often very short, or almost none, with a capitate or 2-lobed stigma. Fruit 
a siliqua or silicule, that is, a pod divided into 2 cells by a thin partition 
from which the valves separate at maturity, or in a few genera the 
is 1-celled or indehiscent or separates transversely into pease joints. 
Seeds without albumen, attached in each cell alternately to the right and 
left edges of the partition. Embryo curved, the radicle rnd mciaebale 
— folded against the edge of the cotyledons — or incumbent — folded over 
the back of one of them. — Herbs or rarely undershrubs. Leaves alter-
