Drosera burmannii

Drosera burmannii

Drosera burmannii is a rosetted annual species widely distributed from Asia to Australia. It is usually associated with tropical climates, although it can be found down to Sydney, where it inhabits the inland semi-arid plains. The species has distinctive wedge shaped leaves and long snap tentacles. It is highly variable in colour, ranging from bright green to deep red, even at the same location

These photos are taken in early June in the Cumberland Plain of Sydney. The water table this year remains relatively high despite a dry autumn, allowing for the continued en-mass germination of Drosera burmannii at this site in Western Sydney. A higher proportion of specimens are vivid red in comparison to a month ago, perhaps in response to the reduced availability of prey as the weather cools down.

It can sometimes be confused with Drosera glanduligera, another anual species with somewhat similar morphology. Drosera burmannii can be distinguished by the shape of its leaves, which is forms more of a wedge shape, whereas the lamina of Drosera glanduligera is distinctively oval.

The Sydney form is capable of growing rather large given certain conditions. Most of the flowering plants are around 2-3 cm in diameter.
The species forms dense colonies in favourable conditions
The colouration of plants at this site seems to be dependent on environmental factors such as light and the amount of prey.
