Calliandra tubulosa Benth.
Pithecellobium saman acutifolium Benth.
Pithecellobium venosum Rusby
Samanea tubulosa is a deciduous tree with a roundish crown; it can grow 4 - 18 metres tall. The more or less straight, cylindrical bole is 25 - 45cm in diameter with a corky bark[
The tree is sometimes harvested from the wild for local use of its wood. A natural pioneer, it can be used for restoring native woodland and establishing woodland gardens. An ornamental tree, it can be used in landscaping[
This taxon is not currently considered to be threatened or in decline at present. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2012)[
S. America - Paraguay, Brazil, Bolivia, Peru, Ecuador.
Secondary growth areas in forests, gallery forests, and also colonizing open land; favouring moist fertile soils[

Grows best in a sunny position[
], Prefers moist, fertile soils[
A fast-growing plant when young[
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[
A fast-growing natural pioneer species that fixes atmospheric nitrogen, it can be used for restoring native woodland and also for establishing woodland gardens[
The wood is medium-textured, straight-grained, heavy, hard, with moderate mechanical properties and moderately durable. It is only used locally for purposes such as light cabinet making and fence posts[
The wood is used for fuel[
Seed - it has a hard seedcoat and may benefit from scarification before sowing 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. Sow the treated seed in a sunny position in a nursery seedbed. A low germination rate can be expected from untreated seed, with the seed sprouting within 28 - 42 days[
