A foxtail is a spikelet or spikelet 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 and other domestic animals, and a nuisance for people. ==Sources== The name "foxtail" is applied to a number of grasses that have bushy spikes of spikelets that resemble the tail of a fox. Not all of these are hazardous; most of the hazardous ones are in the genus ''Hordeum'', and are also called "wild barley". Grasses known as foxtails include: * ''Alopecurus'' (foxtail grasses - the scientific name literally means "fox tail") * ''Bromus madritensis'' (foxtail brome) * ''Hordeum jubatum'' (Foxtail Barley) * ''Setaria'' (foxtail millets) Other grasses also produce hazardous spikelets. The spikelets are sometimes called foxtails, even though the grasses are not. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Foxtail (diaspore)」の詳細全文を読む スポンサード リンク
