XXIII, PoLYGAMiA (';, many, yauog, marriage), where the stamens and pistils are separate in some flowers, and united in others, either on the same or two or three diflerent plants. XXIV, Cryptogamia (xgvTiTog, concealed, ya/xog), includes those genera of plants where the stamens and pis- tils are wanting, or at least invisible, commonly called Flowerless Plancs. (46 — 49.) «. Snoh are the twenty-four Linnean classes, in which all the genera of the vege- table kingdom are included. Nothing could have been more simple than the first eleven. To distinguish them, we have only to count the stamens. The otlicr classes are founded upon distinctions less simple, though in general easy to be understood. A good specimen flower of eacli class should here be closely exam- ined, to illustrate the definitions, and fix them in the memoiy. The following simple figures are emblematic of each class, to wliich the pupil is required to apply the appropriate numbers and names. X '1^^.
