Ferreirea spectabilis Allemão
Sweetia fruticosa is a deciduous tree with a large, very open, globose crown; it can grow 10 - 18 metres tall. The straight, cylindrical bole can be 40 - 60cm in diameter[
The tree is harvested from the wild for its durable wood and for local medicinal use.
S. America - Paraguay, Brazil, Bolivia, Peru.
Atlantic rainforest and broadleaved semideciduous forests, almost exclusively in dense primary formations and seemingly indifferent to the physical condition of the soil[

Prefers a position with some shade[
]. Succeeds in a wide range of soils[
A slow-growing tree, able to reach a height of around 1.5 metres within 2 years from seed[
Although many species within the family Fabaceae have a symbiotic relationship with soil bacteria, this species is said to be devoid of such a relationship and therefore does not fix atmospheric nitrogen[
The wood contains a peculiar powder which is highly recommended as a remedy for fevers[
The bark is a source of tannins[
The wood is medium-textured, irregular-grained, heavy, hard, resistant to the attacks of wood-eating organisms. It is used for fine cabinet work, veneer, lathe work, doors, balconies, wainscotings, door and window frames, posts, railway sleepers, poles etc[
Seed - it has a hard seedcoat and may benefit from scarification before sowing to speed up 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. Sow the seed in a partially shaded position in a nursery seedbed or in individual containers. A germination rate of more than 30% can be expected for freshly sown, untreated seed, with the seed sprouting within 20 - 30 days[
]. When the seedbed-sown seedlings are 4 - 6cm tall, pot them up into individual containers and they should be ready to plant out 6 - 7 months later[
