Abstract

The Averrhoa Carambola of Linnæus, a tree called in Bengal the Camruc or Camrunga, is possessed of a power somewhat similar to those pieces of Mimosa which are termed sensitive plants; its leaves, on being touched, move very perceptibly. In the Mimosa the moving faculty extends to the branches; but, from the hardness of the wood, this cannot be expected in the Camrunga. The leaves are alternately pinnated, with an odd one; and in their most common position in the day-time are horizontal, or on the same plane with the branch from which they come out. On being touched, they move themselves downwards, frequently in so great a degree that the two opposite almost touch one another by their under sides, and the young ones sometimes either come into contact or even pass each other.
