This text currently parallels The Jepson Manual: Vascular Plants of California, Second Edition that is now available at the University of California Press.
Text appearing in blue on this page will not appear in the printed book; it will be displayed only on the Web. Specimen numbers are hyperlinked to records in the Consortium of California Herbaria data view where possible. Taxa are hyperlinked to entries in the Jepson Interchange via the "[Online Interchange]" link.
Annual 10–60 cm, green, branches few to many; roots ± yellow.
Leaf: alternate, sessile, 5–35 mm, entire, lanceolate to oblong.
Inflorescence: spike, loose to dense, subtended by outer, leaf-like bracts; inner bract 1 per flower, ± leaf-like, entire or pinnately lobed.
Flower: calyx = or slightly < corolla, sheath-like, generally cut completely to base abaxially, partially surrounding corolla tube laterally, notched ± 1 mm at tip; corolla 2-lipped, club-shaped, tubular below, expanded laterally, upper lip folded lengthwise, tip rounded, closed, opening directed downward forming a hood enclosing anthers and style; lower lip <= upper lip, obscurely 3-lobed; fertile stamens 4 and staminodes 0, or 2 with adaxial pair of staminodes (attached deeper in corolla tube), anther sacs generally 2 per stamen, ± overlapping, tufted-hairy at base, unequal in size and placement; ovary 2-chambered, glabrous, ovules many, style bent near tip, stigma barely exserted.
Seed: attached at side; seed coat tight-fitting, netted.
4 species: saline and alkaline habitats, w North America. (Greek: salt plant) [Tank et al. 2009 Syst Bot 34:182–197] Formerly included in Cordylanthus. Close to Dicranostegia, together forming the Pseudocordylanthus clade (see Tank et al. 2009); distinguished by salt-tolerant ecology, inflorescence, calyx, stamens; flowers May–Nov.
