DESCRIPTION

Stinkgrasses are winter or summer annuals or perennials, depending on the species and location. At least one dozen stinkgrass species or subspecies occur in California and the western United States. Also called lovegrass, some species have tiny wartlike glands on their leaves and flower spikes, which give off an unpleasant odor. The first seedling leaves are very narrow, light green, and inconspicuous. Their ligule has a fringe of straight hairs with a tuft of long hairs on either side at collar base. A seedling's second and third leaves are light green, short, and roughly 1/10 inch (2.5 mm) wide with tufts of hair arising from base of the third leaf. In addition to often emitting an unpleasant odor, the protruding hairs on the sheath just below the collar (where the leaf base wraps around the stem) helps to distinguish mature stinkgrasses from most other grasses. Flowers occur in multifloreted spikelets, which produce numerous tiny egg-shaped or lens-shaped seed. Plants can be upright, sprawling, or both, and range from a few inches wide or tall to over 3 feet, depending on the species and location.
