Stamens in [4 or]5 fascicles, free and antipetalous , or some united to form apparently 4 or 3 fascicles with compound fascicle(s) antisepalous , or irregular and apparently not fasciculate, persistent or deciduous, each single fascicle with up to 70[-120] stamens; filaments slender, free from nearly base [or to 2/3 united] or apparently completely free; anthers small, dorsifixed or ± basifixed , dehiscing longitudinally, with gland on connective ; sterile fascicles (fasciclodes) absent [very rare]. Ovary 3-5-loculed with axile placentae or ± completely 1-loculed with (2 or) 3[-5] parietal placentae, each placenta with [2 or] few to many ovules; styles (2 or) 3-5, free or partly to completely united, ± slender; stigmas small or ± capitate.
