Natural range of Drosera capillaris from USDA NRCS Plants Database.

Common Name(s): pink sundew[1][2]

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] One predator of D. capillaris is the larvae of the plume moth (Trichoptilus parvulus) which emerge at night to consume the stalked gland of the sundew.[5] Larger larvae may also consume parts of the leaf blade in addition to the gland.[5]
