Lauramay T. Dempster (except as specified)

Annual, perennial herb, sometimes strongly scented; odor generally disagreeable
Leaves simple, pinnately lobed, or compound; petioles sometimes sheathing; basal ± whorled; cauline opposite, petioled to sessile
Inflorescence: cyme, panicle, or head-like, generally ± dense
Flowers generally bisexual; calyx fused to ovary top, limb 0 or highly modified (if present, lobes generally 5–15, coiled inward, becoming plumose, pappus-like, spreading in fruit); corolla radial to 2-lipped, lobes generally 5, throat generally > lobes, > tube, base generally spurred or swollen, tube slender, long or short; stamens generally 1–3, epipetalous; ovary inferior, chamber generally 1 (sometimes 3 but 2 empty or vestigial)
Fruit: achene, smooth, ribbed, or winged
Genera in family: ± 17 genera, 300 species: generally temp, worldwide except Australia. Some species cultivated (Centranthus ), some medicinal (Valeriana )
Reference: [Ferguson 1965 J Arnold Arbor 46:218–225]



Stem erect, equally and repeatedly forked
Leaves cauline, generally simple, entire or toothed
Inflorescence: cymes, dense, terminal, generally paired, subtended by involucre-like ring of bracts, peduncled

V. locusta (L.) Betcke

Stem 1–4 dm, sparsely hairy; hairs pointed down
Leaves 0.5–3 cm; lower petioled; upper ± sessile; blade obovate to narrowly oblong, entire, upper sometimes dentate
Flower: corolla 1.5–2 mm, white, lobes bluish
Fruit 2–3 mm; fertile chamber flanked by thickened, corky wall on 1 side, by empty chambers on opposite side; groove between sterile chambers narrow, shallow
Chromosomes: 2n=16
Ecology: Moist, generally shaded sites
Elevation: < 1400 m.
Bioregional distribution: Klamath Ranges, Outer North Coast Ranges, n Sierra Nevada, n Sacramento Valley, San Francisco Bay Area
Distribution outside California: to Washington, Idaho; native to Europe
Synonyms: V. olitoria (L.) Pollich
Plants from n SNF (Amador Co.) without thickened corky wall and with deep, wide groove between sterile chambers are V. carinata Loisel., native to Eur. Both species cultivated for edible leaves.

YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).
