Calamus is a genus of flowering plants in the palm family Arecaceae that are among several genera known as rattan palms. There are an estimated 400 species in this genus, all native to tropical and subtropical Asia, Africa, and Australia. They are mostly leaf-climbing lianas with slender, reedy stems. To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified "pinnae" or tendrils in the form of stout, backward-pointing spines. These stems may grow to lengths of 200 metres.
Bactris is a genus of spiny palms which is native to the Mexico, South and Central America and the Caribbean.

Saribus brevifolius is a species of palm tree in the genus Saribus, which has only been found in the Kawe and Gag Islands in the archipelago of the Raja Ampat Islands, which lie off the north-west tip of the Bird's Head Peninsula in Indonesia's West Papua province. It was only discovered in 2002 during an expedition funded by The Nature Conservancy. The palm grows along the coasts of these two tropical islands on small ridges composed of ultrabasic rock. It is a moderately-sized fan palm with smallish and regularly segmented leaves and a smallish inflorescence in the crown. The inflorescence is not longer than the leaves, and split at its base into three main branches with one or more sub-inflorescences, these containing red flowers with pink anthers. The ends of S. brevifolius leaf segments are rigid and have a bifurcate cleft 1-4% of the segment length.
Jailoloa is a genus of palm, in the subtribe Ptychospermatinae. It has only one currently accepted species, Jailoloa halmaherensis, native to the Moluccas. It only grows on ultramafic soils.
