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 and the probability of a rosette flowering is mostly dependent upon its size.[4]
Seed bank and germination
Emergence of seedlings typically occurs between early winter and late spring.[4]
Fire ecology
Fires facilitate the occurrence of D. capillaris by eliminating or reducing competition.[4] Seedling density also increased following burns, although the growth rates of seedlings remained unaffected.[4] Growth rates are instead dictated by level of competition.[4]
Use by animals
Crayfish mound excavations burying individuals of D. capillaris is one source of mortality, especially in smaller individuals.[4]
