Drosera platystigma

black-eyed sundew

Drosera platystigma, the black-eyed sundew, is a pygmy sundew of south-western Western Australia described by Lehmann in 1844. It forms small rosettes, spreads by gemmae, and grows through the cool wet winter before resting through summer. It is widely recorded (over 200 wild records), so the measured climate is a sound guide.
