Description
Drosera brevifolia is a carnivorous plant.
Generally, for the Drosera genus, they are an "annual or a perennial, rosulate, scapose herbs. Leaves with tentacle-like, glandular trichomes, the glistening, sticky secretion of each gland contributing to the insect-catching function of the leaf, and to the common name. Flowers perfect, actinomorphic, 5-merous; sepals and petals persistent, enclosing the capsule; stamens 5; ovary syncarpous, superior, 1-locular. Capsule valvate, seeds minute." - Radford et al 1964.
Specifically, for. D. brevifolia, the species has "leaves that are obovate to spatulate, cuneate, 7-16 mm long including the indistinct petiole. Scape glandular pubescent, 2-6 cm long; pedicels and calyces glandular pubescent; corolla white, sometimes tinged with pink, 5-7 mm long. Seeds black, irregularly obovoid, less than 0.5 mm long, minutely reticulate." - Radford et al 1964.
Distribution
Ecology
Habitat
D. brevifolia occurs in moist to wet, sandy or peaty soils (FSU Herbarium). It also seems to prefer more open conditions that provide higher light levels (FSU Herbarium). It can be found in longleaf pine communities,[1] pine-saw palmetto flats, open glades, and at the margins of marshes, grass-sedge bogs, ponds, and swamps (FSU Herbarium). It also occurs in some disturbed areas that are moist and open, including power line corridors, cutover pinewoods, roadside ditches, open fields, and mowed lawns (FSU Herbarium).
Associated species include Aristida stricta, Helianthus radula, H. heterophyllus, Pinguicula lutea, Drosera capillaris, Sarracenia psittacina, Polygala, Pinguicula pumila, Utricularia, longleaf pine, pine, saw palmetto (FSU Herbarium).
Phenology
Flowering has been observed in March through May (FSU Herbarium).
Seed dispersal
It is found in the seed bank of disturbed and non-disturbed sites.[1]
