Herbs acaulescent; caudex branched. Flowering stems 30-50 cm, short or long stipitate-glandular. Leaves: petiole glabrous or long stipitate-glandular; blade reniform or rounded-cordate, shallowly 5-lobed, 2-6 cm, base cordate, lobes rounded, margins dentate, apex obtuse, surfaces long stipitate-glandular on veins abaxially, glabrous or short stipitate-glandular adaxially. Inflorescences dense. Flowers: hypanthium radially symmetric, free 1-1.8 mm, cream or yellowish green, broadly campanulate, 3-5 mm, short stipitate-glandular; sepals erect or incurved, green-tipped, equal, 0.6-1.2 mm, apex ovate; petals usually erect, white, elliptic, (not clawed), unlobed, 0.5-1 mm, margins entire; stamens included 0.5 mm; (filaments erect or incurved distally, equaling and not concealed by anthers); styles included 0.5-1 mm, 0.5-1 mm, 0.1+ mm diam. Capsules ovoid, 5.5-6.5 mm, beaks divergent, not papillose. Seeds dark brown, asymmetrically ellipsoid or convex-fusiform, 0.5 mm. 2n = 14.
Flowering Jun. Shaded rocky ledges and outcrops; 1800-2200 m; Ariz., N.Mex.
Heuchera novamexicana occurs in the mountains of Arizona and New Mexico. Populations with glabrous petioles may be found in the Organ Mountains of New Mexico; elsewhere, long stipitate-glandular petioles are more common in the species.
The Navajo Indians took a decoction of roots of Heuchera novamexicana for internal pain. They applied a poultice of split roots to infected sores, swellings, and fractures, and used the plant as a panacea or 'life medicine' (D. E. Moerman 1998).
Plant: Perennial herb
Leaves: blades 2-6 cm long, circular-cordate, moderately 7-10 lobed, the lobes crenate; petioles usually densely glandular hairy to hirsute, 2-15 cm long
INFLORESCENCE: contracted elongate panicles, almost racemose above, 30-40 cm tall
Flowers: 4-6 mm long, cream to yellow-green, glandular puberulent; portion of hypanthium fused to ovary 1-2 mm long, ovoid, shorter than free part; sepals equal, oblong-ovate, occasionally green-tipped, erect; petals 1.5-2.5 mm long, more or less equal to sepals, narrowly oblanceolate; stamens shorter than sepals, the anthers yellow; mature styles shorter than sepals
