very leafy, terininated by a globular tuft of small ovate or conical 



heads of flowers, from beneath which usually spring 2—3 or inore 



horizontal branches, In a proliferous manner, each terminated bv a 



head of flowers. This curious mode of growing occasioned the term 



of Herha impia to be applied by the old Botanists to this plant, as If 



the offspring were undutlfully exalting itself above the parents. lu
