Plants
perennial, with stout rhizomes. Aerial stems 20–70 cm long, erect or ascending,
moderately pubescent with mostly downward-pointing nonglandular hairs. Leaves
basal and 1 or few opposite pairs on the stems, the basal ones long-petiolate,
those of the stems short-petiolate. Leaf blades 4–15 cm long, wider than long,
depressed-ovate to bean-shaped in outline, deeply 5-lobed, the lobes more or
less obovate, mostly sharply pointed at the tip, the margins more shallowly
lobed and sharply and coarsely toothed, the surfaces moderately pubescent with
nonglandular hairs, those of the upper surface sometimes becoming sparse with
age. Inflorescences appearing axillary or less commonly terminal, long-stalked,
paired, loose clusters of 2–9 flowers. Individual flower stalks 10–30 mm long,
1.5–4.5 times as long as the sepals, pubescent with spreading to
downward-pointing nonglandular hairs. Sepals 6–9 mm long, not becoming enlarged
at fruiting, elliptic-ovate, tapered to a short awnlike extension 1.5–3.0 mm
long at the tip, pubescent with a mixture of spreading to somewhat
downward-pointing shorter nonglandular and longer glandular hairs. Petals 12–23
mm long, broadly obovate, rounded to very slightly notched at the tip, pink or
rarely white. Stamens 10. Staminodes absent. Mericarps 25–40 mm long at
maturity, the seed-containing basal portion 3.5–4.0 mm long, the lateral
surfaces smooth, moderately to densely pubescent with spreading nonglandular
hairs 0.2–0.6 mm long, lacking a dorsal ridge or wing, the stylar beak with
spreading to loosely ascending nonglandular hairs, the slender extension
between the columnar portion and the stigmas 5–8 mm long. Seeds 2.5–3.0 mm
long, the surface with a fine network of ridges and pits. 2n=52.
April–June.
Scattered to
common nearly throughout the state (eastern U.S. west to North Dakota and
Oklahoma). Bottomland forests, mesic upland forests, banks of streams and rivers,
and shaded ledges of bluffs).
This is a
conspicuous and common spring wildflower of bottomlands. It is sometimes
cultivated as a garden ornamental. Rare white-flowered plants have been called
f. albiflorum (Raf.) House.
