Fan palm
The fan palm is the name given to palm species that have palmate leaves that are cut in the shape of a hand . The outline of the leaf is fan-shaped, the leaf veins radiate from the base of the petiole to the leaf margin. Often here also is on Spreitengrund Hastula trained. The contrast Fiederpalmen , the feathered (pinnate) leaves possess as date palms and oil palms .
Palmate leaves in the strict sense are rather rare, an example being the genus Thrinax . Much more common are costapalmate, i.e. leaves that are split in the shape of a hand and have a clearly pronounced midrib (costa) that extends far into the leaf blade.
Most palms have more or less severely divided leaves. Some species of the genus Licuala and all representatives of Johannesteijsmannia have undivided leaves .
Palms with palmate leaves are clearly in the minority compared to those with pinnate (pinnate) leaves. Palmate leaves have the following groups:
- The following tribes of the Coryphoideae : Sabaleae , Cryosophileae , Trachycarpeae , Chuniophoeniceae , Corypheae , Borasseae
- Mauritiinae within the Calamoideae
