is a perennial carnivorous plant that forms one or more rosettes, with mature plants raised from the ground on a sort of bulb-like arrangement, formed by the accumulation of the old leaves. It grows in white sandy unconsolidated soil on flood ways or near river swells and rocky outcrops in Beverly Springs, Derby, Erskine Range, Gibb River, Prison Tree and Winjana in the region of Kimberley, Western Australia.
Its green oblanceolate petioles are both erect and semi-erect that are covered in white woolly non-dendritic hairs and divides into many rosettes from its root stalk. They are narrow and are even more narrow just before the lamina. The lamina is orbicular in shape and the colors range from pale red, red, pale orange or orange. The glandular hairs on the upper side are longer at the edge but shorter in the center, densely covered with white non-dendritic hairs on the lower surface.
Each rosette produces 1–4 raceme inflorescence, which are 10–14 inches long. Each inflorescence bears 30–50 white or pink flowers, accuring from March to June. The top of the flower scape and the bottom surface of the sepals are densely covered in white, non-dendritic hairs
This species was first noticed On 29 March 1988, in Boab Prison Tree, 0.4 mi from Derby, the area from which this species is named. D. derbyensis is closely related to Drosera lanata, but differs from that species by the non-dendritic hairs covering the leaves.
(Name origin: from the city of Derby, in Western Australia).
