By suppression i)i certain oases the anther may be reduced to one cell or halved. In Globe Amaranth (Fig. 218) there is a single cell without vestige of any other. Different species of Sage and of the White Sages of California show various grades of abortion of one of the anther cells, along with a singular lengthening of the connective (Figs. 220-22-1)..
