In botany, having a small bristle-like extension or awn, as found on some grass seeds and grain heads.
From Latin 'arista' (awn or bristle, possibly connected to Greek 'aristos') + '-ate' (having). This botanical term describes the hairlike projections on cereal grains.
Barley and wheat have these tiny bristles called awns, and botanists call them 'aristulate'—it's a fancy way of saying 'has little whiskers'!
