 Stem to 20 m tall and to 40 cm in diameter, solitary (Figs. 1-2) or apparently forking below ground and producing 2-4 stems of more or less the same size; leaves to 15; fruits extremely polymorphic in shape and size, to 12 cm long and 9 cm wide, orange-brown at maturity.

 Hyphaene compressa grows in coastal lowland regions and extends to inland areas along water courses, growing from see level to 1400 m. This species has been also reported growing in secondary vegetation.

 At least 32 different names are nowadays considered as synonyms of this extremely polymorphic species (e.g. Dransfield, 1986); most of these synonyms correspond to infraspecific taxa proposed by Beccari (1924) for a taxonomically complex H. multiformis.

 This species is endemic from East Africa. It was reported for Kenya and Tanzania and apparently extending north to Somalia and southwards to Mozambique (Dransfield, 2010). Hyphaene compressa may display some degree of hybridization with other species of Hyphaene present in its northern range of distribution.

 The leaves of this palm fulfill many subsistence and economic needs of the nomadic pastoralist and agro-pastoralist communities in the northern and eastern regions of Kenya (Amwatta, 2004).

 This is a highly polymorphic palm (Dransfield, 2010) that requires further taxonomic study.

The conservation status of this species has been recently assessed by Cosiaux et al. (2017) and the category of Least Concern (LC) has been proposed. You can get detailed information on this assessment by clicking in the following link: http://www.iucnredlist.org/details/95317478/0
