- n. A genus of plants giving name to the order Droseracæ.
- n. Pacific islands, and most abundantly in extratropical Anstralia. Their leaves are covered with glandular hairs, which exude drops of a clear glutinous fluid that glitter in the sun; hence the name Drosera, and in English sundew. These glandular hairs retain small insects that touch them, and other hairs around those actually touched by the insect bend over and inclose it. The excitement of the glands induces the secretion of a digestive fluid, under the operation of which the nutritious nitrogenous matter of the in-sect is dissolved and absorbed. The common European species have long had a popular reputation as a remedy for bronchitis and asthma.
