Alfaroa manningii, or gavilán colorado, is a valued lumber tree of the Walnut family endemic to the premontane Costa Rican rain forest.
[2] Alfaroa manningii grows to 24 m tall, with a diameter at breast height up to 0.9 m, and small to medium large buttress roots.
The hard shell is deeply furrowed, with eight to twelve sharp longitudinal ribs running from the tip to the equator.
Alfaroa manningii is distinguished from the similar A. guanacastensis by its generally larger leaves (both longer petioles and more leaflets) and large fruits with a thick, heavily corrugated glabrous shell.
)[3] Alfaroa manningii is only known from a small area in Costa Rica near Rio Platanillo in the northeastern province of Cartago.
