Cirrhose = with a tendril. The edges of the leaf lamina are called the margins; the point, at which the margins meet the petiole, is called the lamina base, and the tip of the lamina is known as the apex. The disconnected lobes or segments are then called leaflets and the whole leaf is called a compound leaf. The veins also support the lamina.
