The flowers are borne in dense axillary spikes, with each individual flower having five sepals, five petals, and ten stamens. The fruits are twisted or coiled pods, up to {{convert|15|cm|0|abbr=on}} long, containing several coffee-coloured seeds inside.

Distribution and habitat

It has been introduced into Hawaii, where it is now commonly found growing in thickets behind beaches.{{cite book|contribution=Prosopis chilensis|title=Firewood Crops: Shrub and Tree Species for Energy Production |contribution-url=https://books.google.com/books?id=XmQrAAAAYAAJ&pg=PA148 |year=1980 |publisher=National Academies of Sciences|location=Washington, D.C.|page=148 |id=NAP:14438}}

Uses

Neltuma chilensis is used as a shade tree and for firewood. The leaves are used as fodder for livestock and the pods and seeds are of high nutritive value and are ground to make an animal feed.
