Drosera heterophylla

Drosera heterophylla

Drosera heterophylla is an erect tuberous species endemic to Western Australia. It is associated with winter-waterlogged niches such as swamps and the drainage channels of granite outcrops in the Swan Coastal Plain and adjacent Darling Scarp. The species has reniform shaped lamina along a straight main stem and produces particularly lustrous dew. The most distinctive feature of the species is its bloom, which is the only species in the genus to regularly produce many more petals than the usual five (typically 8 – 12)
