and distal marginal folds induplicate. Epidermal cells rectangular;
Plication with proximal and distal marginal folds induplicate. Epidermal
induplicate. Epidermal cells rectangular; adaxial and abaxial anticlinal
induplicate. Epidermal cells rectangular to slightly rhombohedral;
lobed at apex; induplicate folding; venation palmate or costapalmate
Plication proximal section not available; distal marginal folds, one margin reduplicate, the other margin induplicate. Epidermal cells rectangular, elongate; adaxial and abaxial anticlinal walls linear.
This character separates palms into two groups--palms with reduplicate (L-shaped) folding and palms with induplicate (V-shaped) folding.
These features are associated with almost constant features such as a single cataphyll, coleoptile present or absent, entire eophyll, reduced axis, parallel or palmate venation, induplicate plication, epidermal cells rectangular or sometimes rhombohedral, major veins associated or not associated with ridges, phloem strands 1-3, and metaxylem vessels 1-2.
The features associated with this type are two or more cataphylls, coleoptile present, segmented eophyll, distinct axis, pinnate or palmate venation, proximal plication induplicate, distal plication induplicate, epidermal cells rectangular, major veins associated with ridges, phloem strands 1-2, and metaxylem 1-2.
