Erythranthe latidens |
|
---|---|
broad-tooth monkeyflower |
|
Habit | Annuals, fibrous-rooted or filiform-taprooted. |
Stems | ascending to ascending-erect, geniculate at nodes, usually many-branched from base, 3–10(–25) cm, short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, gland-tipped. |
Leaves | basal and cauline, largest at base or near mid stem, sometimes unreduced in size up to distalmost nodes; petiole 0 mm; cauline blade palmately 3(–5)-veined, ovate to ovate-lanceolate, 8–26(–35) mm, base abruptly cuneate to rounded, sometimes subauriculate, margins entire or barely mucronulate to shallowly dentate-mucronulate, teeth or mucronulae 1–3 per side, apex acute to rounded, surfaces short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, gland-tipped. |
Flowers | plesiogamous, (1–)3–12, from medial to distal nodes. |
Styles | glabrous. |
Corollas | white to pinkish or flesh colored, rarely yellowish, throat and abaxial lobes red-spotted, nearly radially symmetric; tube-throat cylindric, 5–6(–8) mm, exserted beyond calyx margin; limb barely widened, lobes broadly obovate, apex rounded. |
Fruiting pedicels | straight, 11–28 mm, short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, gland-tipped. |
Fruiting calyces | purplish, prominently 5-angled, tubular-campanulate or ovoid-ellipsoid, strongly inflated, 8–12 mm, margins distinctly toothed or lobed, short stipitate-glandular or sessile-glandular, hairs 0.1–0.3 mm, gland-tipped, lobes pronounced, erect. |
Capsules | included, 6–7 mm. |
Anthers | included, glabrous. |
Erythranthe latidens |
|
Phenology | Flowering Apr–Jun. |
Habitat | Drained flats or slopes subject to vernal inundation, depressions in open fields, bare clay soils, vacant lots, roadsides. |
Elevation | 10–800 m. (0–2600 ft.) |
Distribution |
CA; OR; Mexico (Baja California)
|
Discussion | The distinction between Erythranthe latidens and E. inflatula sometimes seems arbitrary, perhaps because of gene exchange where they are sympatric in northwestern California. Erythranthe latidens in Oregon is known only from southern Harney County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
