The fruit is much flattened laterally and the two mericarps are rarely equal. The anterior may be almost entirely . aborted and remain sterile; or rather it differs in form, appearance and superficial condition from the posterior carpel which contains first an ovule, then a seed with narrow aliform raphe. Trachymene inhabits Oceania, especially Australia, and consists of herbs often annual, with branches sometimes leafiike. Xanthosia and Siehera, also Austra- lian, resemble the above especially in the flattened fruit. In the former (fig. 165) the sepals are well developed, wide, cordate, bilobed. Fig. 165.
