Drosera finlaysoniana

An annual, upright sundew in the Drosera indica group, with long thread-like leaves covered in sticky glands; it was treated as part of D. indica until it was resurrected as a separate species in 2013. It grows in seasonally wet ground across northern Australia and Southeast Asia, and in flood-prone eucalyptus woodland further south, completing its life in the wet season. In cultivation it is grown from seed each year in hot, bright, wet conditions.
