Proteales is an order of flowering plants consisting of three (or four) families which has been recognized by almost all taxonomists. The representatives of the Proteales can be very different from each other – the order contains plants that do not look alike at all. What they have in common is seeds with little or no endosperm, and the ovules are often atropic. The anthophytes are a grouping of plant taxa bearing flower-like reproductive structures. They were formerly thought to be a clade comprising plants bearing flower-like structures. The group contained the angiosperms - the extant flowering plants, such as roses and grasses - as well as the Gnetales and the extinct Bennettitales.
