(By A. B. RENDLE.) 
Flowers unisexual, moncecious or dicecious (polygamous in Parie- 
taria), regular or, especially in the female, irregular. Male flower: 
Perianth generally 4-5-partite, more rarely monophyllous, calycie ; 
segments concave, sometimes mucronate or appendaged beneath the 
apex, valvate or imbricate ; stamens generally equal in number and 
opposite to the sepals (solitary in Forskohlew), inflexed in bud; 
anthers 2-celled, introrse, opening longitudinally ; rudiment of ovary 
variously developed. Female flower: Perianth 3-5-lobed or partite 
with equal or unequal segments, or tubular, calycine, persistent and 
very often increasing after pollination; ovary free or sometimes 
adherent to the tubular perianth, 1-celled ; ovule solitary, attached 
at or near the base of the cell, erect or ascending, orthotropous ; 
style rarely developed, simple; stigma capitate and tuft-like or | 
penicillate, or more or less elongated ; staminodes absent or scale 
like and inflexed, opposite the sepals. Fruit small, an achene, 
invested at the base or more or less enveloped by the persistent 
perianth, which is generally dry and membranous, sometimes succu- 
lent ; albumen scanty or absent; embryo straight, with thick 
flat, generally broad cotyledons.—Annual or perennial herbs, shrubs, 
sometimes climbing, or more rarely trees, sometimes with stinging 
or sharply pointed hairs, often with dot-like or linear cystoliths. 
Leaves alternate or opposite, the members of a pair often unequal, 
simple, generally penninerved ; stipules 2, persistent or deciduous, 
lateral or axillary, free or united, absent in Parietaria. Flower 
small, cymose, often in small clusters which are sessile or arranged 0 
lax inflorescences, sometimes crowded on a fleshy or open receptacle, 
sometimes subtended by an involucre of bracts. 
Species about 500, natives of temperate and tropical regions, especially the
