Comprehensive Description

This panic grass is quite hairy. It is also rather variable as different varieties have been described with varying degrees of success. According to Mohlenbrock (1973/2001), the typical variety of White-Haired Panic Grass has culms and sheaths with widely spreading hairs, ligules that are 4-5 mm. long, and leaf blade upper surfaces that have appressed long hairs. Another variety, Dichanthelium villosissimum pseudopubescens, has culms and sheaths with appressed to ascending hairs, ligules that are 2-3 mm. long, and leaf blade upper surfaces that are either glabrous or short-hairy. However, some specimens of this grass display characteristics that are a mixture of these two varieties. Unlike Mohlenbrock, some authorities regard Dichanthelium praecocius as a variety of White-Haired Panic Grass, or Dichanthelium villosissimum praecocius. Generally, White-Haired Panic Grass can be distinguished from other panic grasses by its hairy foliage, hairy spikelets, the size of its spikelets (2.0-2.5 mm. long), and the width of its vernal leaf blades (4-10 mm. across).
