Drosera auriculataD. auriculata is an erect and very variable species reaching 15 to 30 cm in height. The colour of stem and leaves may range from green to red. Some variants form a basal rosette from which the stem later will emerge. Others do not form basal rosettes as adult plants. The tubers are mainly white.
The sepals are glabrous which separates D. auriculata from most other species in the complex. The only other species regularly forming glabrous sepals is D. lunata. In addition, Gibson et al also inland forms of D. hookeri with glabrous or nearly glabrous sepals. Nevertheless, both species can be easily distinguished from D. auriculata by the seed shape. D. auriculata has linear seeds 1 to 1.6 mm long. Another typical feature for D. auriculata is that the sepals cover the seed pod losely whereas in most other species in the peltata complex the sepals are tightly clasped around the fruit.
Drosera auriculata as well as all other species in the complex can be easily grown from seeds as the seeds germinate easily and do not require any pre-treatment.
More details on this species can be found Allen Lowrie's Magnum Opus as well as in the recent review of the D. peltata complex species by Gibson, Conn and Bruhl: Austral. Syst. Bot. 25 (1): 75. 2012
