Phleum phleoides (common names: Boehmer's cat's-tail and purple-stem cat's-tail) is a perennial grass native to most of Europe, North Africa, and temperate Asia. Culms are erect and 10– in height; leaf blades are 5– long by 1– wide.[1]
It can be confused with related species Timothy-grass, Phleum pratense. However purple-stem cat's-tail prefers lighter soils and grows on chalk downland.[2]
