Taxonomic Notes
Variation(s): Dichanthelium villosissimum var. villosissimum; D. villosissimum var. praecocius[1][2]
Description
D. villosissimum is a monoecious perennial graminoid[2] that can be found growing in small clumps.[4]
Distribution
This species is found from Maine and Massachusetts south to Florida and westward to Texas, the Dakota's, Nebraska, Kansas, and Oklahoma. It is also recorded in Oregon and California as well as eastern Canada and parts of Mexico and Mesoamerica.[1][2]
Ecology
Habitat
D. villosissimum is found in dry sandy soils of open woodlands and prairies.[1] In a study comparing mature dry sand prairies, 60 yr and 30 yr successional fields, frequency and average cover decreased with decreasing length of establishment. This suggests it colonizes slowly compared to other species.[3]
Phenology
Flowering and fruiting occur between April and September.[1]
Seed bank and germination
Densities of seeds in the seed banks of Indiana oak savannas averaged a density of 32 seeds per square meter. In secondary dunes, densities had a mean of 45 seeds per square meter.[5]
