Flowers usually hermaphrodite,regular, 4—5-merous (in trop. African 
species). Calyx-tube adnate to the ovary, sometimes produced more 
or less above; lobes valvate. Petals as many as calyx-lobes, fugacious, 
contorted or imbricate. Stamens usually as many or twice as many as 
calyx-lobes. Ovary inferior, usually 4- or- 2- celled; ovules axile, in- 
definite or solitary. Fruit a capsule, often thin or membranous, dehis- 
cent by valves or irregularly, or (in Zrapa) a nut. Seeds indefinite or 
solitary, exalbuminous or nearly so.—Herbs or rarely shrubs, often 
aquatic. Leaves opposite or alternate, entire or toothed, stipulate. 
Flowers axillary, usually solitary. 
A considerable Order, common to both hemispheres, and most abundant in the North

I cannot at present feel clear as to this.
