[3] Common names in Malagasy include bojy, boringy, bozy, bozybe, ringy, and za,[4] the last of which gives the plant its specific epithet.

The flower buds are long green cylinders which can resemble oversized beans and could be mistaken for a fruit.

Populations are severely fragmented and numbers are declining due to habitat loss and logging.

It prefers sunny areas and well drained soils, at an elevation up to 800 metres (2,600 ft) above sea level.

[6] Possibly the largest tree of this species (by circumference) grows near Reakaly village north-west from Ampanihy.

Wood may be fed to cattle during droughts and the trunk can be hollowed out to store water.

The bark fibre can be use for cloth or rope and the flowers may be used to sooth sore throats.
