The name Debregeasia edulis (treated here as a synonym of Oreocnide frutescens (Thunb.) Miq.), appears to have been misapplied to Debregeasia velutina (which itself is now viewed as a synonym of Debregeasia longifolia (Burm.f.) Wedd.) by most authors since Weddell in 1859[]. Some of the reports here were listed under Debregeasia edulis and are likely to more correctly refer to Debregeasia longifolia. The reports in question are clearly marked in the text below[].

Common Name: Wild Rhea

Agroforestry Uses:

The tree is planted as a pioneer species in northern Thailand in reforestation projects to restore native woodland - it is planted in degraded woodland and open areas in a mix with various other species that all have the ability to grow fast; produce dense, weed-suppressing crowns; and attract seed-dispersing wildlife, particularly birds and bats[].

Other Uses

A strong fibre is obtained from the stem bark[, ]. Of high quality[]. It is used for making twine and rope[, ].

Wood is used mainly for fuel[].

Propagation
