silver twinpod, west silver bladderpod
|
| Perennials; (compact); caudex branched; densely (silvery) pubescent, trichomes (sessile or short-stalked), 5–8-rayed, rays distinct, furcate or bifurcate, (umbonate, tuberculate and the center less so). |
Perennials; (diminutive); caudex simple or branched, (buried, with thatch of persistent leaf bases distally); (appearing silvery gray-green to silvery purple), densely pubescent, trichomes usually 5 or 6 (rarely 7)-rayed, rays bifurcate or incompletely so, (relatively short, stout, umbonate, moderately tuberculate to nearly smooth, lower layer smoother). |
several from base, erect or outer ones decumbent, (unbranched, stout, usually sparsely leaved), 1–3 dm. |
1–5 from base, prostrate to slightly decumbent, (arising laterally, also erect or ascending from tuft of basal leaves, unbranched, purple-green), 0.08–0.3 dm. |
blade linear, 2–7(–10) cm, margins entire, repand, or shallowly dentate. |
(petiole slightly winged); blade oblanceolate, elliptic, or rhombic, (mostly flat, sometimes somewhat folded), 0.6–2.7 cm, (base tapering to petiole), margins entire, (apex rounded to rounded-acute). |
(sessile); blade (erect), spatulate to linear, (1–)2–3(–4.5) cm, margins entire, sometimes involute, (apex acute or subacute). |
(3–7, shortly petiolate or sessile); blade elliptic to oblanceolate, 0.3–0.5 cm, margins entire. |
dense, (exceeding basal leaves). |
crowded, (ca. 3–7 fruits). |
sepals ovate or oblong, (4.5–)5–6(–7) mm, (lateral pair subsaccate, cucullate, median pair thickened, cucullate apically); petals spatulate, 7–9(–11) mm (widened at base, slightly retuse). |
sepals (greenish yellow), linear-triangular, 3.7–5 mm, (lateral pair subsaccate); petals oblanceolate to narrowly obovate, 4.5–9 mm. |
(spreading, sharply sigmoid), 8–15 mm. |
(ascending, straight), 1.8–3.4 mm. |
(sessile or substipitate), ovate to oblong, not compressed at distal margins or apex, 5–9 mm; valves sparsely pubescent, trichomes appressed; ovules 4–8 per ovary; style 3–5 mm. |
(shortly stipitate, purple or greenish purple in age), slightly didymous, ovoid to obpyriform, 3–5 mm (wider than long, base rounded-obtuse, apex rounded, flattened, or slightly emarginate); valves (inflated, slightly wider than replum), pubescent, trichomes scattered; replum obovate to orbicular-obdeltate, apex rounded, obtuse, or truncate; septum complete or medially small-perforate; ovules 4–6(–8) per ovary; style 2–3.6 mm. |
flattened. |
relatively plump, (ovate to suborbicular, usually rounded on one side, ± flat or concave on the other, not mucilaginous when wetted). |
= 16, ca. 20. |
