Lycophylls and euphylls.

Description
(a) Most lycophylls possess only a single unbranched leaf vein having limited conduction capacity, explaining why lycophylls are generally quite small. (b) Euphylls possess branched vascular systems having greater conduction capacity, explaining why many euphylls are relatively large. (c) Fossil evidence suggests how pteridophyte euphylls might have evolved from branched stem systems.
