Description
Borassoid palms typically have large, column-like trunks, though several species of Hyphaene have branching or clustered stems. The leaves are large, palmate and often with spines or sharp edges along the petioles. Leaves are retained on young palm stems, later falling to reveal prominent scars. All genera in the Borasseae are , with separate male and female trees; they are pleonanthic, flowering regularly for many years. are large and pendulous; the male flowers are much smaller than the female and are borne in clusters within catkin-like structures. Fruits contain hard, woody surrounding the seeds; they range in size from -sized ( ) to the massive fruits of , which contain the largest seed in the world.

Taxonomy
The Borasseae is one of eight tribes in subfamily Coryphoideae. The tribe is and most studies place it as sister to tribe , though it is also close to tribe and tribe . Together, the four tribes make up the clade, all members of which have syncarpous ovaries with united .

The eight genera of tribe Borasseae split evenly into two subtribes. In the palms of subtribe , both the male and female flowers are sunken within pits and the fruits are stalked and typically one-seeded. (1 sp., B. nobilis) and (1 sp., S. decussilvae) are to Madagascar, (1 sp., M. argun) is restricted to and , while Hyphaene (8 spp.) ranges from southern Africa and Madagascar to western India. In subtribe , only the male flowers are sunken in pits and the fruits are sessile, with 1-3 seeds. (1 sp., L. maldivica) is endemic to the , (3 spp.) is endemic to the Mascarene Islands, while has two species, one in ( B. borneense) and one in the ( B. machadonis). The last of the genera, (5 spp.), is the most widespread and is found in Sub-Saharan Africa, Madagascar, and New Guinea. An extinct genus of the subtribe Hyphaeninae is known from the aged of India.
