 axils of the upper leaves. Sepals 5, equal, regular. Petals 5, 

 mostly equal. Stamens 10, the 5 opposite the petals short and 

 sterile, or reduced to scales, the 5 alternate with the petals longer 

 and perfect, with nectariferous glands at the base of the fila-

 spirally twisted below. Leaves often pinnate and bipinnately 

 parted or lobed, when opposite more or less unequal in size : 

 peduncles terminal or lateral (opposite the leaves or in the axil 

 of the smaller one), umbellately 2-several-flowered with a 4- 

 bracted involucre at the base of the pedicels. Carpels very sharp- 

 pointed below, covered with obliquely ascending appressed hairs, 

 tardily if at all dehiscent. Seeds obconical or oblong, not 

 sculptured.
