Trees to 10 m tall, the branchlets terete, glabrous, the nodes well spaced. Leaves elliptic or obovate elliptic, 18-27 cm long, 6-13.5 cm wide, widely deltoid toward the apex, acuminate, the acumen triangular, 1-2 cm long, basally obtuse, cuneate or truncate, the costa lightly porcate above, prominent beneath, the lateral veins 10-12, arcuate, slender, the intervenal areas spreading reticulate, concolorous, drying green, thin coriaceous, glabrous above, minutely puberulent beneath; petioles 0.3-1.2 cm long, rigid or curved, puberulent; stipules (only one seen) connate?, ovate, to 1.3 cm long, ca. 0.5 cm wide, acute, subcoriaceous, pu- berulent.

Distribution
|
Borojoa atlantica is known only from Panama.
|
Note
|
It is readily distinguished from B. panamensis by the more numerous lateral veins of its leaves and it is from B. patinoi whose leaf blades have still more lateral veins (up to 20). The fruits of the new species and those of B. patinoi are similar. Borojoa atlantica seems closely related to B. universitatis Steyermark, the type of which (Aristequieta 6466; US, isotype) is from the Parque Nacional de Guatopo, 650 m, Venezuela. The lateral veins of B. universitatis number about 18 and the wall of the large fruit (in the dried state) is only about 1 cm thick.
