Characteristics

Plants 1–4.5 dm; scape with a few small, scale-like bracts; lvs rounded, with shallow, broadly rounded lobes and with the teeth broadly rounded to a short mucro, more softly pubescent than in no. 1 [Heuchera villosa Michx.]; infl open, the pedicels 3–17 mm at anthesis; fls as in no. 1, but the white (pink) pet narrowly oblanceolate, reflexed, seldom coiled; seeds merely inconspicuously ridged; 2n=14. A rare plant on moist, shaded ledges and cliffs, on sandstone or limestone; W.Va. to N.C. and Ala., w. to s. Ind., s. Ill., Mo., and Ark. July–Sept. Most of our plants are var. parviflora, with spreading-villous stems and petioles and somewhat villous lvs (the upper surface often scantily so), and with the bracts subtending the floral branches toothed and often foliaceous. The Ozarkian var. puberula (Mack. & Bush) E. Wells, with shorter, denser, more glandular pubescence on the petioles, scapes, and lvs, and with the bracts subtending the floral branches entire and scale-like, extends e. occasionally to c. Ky. (H. puberula.)
