---|---|---|
E. W. Berry 1937 | Leaves elongate-oval with acute tips and broadly cuneate or rounded base. Margins with remote and not prominent dentate or serrate teeth, one at the tip of each secondary. Texture subcoriaceous. Length about 9 or 10 cm. Maximum width, at the middle or slightly below, about 3 to 4 cm. Petiole stout, curved, 8 to 10 mm. in length. Midvein stout, prominent, diverging from the midvein at angles of 45° or usually more, slightly curved, subparrallel, craspedodrome, terminating in the marginal teeth. The present species is not unlike various described species of Dryophyllum and is also suggestive of Fagus except for its greater elongation and somewhat curved secondaries. |
