Habitat

Alfaroa costaricensis normally grows in cloudy areas on well-drained soils with slopes of 5% or more at elevations between 600 and 2200 m which receive 1500–2500 mm of precipitation and sustain temperatures of 15 to 20 °C. This tree does not grow well in the shade.

Description

Alfaroa costaricensis is a slow growing tree with pink heartwood. It can reach 27 m in height and 60 cm diameter at breast height (d.b.h.).^[2]

The seed is a nut, one-chambered at the apex and eight-chambered at the base, which measures 1.6 to 2.5 cm long and 1.4 to 1.6 cm in diameter, and is protected by a hard, thick, brown pericarp. Germination is hypogeal. The leaves are pinnately compound, and are distinguishable from other species by their heavy pubescence. The male inflorescences is a panicle, consisting of approximately ten catkins arranged alternately. The female flowers are sessile on a catkin.^[3]
