. The classification of flowering plants. Plants. AMARANTACEAE 103 inflorescence being a simple or branched spike or raceme; or branching occurs in the axil of the bracteoles forming dichasia, which are borne on a simple or racemosely or cymosely branched main axis. 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.
