Taxonomic notes

Description

Dichanthelium strigosum is a perennial graminoid theat tends to grow in thick mats (FSU Herbarium).

Distribution

Ecology

Habitat

It can be found in relatively undisturbed areas,[1] including longleaf pine savannas,[2] saw palmetto-wax myrtle thickets, sandhill ridges, and bogs (FSU Herbarium). However, D. strigosum also occurs in disturbed areas like power line corridors, roadsides, fields, and clear-cuts (FSU Herbarium). This species seems to prefer moist sandy soils (FSU Herbarium).

Associated species include Rhynchospora pusilla, Ludwigia linifolia, Andropogon, Schizachyrium, Eupatorium, Serenoa repens, Juniperus, Schoenus (FSU Herbarium).

Phenology

Flowering and fruiting has been observed in February, as well as April through August (FSU Herbarium).

Seed dispersal

Seed dispersed by gravity.[3]

Seed bank and germination

Fire ecology

It can tolerate biennial, early growing season prescribed fires.[2]
