Description:
Description: Herbs or subshrubs, 1.5-3.5 dm tall (to 4.4 dm in fruit). Leaves lustrous, elliptic, ovate-lanceolate, ovate to widely ovate, or suborbicular, 2-6.5(-7.5) x 1.5-4(-4.7) cm, basally acute and often slightly decurrent on the petiole, apically acute or obtuse, often obscurely mucronate, margin minutely and remotely crenulate, surface discolorous, dark green above, brownish or coppery-red below; petioles channeled above, smooth, 1.3-6.5 cm long, reddish-brown. Inflorescences usually solitary, erect, 5-18-flowered; scape terete, (1.3-)2.1-3.5 dm tall, smooth; scape bracts membranaceous, subulate to lanceolate, 1.2-2.5 x 0.2-0.4 cm, base auriculate to clasping, apex acute, margin entire to slightly crenate, strongly costate, reddish-brown; flower-bearing portion of scape 4-11.5 cm tall, elongating in fruit, smooth; pedicels terete, smooth, 5-9 mm long, elongating in fruit, reddish-brown; bracts subtending the pedicel membranous, subulate to broadly lanceolate, acute or long-acuminate, longer than the pedicels, 8-12(-15) x 2-3 mm, margin entire to crenulate, reddish-brown, persistent. Flowers strongly sweet-scented; calyx 4-6 mm long, the lobes lanceolate, ovate-lanceolate, or ovate, bases not overlapping, apices acute, acuminate, or obtuse, 3.5-5 x 1.2-2 mm, margin crenate, green (?); corolla 0.7-1 cm long and 1.4-1.5 cm diam., the petals obovate or obovate-elliptic, 0.8-1.1 x 0.5-0.7 cm, entire to slightly crenate; stamens 6-8 mm long; filaments ca. 6 mm long; anthers 2.2-3 mm long; tubes 0.2-0.5 mm long; thecae reddish-brown (?); ovary subglobose; style 6-10 mm long, somewhat thickened above; stigma ca. 1 mm diam. Capsule 4-5 x 6-8 mm.
Distribution: Found on moist, mossy (rarely dry, grassy), N- or NW-facing slopes in Abies-Pinus, Alnus-Pinus, Pinus, and mixed Pinus-Quercus forest in the high mountains of south-central Mexico (the Neovolcanic Belt) and south of the Isthmus of Tehuantepec in the mountains of Chiapas and western Guatemala at elevations of 1700-3400(-3700) m. Flowering May through Sep; fruiting Aug through Feb.
Type: Mexico. Veracruz: "Pic d'Orizaba," 2923 m, Jun-Oct 1840 (fl), Galeotti 4223 p.p. [lectotype, designated by Dorr (1995d): K; isolectotype, BR].
