plantaginales
An order of flowering plants, division Magnoliophyta (Angiospermae), in the subclass Asteridae of the class Magnoliopsida (dicotyledons). The order consists of only the family Plantaginaceae, with about 250 species. Within its subclass the order is marked by its small, chiefly wind-pollinated flowers that have a persistent regular scarious corolla. The perianth and stamens of the flowers are attached directly to the receptacle (hypogynous) and there are typically four petals that are joined at the base to form a tube. The plants are herbs or seldom half-shrubs with mostly basal, alternate leaves. The common plantain (Plantago major) is a familiar lawn weed of this order.
