Description
Species Description - Subacaulescent, pubescent, ostensibly eglandular perennial herb spreading by creeping roots; stems or scapes 5-10 cm, clustered from vertical rhizomes deriving from woody roots or (and) a vertical, branched rootstalk. Puberulence villosulous, spreading to retrorse or incurved on stems, subappressed on leaflets. Leaves usually contiguous near ground level; leafstalk 2.5-5 cm, the petiole exceeding rachis; pinnae 2-3(-4) pairs usually plus 1, crowded toward end of leafstalk, the terminal 2 or 3 arising together at apex of rachis; leaflets 2-7 pairs, subsessile, crowded and imbricate, obovate-elliptic to short-oblong, somewhat asymmetric, 4-9 mm, 2.2-2.7 r, vaguely punctate under magnification, thick, usually without discernible venation, often with a bluish cast; subulate-filamentous stipels 2-several subtending pinnae attachment, 2 with each leaflet pair. Stipules ovate, chartaceous, persistent, conspicuous on rhizomes. Flowers crowded, numerous in subscapose racemes, declined after anthesis. Pedicels 4-6 mm, not jointed; calyx-hypanthium 8-10 mm, the lobes lanceolate, 6-8 mm; petals golden-yellow, 10-12 mm, obovate, nearly equal (standard proximally red-spotted and blotched, distinctly clawed); stamens slightly longer than petals, filaments ciliate below. Fruits commonly few, indehiscent, soon deciduous, asymmetrically ovate to oblong, straight or slightly curved, flat, 2-5 cm long, 1-1.5(-2) cm broad; valves membranous, canescent, becoming glabrate and reticulate. Seeds 1-4.
