Queensland forms of Drosera binata are consistently many-times bifurcated and often pink flowered. The species is predominantly found in heathland habitats, mainly in the south east corner of the state. I observed the plants at the Blackdown Tableland and at its northern limit at Byfield National Park.
At the Blackdown Tableland, the plants were bifurcated to around 20 leaf points. Given that it was in mid-autumn, only one plant with active blooms was observed. This flower was a fluorescent pink. At this location, the plants grow around exposed, shallow sandstone creeks at the top of the plateau.
I also observed the species at the Byfield National Park just north of Rockhampton. This location represents the known northerly limit of the species. The plants here grow in remote coastal heathland swamps that are subject to frequent fires. It is only after these fires that the dense swamp growth is cleared and the sundews are accessible.
I observed the species in its post-fire growth phase. In general, Drosera binata adopts a more compact growth phase in response to the influx of sunlight and space. Nonetheless, the plants were larger than the ones I’ve seen elsewhere. The plants had around 15 or so leaf points but are expected to be less bifurcated than plants in unburnt habitat – specimens in the area are known to have over 100 points! The flowers were a mix between fluorescent pink and white.
