The flower consists of several leaves, which are placed orbicularly, and expanded in form of a rose; out of whose flower-cup rises the pointal, which afterwards turns to a fruit, composed, as it were, of many seed-vessels resembling husks, which are collected into a sort of head, and full of small seeds. The species are six. Miller.
