Hemiepiphytic tree, to 30 m tall, apparently not a strangler, the trunk ca 1.5 m dbh, buttressed; stems and leaves glabrous; bark pale reddish-brown, lenticellate; sap copious, milky. Petioles 2.5-7 cm long; stipules minutely puberulent to glabrate, ca 7 mm long; blades ovate-elliptic, acuminate, obtuse to rounded or truncate at base, 9-18 cm long, 5-8 cm wide, moderately thin, the major veins in 10-13 pairs, often appearing 3-veined at base, the reticulate veins of lower surface very distinct. Figs paired, turbinate, to 14 mm diam, puberulent, green with brownish spots at maturity; peduncles obsolete or to 4 mm long; ostioles raised; basal bracts 2, semicircular, puberulent, to 3 mm long. Croat 12863. The species was considered to be a synonym of F. citrifolia by DeWolf (1960) in the Flora of Panama, but the two have been shown to be distinct by Ramirez B. (1970), who has made detailed studies of their pollination systems. Though they are morphologically similar and often difficult to distinguish in the herbarium, they are much easier to distinguish in the field, F. dugandii frequently grows along river banks in the Canal Zone, where it is a large tree with the solid trunk indicative of plants that grow from the ground up (or, in the case of fig trees, as epiphytes from near the ground) rather than from the treetops down as in the case of stranglers.
