III. Roseae. Erect or decumbent annuals, usually densely furfuraceous. Leaves alter- 
nate, sessile or petiolate, the blades broad, often hastatc, dentate, sometimes glabrate on the 
upper surface. Flowers monoecious, the staminate mostly in simple or paniculate spikes. 
Fruiting bracts sessile or subsessile, broad, united usually to the middle, dentate, the sides 
usually tuberculate.. Radicle inferior or ascending.
