|---|---|---|
| J. H. Jones and D. L. Dilcher 1980 | Leaves, simple, symetrical or slightly asymmetrical; margin, entire or slightly crenate; petiole shape, normal (sensu Dilcher, 1974); venation, eucamptodrome without significant marginal looping; midrib moderately thick to stout, straight or slightly curved; secondary veins, moderately thick, sweeping to the margins, branched or unbranched; tertiary veins, at approximate right angles to the midrib, closely spaced, straight, occasionally branched; highest order of venation, fourth rarely fifth; trichomes, absent or when present, always uniseriate and usually unicellular; stomatal complex, anomocytic with 3-7 adjacent epidermal cells, restricted to abaxial surfaces. | |
