Dichanthelium

not marked as a favorite taxon Dichanthelium fusiforme (A.S. Hitchcock) Harvill. Common name: Spindle-fruited Witchgrass. Phenology: May-Nov. Habitat: Longleaf pine sandhills, other dry to moist sand of open pine and pine-oak woods and clearings. Distribution: E. North Carolina south to Florida, west to Mississippi and w. Louisiana (perhaps most abundant in Florida); West Indies; Mexico, Central America, and Venezuela. Previous reports from se. Virginia were based on a misidentified specimen.

Glossary (beta!)

ID notes: Autumnal blades often flat. The autumnal form of D. oligosanthes var. oligosanthes can be very similar to D. fusiforme if the vernal blades of the former are missing. They are best separated by ligule length (0.5-1 mm in fusiforme, 1.5-3 mm in oligosanthes) and the more attenuated ends of the fusiforme spikelet.
