Definition of costapalmate

Categorized under "General"

Definition as written by palmbob:

This is a leaf (usually a palm leaf) that is partially palmate, and partially pinnate. Or some refer to it as an elongated palmate leaf. A costapalmate leaf has a definte costa (midrib) unlike the typical palmate leaf, but the leaflets are arranged radially like in a palmate leaf. All costapalmate leaves are markedly recurved, too, and oven have a \'V\' shape at the costa making them look very complex. Illustrating one has been a challenge and most illustrations of such a leaf are inaccurate and misleading. Most Sabal palms have costapalmate leaves. Many other species of Borassoid palms also have similarly shaped leaves. Some palms have only \'slightly\' costapalmate leaves, and are really palmate with a recognizable costa.
