Description:
Description: Rhizomatious subshrub to 0.5 m tall, erect and unbranched to poorly branched, bark thin, not well developed; twigs moderately to densely pubescent, with regularly chambered pith; buds to 2 mm long, leaves revolute. Leaves alternate, subopposite, or nearly 3-whorled; coriaceous, (1.5-)3-4.3 x (0.6-)1.5-2.7 cm, ovate, base rounded to cordate, apex broadly acute to acuminate, margin entire, slightly revolute, adaxial surface lacking gland-headed hairs, otherwise sparsely pubescence along midvein, abaxial surface lacking gland-headed hairs, otherwise glabrous to sparsely pubescent along midvein, with a few inconspicuous glandular dots along midvein; petiole 2-8 mm long. Inflorescences axillary (or terminal) racemes to 2-2.5(-4) cm long; rachis densely pubescent; pedicels 4-8 mm long, densely pubescent; bracteoles 2, alternate or opposite, ± basal, linear, to 2.5(-4.5) mm long; floral bracts to 2(-2.7) mm long. Flowers with triangular calyx lobes, with acuminate apices, (1.7-)2-2.5 x (1.5-)1.8-2(-2.5) mm, abaxial surface densely pubescent; corolla cylindrical, red, 7-10 x (2-)3-4(-4.5) mm, very sparsely pubescent; filaments (4.5-)5.7-6.5(-7) mm long; anthers 1.5-2 mm long; ovary pubescent. Capsules shortly ovoid to subglobose, 4-6.5 x 3-5 mm, placentae subapical; seeds (1.5-)1.7-2.3 mm long.
Distribution: Endemic to Mexico (to a small region in the Sierra de Cuale, W the Zimapán mine, Mpio. Talpa de Allende, Jalisco), in pine-oak forests on rocky soils.
Type: Mexico. Jalisco: Mpio. Talpa de Allende, El Caracol, W of Mina Zimapán, 2200 m elev., 24 May 1987, González V. 3092 (holotype, IBUG, n.v.; isotypes, ENCB, n.v., FLAS, IEB, n.v., MEXU, n.v., NY, n.v., US, n.v., WIS, n.v.).
