|
Habit | Perennials; (cespitose, deep-rooted); scapose; pubescent, trichomes short-stalked, dendritic or irregularly forked, (soft). | Plants with caudex multi-stemmed, ultimate slender stems covered by persistent petiolar remains, terminating in rosettes; sparsely to densely pubescent. |
Stems | erect, unbranched. |
1–4 cm (leafless). |
Leaves | (persistent) basal; rosulate; petiolate; blade margins entire. |
|
Basal leaves | tufted; petiole persistent becoming stramineous, 0.5–1 cm; blades narrowly oblanceolate to broadly linear, 0.5–1.8 cm × 1–2 mm, base attenuate, margins entire, apex obtuse. |
|
Racemes | (corymbose, few- to several-flowered), not or slightly elongated in fruit. |
|
Flowers | sepals (early caducous, erect), oblong, (pubescent), base of lateral pair not saccate; petals white to purplish, oblanceolate, (slightly longer than sepals); stamens tetradynamous; filaments not dilated basally; anthers ovate; nectar glands confluent, subtending bases of stamens. |
sepals purple, 4–5 × 1.5–2 mm; petals 4.5–6 × 1.7–2.3 mm; filaments 3.5–4.5 mm; anthers 0.5–0.7 mm; gynophore obsolete or to 1 mm. |
Fruiting pedicels | ascending to suberect, slender. |
4–15 mm, pilose. |
Fruits | (erect, siliques or silicles), sessile or short-stipitate, lanceolate, broadly oblong to narrowly ovate, not torulose, latiseptate; valves each with prominent midvein and somewhat anastomosing lateral veins, glabrous; replum rounded; septum complete; ovules 10–24 per ovary; stigma capitate. |
1.5–3 cm × 5–9 mm; valves purplish, often glaucous, base obtuse, apex acute to acuminate; style 1–2 mm. |
Seeds | biseriate, somewhat flattened, not winged, oblong to ovoid; seed coat (silvery, papillate), not mucilaginous when wetted; cotyledons accumbent. |

Phenology | Flowering Jun–Jul. | |

Discussion | Species 1. Anelsonia is most closely related to Boechera and Phoenicaulis, from which it is readily distinguished by its scapose habit and papillate seeds. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Anelsonia eurycarpa has been collected from multiple counties in California; in Nevada it is known only from Washoe County and in Idaho only from Blaine and Custer counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
