Like the blade the anther is divided into two longitudinal halves, called lobes, by a mid- rib, called the connective, which is usually grooved in the upper surface or face (ventrum) of the anther, and ridged on the lower surface or back (dorsum), as in leaves. The mode of attachment of the filament to the anther varies in different plants: thus it is (i) innate or basifixed—B when the filament is attached to the base of the anther so that the connective is the direct prolongation of the filament, as in Poppy and Mustard; (2) adnate or dorsifixed—a when the fila^ ment is attached to the connective at the back of the anther, as in dulee-champa {Magnolia); and (3) ver-.
