Name:
Latin, hordeum, barley. (Jaeger 120).
Latin, lepor, a hare and inum, like.
(Jaeger 126, 139). Leporinum
probably refers to the inflorescence being like a hare's foot or perhaps the
hare's tail. (John Johnson).
General:
Very common in the study area. Photographed
on the North Star Flats. (my
comments). In Calif., H. leporinum, is
the most abundant of the wild barleys. As
early as 1890, Hilgard described this plant as "a fearful nuisance" in
central California. As a group, the
wild barleys are mechanically injurious grasses; the mature beards may bore into
the skin, or the mucous membrane of the mouth, causing ulcers.
The seeds, which resemble a barley grain but are narrower and flatter,
are scattered by water, by wind and carried by animals, to which they cling by
reason of the barbed awns. (Robbins
et al. 82-83). Hordeum
species have been known to cause hay fever and asthma.
(Fuller 383).
About 25 species of temperate regions.
