From this inferred ancestor there evolved an even larger-leafed clade, in which alveolarity and colleters, as well as quadrangular areoles and an orthogonal reticulum of quintenary veins, developed.
Phlebodium has usually been characterized by venation that is highly reticulate (but free near margins), with 1 to 4 rows of fertile costal polygonal areoles and two or three rows of alternate marginal sterile areoles (without free included veinlets) (Fig.
