On coastal regions of NSW, there is a poorly studied taxon in Drosera section Luniferae. These plants are most similar to D. gunniana in that they possess a strong basal rosette, and are tall.
The characteristics that distinguish it from the standard D. gunniana from inland NSW and south eastern regions of Australia are as follows: The sepal surfaces that are variably hairy with fimbriate sepal margins. These sepal hairs are tipped with a gland (The sepals of D. gunniana are uniformly hairy with non-glandular indumenta). The petal colour is typically rich pink (usually light pink in D. gunniana). I have not examined the seed shape.
The taxon is found in clay-based substrates in coastal regions of central NSW. It usually grows in association with Melaleuca trees on the floodplains of creeks. I have seen the plants in the Cumberland Plain of Sydney and near Newcastle. The plants from the QLD/NSW border region might also represent this taxa but I have not observed those plants sufficiently.
