Dalbergia pervillei is a deciduous shrub or tree growing up to 18 metres tall. The bole can be up to 60 cm in diameter[
The plant is harvested from the wild for local use as a medicine and source of wood.
Although Dalbergia pervillei is locally common in Madagascar, it occurs mainly in lowland forest, a habitat that is under much pressure because of the growing human population and the resulting demand for agricultural land. Moreover, it is also locally selectively felled for its valued timber and exploitation rates have increased in the early 21st century. The plant is classified as 'Vulnerable' in the IUCN Red List of Threatened Species(2019)[
Africa - western Madagascar.
Broadleaved, deciduous, seasonally dry forest and woodland, usually at elevations between 50 - 300 metres[
|Other Uses Rating||
Found in the wild on limestone, sands or sandstone soils, and also on ferralitic soils derived from gneiss and migmatite[
]. In cultivation they are likely to do well in a fertile, loam soil and a position in full sun[
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 reddish exudate from the plant is used in the treatment of laryngitis[
The wood is used for carpentry and for making furniture[
The wood is used for fuel.
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 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[
Softwood cuttings of many species, especially if taken from younger plants, will root in a well-drained, sandy medium in a closed case with bottom heat[
