    • n dionaea A genus of plants, natural order Droseraceæ. Only one species is known, D. muscipula(Venus's fly-trap), a native of the sandy savannas of the Carolinas and Florida. It has a rosette of root-leaves, from which rises a naked scape bearing a corymb of rather large white flowers. The leaves have a dilated petiole and a slightly stalked 2-lobed lamina or appendage with three very delicate hairs and a fringe of stout marginal bristles on each lobe. The hairs are remarkably irritable, and when touched by a fly or other insect the lobes of the leaf suddenly close on the insect and capture it. This is followed by the copious secretion of an acid liquid for the digestion of the prey, and by its absorption. This may be repeated several times by the same leaf.
    • n dionaea In entomology, a genus of dipterous insects. Desvoidy, 1830. Also Dionea.
