Aristiferous
Definition
A niche term used in botanical morphology to describe a plant, a plant structure, or an organ (glume, lemma, fruit) that bears aristas (awns), meaning rigid, prickly hairs or sharp filiform extensions, characteristic especially of grasses. This structural element plays an essential role in protecting seeds against predators and in facilitating their dispersal by clinging to animal fur.
