6, large, fleshy, suborbicular, minutely pitted. Stamens 3; filaments 
joined into a stout column; anthers sessile on the top of the column, 
their tips coherent into a point, their bases diverging. Female 
flowers: pedicel a little longer and stouter than that of the male. 
Sepals in 2 distinct series, subequal, ovate, 14 lin. long, 1 lin. broad,
