It was communicated by Mr. Donn, Curator of the Cambridge Botanic garden, and is to be enumerated in the new edition of his Catalogue now in the press. It requires to be kept in the bark-bed in the hot-house, and is supposed to be a native of the Isle of France. We believe no other figure of it has been given. [Illustration: [Plate 554]] PLATE DLV.
