Drosera binata, or forked-leaved sundew, is native to Australia and New Zealand. This particular specimen was photographed in the Coromandel in New Zealand.

The flower stalk of this plant was almost 25 cm, holding the five-petaled flowers well above the reddish foliage below. It is usually the foliage of sundews that capture people’s attention; these plants are insectivores and the leaves are covered in stalked glands. Each gland supports a drop of glistening mucilage for the capture and digestion of insects. More images and information about this species can be found via the New Zealand Plant Conservation Network: Drosera binata, or the New Zealand Carnivorous Plant Society: Drosera binata.

Drosera binata stands apart from other sundews in that it has narrow, forked leaves. The leaves may be forked more than once and enthusiasts identify a range of forms. Adrian Slack discusses these forms in his classic book Carnivorous Plants, but this online article also details some of the variation: Drosera binata (PDF). For those interested, the International Carnivorous Plant Society (ICPS) provides some advice on growing fork-leaved sundews.

Drosera is a large genus and there are over 100 species. They are found on every continent except Antarctica, and can range from tight rosettes to upright tufts to climbing stems. For more about the range of species and some interesting evolutionary relationships within the genus, see Drosera phylogeny, also via the ICPS.

    Lovely photos. Reminds me of walks in the “pine barrens” areas of Montauk, Long Island. I saw many beautiful sundews, there. As in your photo, when the sun hit the leaves at the right angle, they glistened as though dusted with diamonds. Such pretty, but lethal little plants. Charming flowers, too.
    Thanks, as always, for your great site.

    Whenever I see these I wonder about the genetics, and whether it is a fairly simple mutation that has turned it from the typical sundew into the branching form. Or has it evolved in a series of stages from the original, which would be surprising as there seems to be no intermediate species.

    Please consider developing a link to Pinerest. I periodically pin you posts on my Be with Beauty Board, but without a pin it button on your site it is a bit time consuming. I pinned today’s

    It would be easier if you had a Pinterest link as you do a Facebook Link.
