Discussion

Eragrostis curvula is native to southern Africa. It is often used for reclamation because it provides good ground cover but, once introduced, it easily escapes. In the Flora region, it grows on rocky slopes, at the margins of woods, along roadsides, and in waste ground, at 20-2400 m, usually in pine-oak woodlands, and yellow pine and mixed hardwood forests.

Eragrostis, a genus of approximately 350 species, grows in tropical and subtropical regions throughout the world. About 110 species are native or adventive in the Western Hemisphere; 25 species are native in the Flora region, 24 are introduced. In most taxa native to the Western Hemisphere, disarticulation is acropetal and the lemmas fall with the caryopses, leaving the paleas attached to the rachilla.

Nathaniel Wolf (1776), the person who first named Eragrostis, made no statement concerning the origin of its name. Clifford (1996) provides three possible derivations: from eros, 'love', and Agrostis, the Greek name for an indeterminate herb; from the Greek er, 'early' and agrostis, 'wild', referring to the fact that some species of Eragrostis are early invaders of arable land; or the Greek eri-, a prefix meaning 'very' or 'much', suggesting that the name means many-flowered Agrostis. Many authors have stated that the first portion of the name is derived from eros, but none has explained the connection between Eragrostis and passionate expressions of love, the kind of love to which eros applies.

EXCLUDED SPECIES

The following species have been reported from the Flora region, but no specimens supporting their presence, other than in experimental plots, have been found: Eragrostis acutiflora (Kunth) Nees, Eragrostis leptostachya (R. Br.) Steud., and Eragrostis suaveolens Becker ex Claus.
