frosty bladderpod, Pagosa bladderpod

White Mountain bladderpod

Habit Perennials; caudex simple or branched, (covered with persistent leaf bases); densely pubescent, trichomes (sessile or subsessile), 4–7-rayed, rays furcate or bifurcate, (tuberculate throughout). Perennials; caudex simple or branched; densely pubescent, trichomes (sessile or short-stalked), 6–8-rayed, rays furcate or bifurcate, (tuberculate, less so on outer layers).
Stems

simple or several from base, decumbent or erect, (unbranched), to 2 dm.

simple or few from base, ascending to erect, (0.5–)1–2(–3.5) dm.

Basal leaves

(petiole sharply differentiated from blade, slender);

blade suborbicular or obovate to rhombic, 4–8 cm, (base abruptly narrowed to petiole), margins entire, sinuate, or shallowly dentate, (abaxial surface densely pubescent, adaxial lightly pubescent).

(petiole tapering to blade);

blade rhombic to elliptic and irregularly angular, sometimes spatulate to oblanceolate, 1.5–7.5(–10) cm, margins entire.

Cauline leaves

(proximal petiolate, distal sessile);

blade obovate to rhombic, 0.8–2.3 cm, margins entire or shallowly toothed.

(not or loosely overlapping, petiolate or distal sessile);

blade spatulate to oblanceolate, 1–4 cm, margins entire.

Racemes

dense, (somewhat elongated in fruit).

crowded, elongated.

Flowers

sepals elliptic or oblong, ca. 6 mm, (lateral pair not saccate or subsaccate, cucullate, median pair thickened apically, cucullate);

petals spatulate, ca. 9 mm, (claw expanded at base).

sepals ovate, oblong, or elliptic 4–7.5 mm, (median pair thickened apically, cucullate);

petals spatulate or broadly cuneate, 6–13 mm, (claw slightly expanded at base).

Fruiting pedicels

(horizontal to ascending, sigmoid or slightly curved), 8–11 mm, (stout).

(ascending, curved or sigmoid), 6–12(–20) mm.

Fruits

(sessile or substipitate, often becoming copper-red in age), subglobose or ellipsoid, inflated, 6–9 mm, (firm, glossy);

valves (not retaining seeds after dehiscence), glabrous throughout;

replum as wide as or wider than fruit;

ovules 4–8(–12) per ovary;

style 3.5–7 mm.

(substipitate), globose or obovoid to ellipsoid, sometimes slightly obcompressed, 4–9 mm;

valves (not retaining seeds after dehiscence), glabrous throughout;

replum as wide as or wider than fruit;

ovules 4–24 per ovary;

style (2–)4–7 mm.

Seeds

somewhat flattened.

flattened.

Physaria pruinosa

Physaria pinetorum

Phenology Flowering May–Jun(-Aug). Flowering Apr–Jul.
Habitat Mancos slate or shale, meadows, gentle slopes, edges of ponderosa pine stands Scrub oak, pinyon-juniper woodland, open ponderosa pine forests, these sometimes mixed with Douglas fir, white pine, white fir, Engelmann spruce, or Gambel oak, on limestone-derived or otherwise basic soils, often in rock crevices
Elevation 2100-2600 m (6900-8500 ft) 1400-2900 (-3400) m (4600-9500 (-11200) ft)

Discussion

Of conservation concern.

The one New Mexico population is near the border with Colorado, in Rio Arriba County.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Physaria pinetorum with reduced forms are found at high elevations; in disturbed, moist soils plants can become quite large, as in the Manzano Mountains. Densely cespitose plants with crowded racemes not exceeding the basal leaves are found at the crest (3200–3400 m) of the Sandia Mountains, New Mexico. These probably represent an undescribed taxon.
