=PALMÆ.=

814 =Phœnix dactylifera= _Linn._ NAKHLA—Arab. The Date Palm.

Cultivated, especially in the Northern parts of the Sudan, for its fruit, which is called BALAH or TAMR by Arabs.

The timber is used for beams and posts; mats, fans, baskets and ropes are made from the leaves and crates and baskets from the petioles. The tree yields a gum which is considered a useful remedy for diarrhœa. A perfume is obtained by distillation, from the spathes. Date sugar can be obtained from the juice tapped from the stem, but at the expense of the fruit crop. (Male DAKAR, female NITAYA, green date DUFFEIG or ROTAB, leave stalk GEREIDAH, spathe AF, male flowers ARGUN, female ZABATA, seed NAWA)—Arab.

Southern Sudan.

Almost every part of this palm is put to some use. The fibres from the leaves and leaf-stalks are used for rope making; the leaves for thatching; the pericarp of the fruit is edible, and the kernel itself is eaten when young. The wood is heavy, hard and durable, and is useful for building, canoes, water-pipes, etc. From the unopen spathes a sap is drawn which when fresh is sweet and when boiled down yields Date Sugar or Jaggery, it quickly ferments, and gives a raw spirit called toddy. The root tip as it emerges from the germinating seed is eaten as a vegetable.
