Description:
Description: Inflorescence racemose, rarely reduced to a solitary flower, light yellow to reddish, 5-30 cm high (from root connection), 1-10 mm diam. below lowermost flower, glabrous or variously pubescent; floral bracts elliptic to ovate, 8-15 x 3-15 mm, margins erose, irregularly toothed; pedicels slender, 2-20 mm long, elongating to 30 mm in fruit, 1-2 mm diam., finely pubescent to nearly glabrous, sometimes glandular; bracteoles sometimes present, not consistently so even within populations, to 10 x 5 mm. Flowers cylindric, often constricted distally; calyx distinct from corolla, sepals 4-5 or occasionally absent, 7-12 x 1-5 mm, usually pubescent within; corolla of 4-5 petals divergent at apices, 8-17 x 4-8 mm, oblong to oblanceolate, narrowly saccate at constricted base, rounded to acute at apices, usually reflexed at tip; stamens 8-10 in two series of alternating lengths, 5-14 mm long; anthers hippocrepiform, 0.8-1.5 mm long, each dehiscent by a single terminal slit over the connate sacs; ovary 4-8 x 3-6 mm, usually pubescent, locules 4-5, nectary lobes short, stout, flanking filaments; stigma umbilicate, 1.5-3 mm diam., often subtended by ring of stiff hairs; style uniformly slender, joining abruptly with ovary, 2-10 x 1-2 mm. Capsule 6-10 x 4-8 mm, perianth segments tending to be early deciduous in fruit, capsular segments often irregularly deciduous. Chromosome numbers: 2n=16, 24, 32, 48.
Distribution: In the Neotropics, found in Mexico and Guatemala; forests of Pinus, Abies, and Quercus at 1800-4000 m. Flowering specimens have been collected in May-Feb, but are usually found Jun-Sep.
Type: Lectotype: Specimen in Burser Herbarium (vol. III, fol. 156, UPS, n.v.); suggested as appropriate by Dr. C. E. Jarvis, at BM, (Wallace, pers. comm., 1987).
