== Observations ==

*Annual (''R. vesicarius'') or perennial, mostly very variable herbs, sometimes more than 2 m tall (''R. sagittatus'').
*Leaves spirally arranged, the lower ones mostly in a radical rosette (except ''R. vesicarius''), sheathing at base and provided with an amplexicaul ocrea.
*Flowers in spurious whorls which are combined in racemes or panicles.
*Fruit usually a sharply trigonous samara.

Can be cultivated in the tropics at higher altitudes in fertile soil. For good leaf production, the inflorescences should be removed.
