Grewia flavescens

Grewia flavescens, called rough-leaved raisin, sandpaper raisin, and donkey berry (a name it shares with Grewia bicolor), is a species of flowering plant in the family Malvaceae, native to sub‑Saharan Africa, Yemen, Saudi Arabia, and India.^[2] It is considered to be an underutilized crop, both for its fruit and its use for livestock forage.^[3] Caterpillars of Anaphe reticulata have been found to feed on the foliage.^[4]
