Snake Range bladderpod |
white bladderpod |

Habit | Perennials; caudex simple; densely pubescent, trichomes 5–7-rayed, rays bifurcate or trifurcate. | Annuals (winter); with a fine taproot; sparsely pubescent, trichomes (minute), 3- or 4-rayed, rays furcate or, sometimes, trifurcate. |
Stems | several from base, erect or outer usually decumbent toward base, (from below a terminal tuft of mostly erect leaves, unbranched), 1–2 dm. |
few to several from base, erect, (from basal leaf cluster, branched distally, flowering branches slender, subtended by bracts), 3–6 dm. |
Basal leaves | blade ovate to elliptic, 2–4 cm, (base gradually narrowed to petiole), margins entire, (surfaces densely pubescent with trichome layers). |
blade oblanceolate or broadly obovate, to 10 cm, margins usually sinuate-dentate or entire, sometimes lobed. |
Cauline leaves | (remote, proximal shortly petiolate); blade spatulate to oblanceolate, similar to basal, (base often cuneate), margins entire. |
(proximal shortly petiolate, distal sessile); blade oblanceolate to narrowly oblong, similar to basal, (distal with base slightly cuneate). |
Racemes | elongated. |
paniculate, (rachises and pedicels more densely pubescent than proximal leaves). |
Flowers | sepals linear-oblong, 5–7 mm, (lateral pair subsaccate); petals (erect), lingulate, 8–10 mm, (claw barely differentiated from blade). |
sepals elliptic, 3–7 mm, (median pair slightly thickened apically, cucullate); petals (white), broadly ovate, to 12 mm, (narrowing gradually to short claw). |
Fruiting pedicels | (recurved), 7–10 mm. |
(widely divaricate-ascending and straight, or slightly recurved), 10–15 mm, (slender, pubescent). |
Fruits | (usually pendent, sessile), subglobose, slightly flattened (angustiseptate), 4–5 mm; valves densely pubescent, trichomes somewhat spreading; ovules 8–12 per ovary; style 4–5 mm. |
(widely spreading to nearly pendent in age, shortly stipitate), globose or subglobose, not or slightly inflated, 3–10 mm; valves (not retaining seeds after dehiscence), glabrous; replum as wide as or wider than fruit; ovules 8–12 per ovary; style ca. 2 mm, (slender, fragile). |
Seeds | plump, (mucilaginous when wetted). |
flattened. |
