Description

It is the tallest-growing species in the pea family, Fabaceae and one of the tallest tropical tree species in any family, reaching 60 m (200 ft) and taller. The unarmed trunk is cylindrical, the bole of larger specimens 15–22.5 m, up to 3 m in diameter at soil level. The DBH of mature specimens is typically between 80 to 200 cm (31 to 79 in), moderately to strongly buttressed, the buttresses to 4–5 m tall.[7][5]

The heartwood is reddish brown with a slightly paler sapwood. The wood is durable and difficult to work with due to its density and irregular grain.[4]

Distribution and habitat

It is found in Guyana, Suriname and Amazonia Brazil (in the northern and central-western states of Amapa, Amazonas, Mato Grosso, Para, Rondonia, Roraima and Tocantins). Also recorded from the state of Acre by Lorenzi (1992).[8]

The species grows in non-inundated moist and upland mixed forests known as "floresta ombrofila mista", tropical forest on "terra firme", tropical upland evergreen forest, and tropical dry forest.[7] It has been recorded at elevations from 50 to 490 m.[7]

Tallest tree

The tallest measured specimen is 88.5 m (290 ft) with a circumference of 5.5 m (18 ft), which is believed to be about 400 years old, discovered near Jari River in Inipuku (municipality of Almeirim, Para state) in 2019.[9][10] The discovery was made using airborne laser scanning (ALS) and field verification in Paru State Forest, which is shared by the Brazilian Amazon basin states of Amapa and Para.[11][12][13] On the 7th of October 2022 a group of researchers reached the tree and measured a circumference of 9.9 meters.
