Drosera rotundifolia

Today’s photographs were taken over seven years ago, with my first digital camera.

Lindsay Bourque wrote today’s entry:

Native to lowland temperate Asia, Europe and North America, this species is commonly known as round-leaf sundew. Drosera rotundifolia inhabits areas with little available nutrients. To survive, it catches insects with sensitive, sticky glandular leaf hairs. Once an insect is stuck in the mucilage, the leaf hairs partially enfold the insect. Proteolytic enzymes are then secreted to dissolve the prey, with the nutrients derived from the insect absorbed by the leaves to feed this insectivore.

For more photographs of round-leaved sundew, including close-ups of both the flowers and the glandular leaf hairs, see the Burke Museum’s page on Drosera rotundifolia.

    A facinating plant I wish I could find in my area. Beautiful images!

    Great pix, Daniel. I know from experience how hard they are to photograph. It’s always a treat to find sundew.

    Given the season, a timely photo. The trailing vine in the upper photo appears to be cranberry.

    I was just reading about this amazing adaptation in “Botany for Gardeners”. This one’s leaf hairs are so beautiful.

    I am always intrigued by the latin/greek names given to plants and always want to know what they mean. It is not often such information is included. It the case of this sundew it
    Drosera, from the Greek, droseros meaning dewy ,watery and rotundifolia from the Latin, rotundus meaning round, spherical and folius meaning
    leaf.
    I think this information should be included with all you plants names/descriptions.

    Did my undergrad thesis on this species (and a couple of others). Still delighted every time I see it. I’ve found it growing in a relatively wide variety of habitats, it is fairly tolerant compared to some Drosera species.
    Agree that it can be hard to get a good picture of both leaves and flower scapes in focus, have often had to lie down on the (sometimes damp) ground!

    I know that when I found this gem growing in the thousands at the bottom of a quarry in New England in an area flooded by flowing spring water, I thought that the reason it was able to survive the below zero N.E. winters was because of the temperature of the spring water, and the fact that it was covered with a roof of snow, which would act as insulation. Until today, I never realized that it was so winter hardy as to survive in North Dakota (-42 degrees F at times).
    Does anyone know what mechanism this delicate looking jewel uses to cope with such temperatures?

    Great picture! I found these growing in an upland bog at Dolly Sods (West Virginia) among the cranberries. But they were so tiny I couldn’t get a good picture.

    Adolf Ceska sent this photograph along, with the commentary: “ATTACHED is my photo of Drosera rotundifolia. It was also taken with my first digital camera and I did not know what I was doing.”
    (I think he’s being too humble, as usual)
