Description
This species is strongly glaucous.[2]
Generally, for the Eragrostis genus, they are "annuals or perennials from short rhizomes or hardened bases. Glumes similar, shorter than lowest lemma. Florets more than 2. Lemmas 3-nerved, paleas persistent, ciliate."[3]
Radford (1964) explains that E. elliottii is similar to E. refracta. And states that the "lateral spikeletes shorter than pedicels, not appressed."[3]
Distribution
E. elliottii is distributed along the southeastern Coastal Plain from North Carolina south to Florida and west to Texas.[1] It is also native to the U.S. Virgin Islands.[4]
Ecology
Habitat
Generally, this E. elliottii can be found in maritime wet grasslands, Ultisol wet pine savannas, inland edges of brackish marshes and freshwater tidal marshes, and calcareously-influenced wet pine savannas.[1] It does well in open canopy areas on longleaf pine habitats.[5] Sandhill community.[6] Does not do well in highly disturbed areas (such as clear cutting).[5] This species has also been observed to occur in sand ridges of longleaf pine and turkey oak woodlands, clearings in coastal hammocks, marshy boarders of cypress-gum ponds, oak woodlands, interdune depressions, sandy prairies, and open grassy limestone glades. It does well in areas of high light intensity to partial shade in loamy sands, drying sands, moist shell sands, and peaty sandy soils.[2] It is also considered an indicator species of the peninsula savannas in Florida.[7] It is also more commonly found in native groundcover in longleaf pine savannas rather than old fields.[8]
Associated species include Panicum flexile, Eustachya,[Habenaria ciliaris, Balduina uniflora, Lilium catesbaei, Eriocaulon decangulare, Rynchospora, Aristia, Eragrostis hirsute, Pinus palustris, Quercus laevis, Stenaria nigricans, Sporobolus junceus, Schoenus nigricans.[2]
Eragrostis elliottii is an indicator species for the Peninsula Savannas community type as described in Carr et al. (2010).[9]
Phenology
This species generally flowers from September until October.[1] It has been observed to flower and fruit in October and December.[2]
Seed bank and germination
This species was found to persist in the seed bank after a fire disturbance.[10]
Fire ecology
This species lives in environments that are burned.[2] One study found that seeds of this species persisted in the seed bank after a fire disturbance.[10]
Herbivory and toxicology
Eragrostis elliottii is considered to have good foraging value.[11] Cattle can graze on this species in the early spring, and E. elliottii tends to increase in abundance under grazing.[12]
Diseases and parasites
It is a common host plant of the fungus Balansia epichloe in the southeastern United States.[13]
