Inflorescence terminal and axillary, mostly leafy, divaricately branched, branches shorter than subtending leaves, glomerules small, ± densely arranged. Flowers bisexual and sometimes female. Perianth segments 5, connate below the middle, prominently keeled near apex, green, sometimes red when old, vesicular hairy. Stamens 5. Stigmas 2. Fruits falling with perianth.
