3--12 mm, linear to lance-linear, ascending, rigid. Flower: sepal veins 3, lateral faint; petals lanceolate, white. Chromosomes: 2n=38.

Unabridged Note: According to Doreen Smith, observed at Sea Ranch, Sonoma Co., which, if verified, would expand range to include southern NCo. 1 other variety, native to western Mediterranean, introduced in southern Africa, Australia.
