A raceme or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard, radish, and orchid plants.

It is native to western North America from British Columbia to Colorado and New Mexico to Baja California, where it grows in many types of open habitat, including grasslands. It is dominant on some grasslands of California, and it was probably an abundant native grass before the habitat was altered by invasive non-native grasses. It occurs on serpentine soils with associates such as serpentine reedgrass. It is also known from parts of South America. It is an annual grass producing one stem or a clump of several stems growing up to 75 centimeters tall. The inflorescence has several open branches bearing clusters of purple-tinged spikelets. The spikelet has one to six flowers. The grass is usually cleistogamous, its flowers fertilizing themselves.
