Sand Grass


Triplasis purpurea (Walt.) Chapm.

Sand-grass, thick and rigid of leaf, is a tufted plant of the beaches, and, like a few other salt-water grasses of the Atlantic coast, it is also found on Western ranges.

It is very different in appearance from such species as Marram Grass, Bitter Panic-grass, and Creek Sedge, which also grow by the shore, but like them it does not bloom until late summer.

Many stems, usually less than two feet tall, spring from one root and bear very short, narrow, rough leaves. The panicles, also, are short, with but a few stiff branches, and bear loosely flowered, rose-purple spikelets.

The outer scales are smooth but the flowering scales are fringed and bearded, presenting a distinguishing feature by which this grass may easily be recognized, and the acid taste of the plant is also peculiar to it.
