Amerimnon brasiliense (Vogel) Kuntze
Dalbergia brasiliensis is an evergreen tree with a roundish crown; it can grow 4 - 6 metres tall. The more or less straight and cylindrical bole can be 30 - 50cm in diameter[
The tree is sometimes harvested from the wild for local use of its wood. It can be used as a pioneer species for restoring native woodland and establishing woodland gardens. An ornamental tree, it can be used in landscaping, mainly for street and avenue planting[
S. America - southern and eastern Brazil.
Atlantic rainforest, araucaria forest and savannah, more commonly in dense, primary formations; favouring valley bottoms and the bases of slopes on moist, clayey soils[
|Other Uses Rating||
Succeeds in full sun to moderate shade[
]. Grows in the wild on moist, clayey soils[
Young plants have a moderate rate of growth[
This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[
The tree has a moderate rate of growth, fixes atmospheric nitrogen and is easy to reproduce; it can be used in reforestation projects to restore native woodland and also when establishing woodland gardens[
The wood is thick-textured, fibrous, heavy, hard, with moderate mechanical properties and fairly durable. It is only used locally, for purposes such as beams, scantlings, laths, light cabinet making, door and window frames etc[
Seed - best sown as soon as it is ripe in a partially shaded position in a nursery seedbed. A germination rate of around 50% can be expected, with the seed sprouting within 14 - 20 days[
Like many species within the family Fabaceae, once they have been dried for storage the seeds of this species may benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[
