| Distribution | Mostly the Piedmont, and scattered in the low elevations in the Mountains. Gaps in the map are likely to be filled in with additional collecting.
N.S. to MN, south to GA, LA, and TX. | |
| Abundance | Fairly common to frequent in the Piedmont, but uncommon in the Mountains. Probably often overlooked. | |
| Habitat | Open disturbed woodlands, mafic glades, Post Oak--Red Cedar barrens, roadsides, powerlines. In dry to xeric soils, poorly tolerating any competition. |
| Phenology | Flowering and fruiting August-November. | |
| Identification | Poverty Dropseed is a small species, 6 inches to 1.5 feet tall, with slender, delicate stems and leaves, and overall a gray-green color. The lower part of the plant sometimes is bent to the ground. Inflorescences grow at stem ends, are slender, and are dull red-brown color. It is told from S. ozarkanus by the glabrous bases of the leaf sheaths (vs. hairy bases in S. ozarkanus). | |
| Taxonomic Comments | This taxon is very close to Ozark Dropseed (S. ozarkanus), and the latter taxon is lumped into S. vaginiflorus by some authors.
Recent molecular research suggests that Calamovilfa and Spartina are nested deeply within Sporobolus. Weakley (2020) proposes that they remain split until a long-term solution is found, as their members are monophyletic. | |
