Dichanthelium boscii is a perennial grass that occurs in the eastern United States, from Massachusetts, New York, Kansas and Illinois south to northern Florida and eastern Texas. With a large range extent, more than 300 occurrences, abundant habitat, and broad habitat preferences, this species is considered secure.
Range Extent Comments
Dichanthelium boscii occurs in the eastern United States, from Massachusetts, New York, Kansas and Illinois south to northern Florida and eastern Texas. Range extent was estimated using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024, SEINet 2024).
