Penstemon grinnellii var. grinnellii


Higher Taxonomy
Family: PlantaginaceaeView DescriptionDichotomous Key
Common Name: PLANTAIN FAMILY
Habit: Annual to shrub, some aquatic. Leaf: basal or cauline, alternate or opposite (whorled), simple, entire to dentate or lobed, venation generally pinnate; stipules 0. Inflorescence: raceme, spike, or flowers axillary in 1--few-flowered clusters; flowers few to many, each subtended by 1 bract. Flower: unisexual or bisexual, radial or bilateral; sepals 4--5, generally fused at base; corolla 4--5-lobed, scarious or not, persistent or not, generally 2-lipped, upper lip generally 2-lobed, lower generally 3-lobed, spur present or not, tube sac-like at base or not; stamens 2 or 4, alternate corolla lobes, epipetalous, staminode 0 or 1--2, anthers opening by 2 slits; ovary superior, [1]2--4-chambered, style 1, stigma lobes 0 or 2. Fruit: generally a capsule, septicidal, loculicidal, circumscissile, or dehiscing by terminal slits or pores.
Genera In Family: +- 110 genera, +- 2000 species: worldwide, especially temperate. Note: Veronicaceae sensu Olmstead et al. Recently treated to include Callitrichaceae, Hippuridaceae, and most non-parasitic California genera of Scrophulariaceae (except Buddleja, Diplacus, Erythranthe, Limosella, Lindernia, Mimetanthe, Mimulus, Myoporum, Scrophularia, Verbascum). California Maurandya moved to Holmgrenanthe and Maurandella. Mohavea moved to Antirrhinum. Limnophila ×ludoviciana Thieret an occasional agricultural weed in rice fields. Hebe ×franciscana (Eastw.) Souster, Hebe speciosa (R. Cunn.) Andersen only cultivated.

Genus: PenstemonView DescriptionDichotomous Key

Common Name: BEARDTONGUE
Habit: Perennial herb to shrub. Leaf: generally opposite, entire to toothed; distal sessile. Inflorescence: panicle, raceme, cyme, or flowers in whorls; bracts generally small. Flower: calyx lobes 5, +- equal; corolla tube +- cylindric or lower side expanded, +- 2-lipped, generally pink or blue to purple (some red, yellow, or white), upper lip 2-lobed, external in bud; stamens 4, filament bases glabrous, attached to corolla at different levels, anther sacs 2, valves generally spreading +- flat at dehiscence; staminode attached near base of corolla tube, well developed, generally hairy adaxially; nectaries 2, at bases of upper stamens; stigma unlobed. Fruit: septicidal and sometimes also loculicidal at tip. Seed: generally many, irregularly angled.
Etymology: (Latin & Greek: almost thread, from stamen-like staminode) Note: Largest genus of flower plants endemic to North America. Penstemon subglaber, Penstemon strictus may persist in SNH, from commercial wildflower seed mixes or plantings; both native to Rocky Mountains.

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.
