KECKIELLA BUSH PENSTEMON

Margriet Wetherwax & Noel H. Holmgren


Subshrub or shrub. Stem: wand-like to much-branched. Leaf: drought-deciduous, ± opposite or in 3s, distal occasionally alternate; sessile to short-petioled. Inflorescence: panicle or spike-like; bracts reduced. Flower: calyx lobes 5, ± equal; corolla ± white, ± yellow, or red, short-glandular outside, upper lip ± hooded, 2-lobed, lobes rounded, external in bud, lower lip rounded, lobes often reflexed; stamens 4, filaments attached at 1 level, densely nonglandular-hairy at base, anthers small, glabrous, anther sacs generally spreading flat at dehiscence; staminode well developed, glabrous to densely bearded; nectary a disk; stigma unlobed. Fruit: septicidal and sometimes also loculicidal at tip, ovoid. Seed: many, irregularly angled.
7 species: especially California, western Nevada, western Arizona, Baja California. (David D. Keck, California botanist, 1903–1995; Keckia used earlier, for genus of fossil algae) [Freeman et al. 2003 Syst Bot 28:782–790] Red-flowered species are hummingbird-pollinated.
