Taxonomic Notes
Synonym(s): D. rotundifolia var. capillaris, D. sessilifolia, D. brevifolia var. major, D. minor, D. tenella[3]
Description
D. capillaris is a dioecious perennial forb/herb.[2]
Distribution
Drosera capillaris is found in the southeastern United States ranging from Virginia, south to Florida, and westward to Texas. It can aslo be found in the West Indies, Mexico, and northern South America.[1]
Ecology
Habitat
It is an obligate wetland species[2] being found in pine savannas and other wet sandy or peaty soils.[1]
Phenology
The peak flowering period occurs in April and May.[4]
Seed bank and germination
Emergence of seedlings typically occurs between early winter and late spring.[4]
Fire ecology
The occurrence of fires within the previous year has shown to significantly reduce the proportion of flowering rosettes by half.[4] Burns during the months of May and August produced similar levels of mortality which primarily were caused by burial and shifting sediment related to crayfish chimneys.[4] Such findings suggest fire and carnivory may allow the rapid growth and establishment of D. capillaris in nutrient poor wet savannas.[4]
