This, the Platy-cerium alcicorne, is a native of Australia. Among the fine representative plants brought by Mr. Charles Moore, of the Sydney Botanic Gardens, to our International Exhibition, one remarkable specimen deserves more than a passing notice, as it is probably the largest and finest of the kind ever brought from its native woods. The plant is the Stag's Horn Fern (Acrostichum alcicorne), and is fully nine feet in diameter. It was discovered encircling the limb of a tree one hundred feet from the ground, and to obtain it a sailor was sent up, who cut off the limb and lowered it to the ground by means of a rope.
