Placentation is usually known as* free central but it seems to beaxile with the adjacent walls of thecarpels broken down. Traces of thesepta may be seen at the base of theovary. Fruit usually a capsule de-hiscing by apical teeth. The inflorescence is definite form-ing a dischasial cyme, but often one branch outgrows the otherand at length one branch does not develop at all so that acincinnus appears. In some a cincinnus appears from Fig. 267.—Floral diagramSilene venora. 2g6 Plants and their Ways in South Africa Herbs with opposite, usually simple leaves, often stipulate.
