A foxtail is a spikelet or cluster of a grass, that serves to disperse its seeds as a unit. Thus, the foxtail is a type of diaspore or plant dispersal unit. Some grasses that produce a foxtail are themselves called "foxtail", also "spear grass". They can become a health hazard for dogs, cats, and other domestic animals, [1] and a nuisance for ...

During a period of increased humidity during the night, the awns of the spikelet become erect and draw together, and in the process push the grain into the soil. During the daytime the humidity drops and the awns slacken back again; however, fine silica hairs on the awns act as ratchet hooks in the soil and prevent the spikelets from reversing ...

[7] The genus includes over 100 species distributed in many tropical and temperate regions around the world, [8] and members are commonly known as foxtail or ...

A spikelet, in botany, describes the typical arrangement of the inflorescences of grasses, sedges and some other monocots. Each spikelet has one or more florets. [1]: 12 The spikelets are further grouped into panicles or spikes. The part of the spikelet that bears the florets is called the rachilla. [1]: 13
