tion be right, is properly placed here; but Jussieu doubts it, nor does my dried specimen serve to remove the uncertainty. Stilago proves to be merely the barren plant of Antidesma alexiteria, and belongs to Dioecia; as Sisyrinchium and Ferraria do to Monadelphia, the tubular united stamens of the two last having been mistaken for a solid style. Rhopium of Schreber (Meborea of Aublet, t. 323,) seems therefore the only certain genus of the Order under consideration; unless Lamarck be right in referring to it Jacquin's Strumpfia, upon which I have not materials to form any opinion. The original discoverer attributes to this plant 5 stamens with united anthers; hence it found a place in the Syngenesia Monogamia of Linnæus. Lamarck merits attention, as he appears to have had an authentic specimen. See his t. 731.
4. Tetrandria. Nepenthes, of whose extraordinary kind of leaf mention is made p. 197, is the only genus of this Order in Linnæus, but very erroneously placed here,
