Common Name(s): lopsided indiangrass[1][2]

Taxonomic Notes

Synonym(s): Andropogon secundus[2]

Description

Sorghastrum secundum is a monoecious perennial graminoid[2] that grows to 3-6 feet (0.91-1.83 m).[3]

Distribution

S. secundum occurs from southern South Carolina, south to southern Florida, and westward to southern Alabama.[1]

Ecology

Habitat

This species is found on sandhills.[1] In Peninsula Florida Xeric Sandhills, S. secundum was found in 100% of the plots with a mean cover of 0.0299 m2.[4]

Phenology

Flowering occurs in September and October[1] and germination seems to peak in January and February.[5]

Seed bank and germination

In south Georgia, S. secundum buried in seed bags had a 26% germination rate after one year, 34% after two, and 9% after four.[5]

Use by animals

S. secundum consists of 2-5% of the diet for terrestrial birds.[6]

Diseases and parasites

Its seeds are more prone to mold destroying it prior to germination compared to other seeds.[5]
