The staminate flowers are long and asymmetrical with three linear, triangular sepals, basally connate and adnate to the receptacle.

Synapomorphies such reduced staminate flowers, advanced wood anatomy features, and the presence of spermidines in pollen define the Coryloideae.

24.

Both marine and freshwater forms include those with staminate flowers that detach from the parent plant and float to the surface where they become pollinated.
28.
Polygamous plants may have bisexual and staminate flowers ( andromonoecious ) or bisexual and pistillate flowers ( gynomonoecious ), or both ( trimonoecious ).
29.
The flowers are arranged on the rachillae such that the pistillate members are proximal, with 5-13 staminate flowers at the distal end.
30.
The staminate flowers mature from green to yellow, triangular in bud, with three sepals fused into a lobed cupule and three valvate petals.
