Thus in the Labiatae (fig. 412) and Boraginacese {fig-- 413) the ovaries are free, but the styles, which spring from their bases, become connected and form a central column, which appears therefore as if it were a prolongation of the thalamus. Such an arrangement must not be confounded with that oi the ovaries and styles of the species of Gercmiu-rn (fig. 443), and some other plants, where the axis itself is prolonged in the form of a beak-like process, to which the ovaries and styles become.
