Original diagnosis/description

Leaves large, simple; elongate-lanceolate, entire-margined. Apex and base unknown. Venation eucamptodromous, parallel-pinnate. Midrib costa massive, deeply impressed, probably reaching the apex, consisting of numerous vascular bundles. Laterals emerging at low angle from midrib. Parallel venation consisting of three weekly differentiated vein subsets arranged according to the formula BdCdB. Transverse vein sets of two categories, connecting adjacent parallel veins or veins of the same subset (C–C, d–d) being oriented obliquely or perpendicularly. Areoles polygonal-quadrangular, elongate.

Emended diagnosis

Bogner et al. (2007: Zitteliana, Ser. A, 47: 142):
Corrected addition to the description: Leaf blade with only primary lateral veins pinnate, higher-order venation ± regularly transverse reticulate between them.

Kvaček, J. and Smith (2015: Bot. J. Linn. Soc., 178(3): 492):
Leaf entire-margined, midrib multistranded, venation parallel-pinnate, eucamptodromous. Primary lateral venation consisting of three well-defined vein subsets leaving costa at low angles. Higher order transverse venation perpendicular to slightly oblique, reticulate. Transverse veins irregularly connecting all orders of primary lateral veins.
