A small family of insectivorous plants found in bogs or moist sandy soil.
Thread-Leaved Sundew (Drosera Filiformis) has long, linear, film-like, erect, very hairy leaves. The flowers are numerous and loosely racemed at the top of a slender smooth scape; they have five, small, purple petals, five stamens and several 2-parted stigmas. The flowers open only in the sunshine and bloom towards the top of the scape, where a number of undeveloped buds droop. This species is found in wet sandy soil from New England to Delaware, not far from the coast
A. Thread-leaved Sundew.
B. Round-leaved Sundew.
Round-Leaved Sundew (Drosera Rotundifolia) is one of the most common of the Sundews; it is found in moist, sandy or peaty soil from Labrador to Alaska and south to Pa. and Cal. The leaves are numerous, quite round, and on long stems from the root. The leaves are thickly covered with hairy glands, that exude drops of a clear glutinous fluid, glistening in the sunlight like little drops of dew; it is from these that the plant is named. These dewlike drops deceive insects into alighting on the leaves, when they discover, to their dismay, that they are held fast prisoners in the sticky fluid. Having caught a victim, the leaf slowly folds about it and more slowly digests it.
The flower stalk of this species grows from 5 to 9 in. high, is reddish colored and often has one or two branches at the top. The one to twenty five flowers that it has during the flowering season are white. They open but one or two at a time, and only in bright sunshine. The leaves, and also the short rootstalk, have rather purplish juices that stain what they come in contact with. While they are small and inconspic-uous, one will find it well worth while to study these plants.
