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 subSaharan Africa, Yemen, Saudi Arabia, and India. It is considered to be an underutilized crop, both for its fruit and its use for livestock forage. Caterpillars of Anaphe reticulata have been found to feed on the foliage.
