| Distribution | New Hanover County. A single specimen is known: "old fields", October 17, 1935, P.O. Schallert s.n. (DUKE). The specimen was annotated from A. virginicus by H. DeSelm and C. Campbell.
Coastal Plain, southern SC to southern FL and northwestern FL; disjunct to NC. | |
| Abundance | Formerly very rare; no record in many decades, and now must be considered as historical (SH). The website editors recommend a Significantly Rare status. As its habitats seem numerous in southeastern NC, it could be re-found one day. | |
| Habitat | "Old field." Weakley (2018) states "Dry sandy soils of sandhills and dunes" for the Southeastern states. The BONAP map shows its distribution north of FL as being limited to coastal counties in NC, SC, and GA -- thus to be looked for on dunes and sandy places close to the shore. | |
| Phenology | Flowering and fruiting September-October. | |
| Identification | The identity of the sole NC specimen should be double-checked. Long-beard Bluestem looks much like Broomsedge (A. virginicus) [strict sense] but the hairs on the leaves are mostly appressed to the surface (vs. smooth or with spreading hairs in that abundant species). | |
| Taxonomic Comments | None. Not included in RAB (1968).
While the genus Andropogon is quite easy to recognize in the field, ID of species is not so easy and there are no shortcuts. Readers are strongly advised to read the introductory paragraphs in Weakley (2018) and to use his key. Once one has successfully keyed out several species, or compared collections with verified specimens, one can learn to recognize them in the field. | |
| Other Common Name(s) | Hairy Bluestem (used on this website for A. hirsutior) | |
