Frequently lateral flowers are aborted and their place is occupied by simple or branched prickles, or tufts of hair, which persist till the fruit is ripe and serve as a means of distribution, the partial inflorescences becoming detached from the main axes, as in Fig. 44 Celosiaargentea.

Seed cut length- wise; c, cotyledons; r, radicle; perisperm. (From Flor. Jam.) The structure of the flower corresponds with that of Chenopodiaceae. As a rule, a simple generally regular 5-merous perianth is followed by an opposite whorl of five stamens, while a unilocular superior ovary with one, two or three styles occupies the centre of the flower. The membranous perianth-leaves are free or more or less united; they may become woody at the base enclosing the fruit. They are often hairy; in species of the AustraUan genus Ptilotus the long silky hairs form wind-floats. The stamens are generally united below into a membranous tube, which may bear simple, lobed or fringed, petaloid outgrowths between each.
