Plants with mostly regular hypogynous 5-merous flowers, 
imbricated sepals and convolute petals, 10 stamens slightly 
monadelphous at the base , the alternate ones shorter, and 5 
pistils cohering to a central prolonged axis, from which 
they separate at maturity by the curling back of the styles 
elastically, carrying with them the small 1 -seeded pods. — 
Calyx persistent. Ovules 2 in each carpel, pendulous, 
anatropous, usually but one ripening. Pods small and

base of the prolonged axis, usually torn open on the inner 
face, when they are carried away by the recurving styles. 
Seed without albumen : cotyledons folded together. — 
Strong-scented herbs (or the Pelargoniums, which have 
somewhat irregular flowers, mostly shrubby plants), with
