Taxonomic Notes
Description
‘’Sporobolus floridanus’’ is a monoecious perennial graminoid.[2]
Distribution
Sporobolus floridanus is endemic to an area from southern South Carolina to peninsular Florida and west through Alabama, but the majority is found in Florida.[3] It can be found in South Carolina, Georgia, Florida, and Alabama.[1][2]
Ecology
Habitat
S. floridanus has been found in sandy pinelands, pine savannahs, marsh edges, longleaf pine-wiregrass flatwoods, and pine woodlands.[4] It is also found in disturbed areas including burned pine flatwoods and powerline corridors.[4]
Associated species: Sarracenia, Macbridea, Cuphea, Verbesine chapmanii, Justicia crassifolia, Rhexia, Liatris, Carphephorus, and Helianthus angustifolius, Anthaenantia, Paspalum, Erianthus, Arnoglossum, Eupatorium, and Bigelowia, and Rhynchospora spp.[4]
S. floridanus is additionally found in wet savannas,[1], seepage bogs, and titi/cypress swamps and is abundant in wet pine savannas.[5] In north Florida mesic flatwoods S. floridanus occurred in 53% of plots with a mean coverage of 0.0613 m-2 and was the sole herbaceous indicator species this community type.[6]
Sporobolus floridanus is an indicator species for the North Florida Mesic Flatwoods community type as described in Carr et al. (2010).[7]
Phenology
S. floridanus has been observed to flower from June through September.[1][8]
Seed dispersal
This species is thought to be dispersed by gravity.[9]
Fire ecology
In Georgia, the percent cover of S. floridanus increased from 0.4% after one growing season following a burn to 1.0% after 8 growing seasons.[10] Populations of Sporobolus floridanus have been known to persist through repeated annual burns.[11][12]
Conservation, cultivation, and restoration
Cultural use
In the past, native peoples would harvest the tiny husk-less grains and grind them into a flour.[13]
