Description
Dichanthelium oligosanthes is a perennial graminoid. It tends to form dense tussocks of many stems (FSU Herbarium).
Distribution
Ecology
Habitat
It can live in Foard and Lawton soils, which are both grassland soils.[1] D. oligosanthes var. scribnerianum can tolerate hot summers, cold winters, minimal precipitation (826 mm per year), and moderately strong surface winds.[2] It seems to prefer light levels between open sun and partial shade (FSU Herbarium).
This species can be found in undisturbed areas.[3] It is commonly found in open woodlands[4] and tallgrass prairies.[2] D. oligosanthes also occurs in oak-pine flats, limestone glades, sand plains, loblolly pine forests, upland pine woods, and oak hammocks (FSU Herbarium). However, it can also be found in disturbed habitat like cut over pine woods, cultivated and old fields, roadsides, railways, and disturbed prairies (FSU Herbarium).
Associated species include Rudebeckia triloba, Panicum virgatum, Andropogon scoparius, Koeleria macrantha, Ambrosia psilostachya (FSU Herbarium).
Phenology
It flowers from early to mid season.[5]
Flowering has been observed in May, while fruiting has been observed in March, May, and June (FSU Herbarium).
Seed dispersal
Fire seems to stimulate the seed bank.[4]
Seed bank and germination
Fire ecology
It responds positively to fire. It increased in distribution and abundance following an early dormant-season fire.[4] Dichanthelium oligosanthes var. scribnerianum found in uplands and lowlands responded positively to summer burns but negatively to spring burns in the long run (more than 10 years). However, D. oligosanthes found in the canopy cover declined with both burns.[2]
