Description

Subshrubs to 1.5 m tall, unbranched, the stem terete, glabrous, the nodes well spaced, the petiole scars hemispherical or oblong, 0.5-1.2 cm long. Leaves rhom- boid, 16-33 cm long, 6-16 cm wide, acute or deltoid toward the apex, acuminate, the acumen scarcely developed, cuneate or acute toward the base, the costa prominulous above, prominent beneath, the lateral veins 12-14, rigid, not arcuate, forking near the margin or with 1 or 3 small veins near the margin, the submarginal undulate vein lacking, the intervenal areas minutely lineolate, glabrate above, puberulent on the costa and the veins beneath, rigidly papyraceous, slightly dis- colorous; petioles 2.5-6.0 cm long, those in the middle ca. 0.3 cm wide, puber- ulent and twisted; stipules ovate lanceolate, to 3 cm long, to 1.1 cm wide at the base, subcoriaceous, glabrous, with 2 keels on the back toward the base, well spaced but converging toward the apex, glanduliferous within toward the base, the small glands oblong, to 1.5 mm long. Inflorescences axillary, the flowers few, the peduncle shorter than the flowers and with short scales; bracts red, crowded, deciduous, numerous, imbricate, perhaps binate, narrowly oblong, to 1.8 cm long, to 0.8 cm wide, scarious on the back, puberulent or glabrate, ciliate, glabrous within; bracteoles beneath the hypanthium oblong rotund, 8-12 mm long, oth- erwise like the bracts. Flowers with the hypanthium ca. 2.5 mm long, white puberulent, the calycine cup cylindrical, 3.5-10.0 mm long, densely minutely pubescent or glabrate within below the sinuses, the lobes 5, ovate oblong, ca. 8 mm long or longer in fruit, obtuse, glabrous within, coriaceous; corolla white or light yellow; stamens 5, the anthers oblong, to 2.5 mm long, the filaments slender, 9.0-11.5 mm long, villose at the base, arising ca. 7 mm from the base of the tube; style slender, ca. 15 mm long, the stigmas widely oblong, ca. 2.5 mm long, plano compressed, obtuse. Fruits sessile, oblong to rotund, to 3.5 cm long, yellow toward the base, at first rugulose then moderately smooth, the calyx red, at first persistent, to 2.5 cm long, ultimately wrinkled except for the calycine cup.

Note
|
It is characterized by its small size and its small rhombic leaves, although a recent indeterminate col- lection by Mori & Kallunki (6184) from Escuela Agricola Alto de Piedra, Vera- guas, resembles this species. It is in fruit and is described by the collectors as a "slender unbranched tree, 4 m tall, 4 cm dbh." Its leaves measure to 40.5 cm and are deltoid at the apex. Unfortunately flowers were not collected.
