The sensitiveness to touch of the well-known Sensitive Plant (Mimosa pudica) and Dionaea is singular enough, but the movements of the leaves of this Desmodium seem still more curious, and up to the present have baffled our best observers. The movement may be observed on a light warm day, when the plant is standing in a temperature of about 8o°. The two small lateral leaflets may then be observed to move upwards, and downwards; first the one and then the other, now resting a moment, then starting again with a jerk. The movement is quite spontaneous, the plant not being perceptibly sensitive to the touch. Truly it is a vegetable wonder, and deserves a place in every warm greenhouse on that account. It is easily propagated either by means of seeds or cuttings. It is a rapid grower, and, though it is not handsome, still it is a graceful plant. It grows to a height of about 2 ft. Any light soil will suit it, and the higher the temperature in which it stands the more perceptible are its movements.

I do not think it would thrive in winter in a temperature lower than 550. It is a native of India, and is a member of the Pea family. - Gardening Illustrated.
