Descripción: Árbol de 5 a 15 m de alto. Tronco recto y cilíndrico. Corteza exterior negra. Ramitas terminales largas, delgadas y cubiertas de pelos hirsutos. Hojas simples y alternas, de 6-15 x 2-5 cm, lanceoladas a oblongas, con ápice acuminado, bordes enteros o ligeramente revolutos por el envés y base redondeada. Las hojas se encuentran cubiertas de pelos y presentan puntos negros en ambos lados de la nervadura central del envés. Pecíolo de 0.3-0.5 cm de largo y ligeramente acanalado en la parte superior. La especie es dioica. Flores blancas. Frutos globosos, de 3-5 cm de diámetro, verdes, tornándose amarillos al madurar.

Datos Ecológicos: La especie crece a bajas y medianas elevaciones, en bosques húmedos o muy húmedos. En Panamá se encuentra en las provincias de Colón, Darién, Panamá y la comarca de Guna Yala. Florece y fructifica de mayo a septiembre.

Especies Parecidas: A menudo se confunde con LK guatdo Guatteria dolichopoda LK2 y LK guatdu Guatteria lucens LK2 , pero en Guatteria las hojas no tienen puntos negros en el envés y los frutos son monocarpos.

Usos: La madera es empleada para leña.

Slender dioecious tree, ca 4-15 m tall, to ca 20 cm dbh, unbranched for much of its length; smaller branches long and drooping; most parts moderately to densely hirsute (especially dense on young parts), the upper blade surfaces, petals, and inner flower parts glabrous. Petioles 5 mm long; blades lanceolate to oblong-lanceolate, narrowly acuminate, obtuse to rounded at base, 6-14 cm long, 2.5-4 cm wide (larger in South America), glabrous above except on midrib. Staminate flowers in short axillary cymes, usually only one flower opening at a time; pubescence of branches, pedicels, and calyces crisp-villous; buds narrowly ovate; calyx campanulate, to 3.7 mm long, appressed-pubescent inside except near base, the lobes 6, irregular, triangular, extending one-third to one-half the way to base; corolla white, ca 1 cm long, lobed to near base, the lobes 6, somewhat imbricate, thick, 4 mm wide, with a longitudinal line of sparse pubescence somewhat off-center outside, this diminishing at about middle, the apex asymmetrical and recurved at anthesis; stamens ca 35-40, to 2.7 mm long; filaments less than 11 mm long, narrowed at apex, pubescent along inner side, the trichomes stiff, straight, translucent, extending entire length of connective; anthers apiculate at apex, the connective prolonged one-third to one-half the length of the thecae. Pistillate flowers in ca 5-flowered axillary cymes, subsessile or with pedicels to 5 mm long; corolla and calyx like staminate flowers; staminodia ca 6; ovary ovoid-conical, ca 4 mm wide and long; styles 4 or 5, ca 4 mm long, divergent, united only at base; locules 8 or 10; ovules 1 per locule. Berries subglobose, 8-celled, hispidulous, to 4 cm diam; seeds 8 or 10 or fewer by abortion, ca 20 mm long and 9 mm wide, ca 6 mm thick, black, the endosperm smooth; fruiting calyx scarcely accrescent.
