The ribbed leaves give Pleurophyllum speciosum its name, from the Greek pleuro meaning rib and phyllo meaning leaf. Native to the subantarctic Auckland and Campbell islands, this member of the aster family is a megaherb, forming a rosette more than a meter across with its broadly pleated leaves. The purple flowers grow on stems up to two feet in height. Called the Campbell Island Daisy, it is reportedly related to the Cineraria daisies of Africa. It is considered naturally uncommon, due to its restricted range on the islands.
