hyphaene thebaica
''Hyphaene thebaica'', with common names doum palm (Ar: دوم) and gingerbread tree (also doom palm), is a type of palm tree with edible oval fruit. It is a native to the Arabian Peninsula and also to the northern half of Africa〔(Kew World Checklist of Selected Plant Families )〕 where it is widely distributed and tends to grow in places where groundwater is present. It has been shown that dietary supplementation with doum palm extract has hypotensive and hypolipidemic effects.

The bark is fairly smooth, dark grey and bears the scars of fallen leaves. The petioles (leaf stalks) are about a metre long, sheathing the branch at the base and armed with stout upward-curving claws. The leaves are fan shaped and measure about . Male and female flowers are produced on separate trees. The inflorescences are similar in general appearance, up to about long, branching irregularly and with two or three spikes arising from each branchlet. Female trees produce large woody fruits, each containing a single seed, that remain on the tree for a long period.
