---|---|---|---|---|---|---|
roundleaf bladderpod |
|
|||||
Habit | Perennials; caudex simple or branched, (thickened by persistent leaf bases); densely pubescent (foliage usually scabrous), trichomes (sessile or short-stalked), several-rayed, rays furcate near base, (usually strongly umbonate, roughly tuberculate, less so over umbo). | Annuals, biennials, perennials, or subshrubs; eglandular. | ||||
Stems | few to several from base, erect or outer decumbent, 0.5–2.5 dm. |
|||||
Basal leaves | blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate. |
|||||
Cauline leaves | (proximal shortly petiolate, distal usually sessile); blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire. |
petiolate, sessile, or subsessile; blade base usually not auriculate (except Paysonia), margins entire, dentate, or sinuate. |
||||
Racemes | compact, (± subumbellate to densely corymbiform, elongated or not). |
ebracteate, often elongated in fruit. |
||||
Flowers | sepals ± elliptic, 4.5–7(–8.5) mm, (median pair thickened apically); petals (sometimes white), suborbicular to obovate or obdeltate, 6.5–15 mm, (base narrowing to broad claw, apex sometimes emarginated). |
actinomorphic; sepals erect, spreading, ascending, or reflexed, lateral pair seldom saccate basally; petals white, yellow, lavender, purple, violet, orange, or brown [pink], claw present, often distinct; filaments unappendaged, not winged; pollen (3 or) 4–11-colpate. |
||||
Fruiting pedicels | (usually spreading at right angles, sometimes nearly erect, ± straight), 5–15(–20) mm, (stout). |
|||||
Fruits | (sessile or shortly stipitate, less than 1 mm), subglobose to broadly ellipsoid, inflated or slightly compressed (terete or subterete), (4–)5–8(–9) mm; valves (not retaining seeds after dehiscence), glabrous; replum as wide as or wider than fruit; ovules 8–16 per ovary; style 4–8(–9) mm. |
silicles or siliques, dehiscent, unsegmented, terete, latiseptate, or angustiseptate; ovules 2–100 per ovary; style usually distinct; stigma entire or strongly 2-lobed. |
||||
Seeds | flattened. |
biseriate, uniseriate, or aseriate; cotyledons accumbent or incumbent. |
||||
Trichomes | usually short-stalked, subsessile, or sessile, sometimes long-stalked, stellate, scalelike, subdendritic, or forked, sometimes mixed with simple ones. |
