Description and Ethnobotany

Growth Form Small herbaceous plant with a fountain-like form.
Foliage The leaf blade is small and round, while the petiole is long and narrow. The leaf blade is densely lined with sticky tentacles bearing mucilage called dew. The dew traps and digests small insects, providing nutrients for the plant. The leaves are arranged in a tight rosette which has a fountain-like form. The petiole or leaf-stalk has whitish hairs known as trichomes which help to trap moisture in the air and increase humidity around the plant.
Flowers Orange flowers are star-shaped and composed of 5 obovate petals. The inflorescence is composed of several flowers that occur on on one side of the inflorescence stalk.
Habitat Occurs in tropical climates with wet-dry seasons and consistently warm temperatures with an average of 30 degrees Celsius that goes up to 40 degrees Celsius or more. During the wet season, there are usually fewer hairs on the petiole than the dry season. During the dry season, the plant may go dormant and the leaves may be replaced by a tuft of hairs. The small-sized leaf blade may be an adaptation to conserve water by reducing the area over which water evaporates and is lost, while the large number of leaves may increase the chance of catching an insect.
Similar This species belongs to a group of about 13 related Drosera species known as the "petiolaris-complex". They all form rosettes and have small, round leaf blades with long, narrow petioles. In nature, members of this group hybridize with one another. Unlike other members of this group, Drosera broomensis does not have hairs on the inflorescence. 
Cultivation This species grows well on acidic, nutrient poor media, such as 2 parts peat and 1 part washed sand.
