We went camping last weekend on the Oregon coast and made a quick stop to see these pitcher plants. When we got home I pulled out this copy of The Carnivorous Plants that my grandfather owned and found some neat illustrations of Darlingtonia. So I thought I’d put a photo with the illustrations. You can view more photos here.
There is a second class of plants which, as we have just seen, cannot digest, but absorb the products of the decay of the animals which they capture, namely, Utricularia and its close allies; and from the excellent observations of Dr. Mellichamp and Dr. Canby, there can scarcely be a doubt that Sarracenia and Darlingtonia may be added to this class, though the fact can hardly be considered as yet fully proved.
