Capsules ovoid to short-ovoid or subglobose, 4-6(-7) x 3.5-5.5(-6) mm, lepidote, otherwise moderately to densely pubescent, the pale, very thick sutures separating as unit from adjacent valves; seeds 1.5-2.7 mm long.
Distribution. Endemic to Cuba (Prov. Oriente;
Sierra Maestra, Gran Piedra range, and few mountains of eastern Oriente),
in pinelands, thickets, rocky places, moist montane forests, "monte fresco"
vegetation of higher summits, at ca. 650-2000 m elev.

Leaf blades ovate or broadly ovate to elliptic or nearly orbicular, 2.5-6.5(-8) cm long; base rounded to slightly cordate or broadly cuneate, not decurrent; adaxial surface with midvein usually slightly depressed, 2o veins usually at least slightly depressed, especially on larger-leaved plants; abaxial surface with 3o and higher order veins ± flat or nearly so and obscure to slightly and laxly reticulate, in plants from extremely high elevations near or at summit of Pico Turquino, raised, forming dense, fine reticulum; petiole 4-12(-14) mm long, pubescent adaxially only. Pedicels 2.5-5(-7) mm long. Flowers with calyx lobes (3-)3.5-7(-8) mm long.
Distribution. Endemic to Cuba (Prov. Oriente,
Sierra Maestra from Loma del Gato westward), in pinelands of Pinus maestrensis,
low to tall thickets, moist montane forests ("Fangales"), rocky areas,
"monte fresco" vegetation of higher summits, at ca. 700-2000 m elev.
Flowering probably mainly April to July.
