. Freaks and marvels of plant life; or, Curiosities of vegetation. Plant anatomy. MINOR CARNIVORA. 123 the ground.

When fully expanded they fall outwards and lie with their under surface closely pressed to the surface of the soil. The margins of the leaves have long been known to curve inwards in a peculiar manner, but the reason for this curving had not until recently been at all satisfactorily explained. That they did so was an acknow- ledged fact, but why they did so was hardly suspected. The surface of the leaves is clammy, and small objects are apt to adhere to them. It having been observed that insects were often ^^ulcaZuc^d). found sticking to the leaves led to an investigation of the habits of the plant, and its structure. Here, again, we are indebted to Mr. Darwin for a solution of the mystery,. Fig. 17.—Butterwort.
