Drosera reflexa is a newly described sundew in the D. microphylla complex. The species is named after its strongly reflexed petals and sepals.
Drosera reflexa is a small erect tuberous sundew that usually reaches around 15 cm in height. The stem and leaves are green-red in colouration. The petioles are arching, and the stem is somewhat flexuous in that it changes direction at each leaf axil. The laminae are more or less orbicular and the leaves occur singly. The flower buds are encased by proportionally large sepals which are crimson in colour. The petals are a moderately light shade of pink throughout, tending darker towards the center. The styles are a deep crimson.
The species grows on seasonally moist moss beds on granite outcrops. It is only known from a single population between Walpole and Albany, making it one of the most endangered carnivorous plants.
Drosera reflexa is closely related to 8 other species within the Drosera microphylla complex. These plants are united by large sepal buds, erect stems and small, rounded laminae. The range of the species overlaps with D. microphylla. It is distinguished from D. microphylla by its pink petals (those of D. microphylla are a reddish orange). It is somewhat similar to D. esperensis in foliage and floral morphology. It is distinguished from D. esperenses by its darker pink petals (those of D. esperensis are white with pink centers. D. esperensis also grows several hundred kilometers to the east).
