Description
Heteropogon melanocarpus is an annual graminoid.
Distribution
Ecology
Habitat
The soils where H. melanocarpus was encountered during the study are fine sandy loams that are poorly drained with slow surface runoff and medium to very slow permeability.[1] It has also been found in wet to dry loamy sand, and seems to prefer semi-shaded to open light conditions (FSU Herbarium). H. melanocarpus can be found in annually burned savannas, as well as in disturbed habitat such as beside trails, roadsides, railroad beds, old fields, and firebreaks (FSU Herbarium). Associated species include Senna obtusifolia, Conzya pusilla, Strophostyle helvola, Bidens alba, and Andropogon glomeratus (FSU Herbarium).
Phenology
Flowering and fruiting has been observed in July through November (FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire ecology
This species has been found in annually burned savanna (FSU Herbarium).
It was found only in plots receiving periodic winter burning in Lewis and Harshbarger's experiment.[1]
