4—5-lobed. Petals 3-7, free or connate or adnate to the staminal tube. 
Stamens usually twice as many as the petals, monadelphous. Disc free.

58. Callitrichaceae. Aquatic or terrestrial herbs. Stems slender, 
often capillary ; leaves opposite and entire. Flowers axillary, monoecious. 
Perianth wanting. Stamen solitary, filament elongated. Pistil solitary ; 
ovary 4-celled; ovules | in each cell. Fruit compressed, 4-lobed, separating 
when ripe into 4 flat carpels. (p. 544.) 
Order Sapindales. 
Trees or shrubs, rarely herbs. Flowers typically pentamerous, usually 
regular. Sepals mostly distinct. Stamens rarely more than twice as many
