pinnatifid

The leaves are sessile and pinnatifid, with very narrow segments, and the white flowers grow in solitary heads.

This is another of the downy species, its pinnatifid leaves having quite a woolly appearance.

It differs from the last in having ternate radical leaves with pinnatifid lobes, and the upper leaves, bi-pinnatifid.

They are usually twice pinnatifid, the pinnules being connected by a very narrow foliaceous border along the midribs.

Traillæ, which has “very large bipinnate fronds, all the pinnules pinnatifid.”
