| E. W. Berry 1937 | Leaves of variable but moderate size, three to five lobate, with broadly cuneate to rounded base, and narrow acuminate lobes separated by rounded open sinuse that extend from 1/2 to 2/3's the distance to the base. Size ranging from lengths of 6 to 10 cm. and maximum widths of 6 to 12 cm. Petiole not preserved. Primaries mediumly stout, prominent, 3 to 5 in number, diverging from the top of the petiole at acute angles in all but one trilobate specimen in which they are suprabasilar. Secondaries thin, numerous, generally straight, their tips connected by flat arches or a true marginal vein. In the largest specimen seen some of the secondaries, especially those of the median lobe are curved. Sinuses bordered by a marginal vein behind which is a curved secondary and inosculating tertiaries. The margins are entire and the texture is subcoriaceoous. |
