Professor Swartz's representation of the subject, in his excellent treatise, just come to my hands in English. See Tracts relative to Botany translated from different Languages (by Mr. König), printed for Phillips and Fardon, 1805. I have already, p. 272 mentioned the glutinous nature of the pollen of these plants. This forms yellow elastic masses, often stalked, in each cell of the anther, and the cells are either parallel and close together, or removed from each other to the opposite sides of the style: which serves to connect them, just as the filament does in many Scitamineous plants, alike therefore decided to be monandrous. Such a decision with regard to those also is justified by the analogy of other species, whose cells being approximated or conjoined, properly constitute but one anther. The grand and absolute subdivision of the Orchideæ is justly founded by Dr. Swartz, after Haller, on the structure of the anther, whether it be, as just described, parallel, like that of Orchis, Engl. Bot. t. 22; Ophrys, t. 65; Diuris, Exot. Bot, t. 9, &c.; or ver-
