sheep mountain bladderpod

mid-bladderpod

Habit Perennials; caudex branched, (thickened, cespitose); densely pubescent, trichomes 5- or 6-rayed, rays slightly fused at base, furcate or bifurcate, (tuberculate throughout). Perennials; caudex (buried), branched, (thickened with persistent leaf bases, cespitose); densely pubescent (usually grayish-green), trichomes (sessile or short stalked, spreading), several-rayed, rays furcate or bifurcate, slightly fused at base, (tuberculate or finely tuberculate).
Stems

few from base, well-exserted from basal leaves, 0.4–1(–1.2) dm.

several from base, erect to decumbent, (unbranched, stout, densely leafy sterile shoots sometimes present), (0.5–)4–2.5 dm.

Basal leaves

blade (erect), obovate to orbicular, 1.5–2.5 cm, (base evidently distinct from petiole), margins entire, (folded).

(clustered at stem base);

blade linear to linear-oblanceolate, 2–5 cm, margins entire, usually involute, sometimes flattened, (apex obtuse to subacute).

Cauline leaves

blade spatulate, margins entire.

blade linear-oblanceolate to linear, 1–3.5(–4.5) cm, margins entire, usually involute.

Racemes

compact, subumbellate.

compact, (often nearly subumbellate).

Flowers

sepals (pale yellow), 4–5 mm;

petals lingulate, 6–7 mm.

sepals (yellowish or greenish yellow), ovate or oblong, 4.5–7.5(–9) mm, (lateral pair sometimes cucullate, median pair tapering at both ends, thickened apically, cucullate);

petals spatulate or oblong, 6.5–10.5(–15) mm, (base sometimes widened, apex rounded or retuse).

Fruiting pedicels

(ascending, curved to slightly sigmoid), 5–8 mm.

(often expanded distally, ascending or recurved, usually straight or slightly curved, rarely nearly sigmoid), 4–15 mm, (stout).

Fruits

ovoid to ellipsoid, slightly inflated, (apex not compressed), 3–4 mm;

valves pubescent, trichomes erect on mature fruits, (± appearing fuzzy);

ovules 8 per ovary;

style 4–5 mm, (glabrous).

(sessile or substipitate), subglobose to slightly ovoid, usually inflated, rarely compressed or obcompressed, 4–6(–10) mm, (apex acute, slightly flattened);

valves sparsely pubescent, trichomes appressed;

ovules (8–)12–16(–20) per ovary;

style (2–)3–4.5(–5.5) mm.

Seeds

plump.

flattened.

Discussion

Of conservation concern.

Physaria eriocarpa is known from Sheep Mountain.

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

N. H. Holmgren (2005b) pointed out that the lectotype and other material from New Mexico, where Physaria intermedia is very infrequent, is quite similar to P. parvula from northern Colorado and northeastern Utah; it is also quite similar to, but less robust than, P. pulvinata from southwestern Colorado. The material from Arizona, northwestern New Mexico, and Utah may represent an unnamed taxon; further study is needed.
