Phoenix dactylifera

Common name

date palm, edible date

Description

Stems: Clustering with age (unless suckering shoots are pruned), erect to 25 m tall and 45 cm in diameter, bulging with above ground roots at the base; leaf leaf:
in palms -- the leaf blade (which is usually divided into leaflets or leaf segments), the petiole (or leaf stalk) and the sheath (which forms the attachment of the leaf to the stem)
scars are spiraling, prominent raised knobs. In younger palms, the stem is covered with narrow, triangular leaf leaf:
in palms -- the leaf blade (which is usually divided into leaflets or leaf segments), the petiole (or leaf stalk) and the sheath (which forms the attachment of the leaf to the stem)
bases of fallen or pruned leaves. Leaves: Pinnate, induplicate,induplicate:
Most palm leaflets or leaf segments are obviously folded. If the folds create a V-shape, with the midrib lower than the margins (so that rain might fall "into a valley"), the folding is induplicate.
, to 6 m long, with a stiff rachis rachis:
an extension of the petiole through the blade of a pinnate leaf to which leaflets are attached
which ends in a single leaflet; many narrow, stiff, gray-green leaflets covered with a whitish bloom,bloom:
a white-gray waxy powder that covers a surface
, arranged in several planes; the lowermost leaflets (along the short petiole) are modified into sharp, thin spines; and no crown shaft crown shaft:
a cylinder of clasping leaf sheaths toward the apex of the stem, found in some pinnate-leaved palms (e.g., <em>Wodyetia bifurcata</em>)
is formed from leaf leaf:
in palms -- the leaf blade (which is usually divided into leaflets or leaf segments), the petiole (or leaf stalk) and the sheath (which forms the attachment of the leaf to the stem)
sheaths. Flowers and fruit: Inflorescences are orange-colored, 1-2 m long, and branched to one order. Creamy white staminate staminate:
a flower bearing stamens but no pistils; a “male” flower
and pistillate pistillate:
a flower bearing a pistil but no stamens; a “female” flower
flowers are produced on different plants. Fruits are up to 3-4 cm long, ovoid and yellow, red or orange-red when ripe.

Diagnostic features

Field: In younger palms, the stem is covered with narrow, triangular leaf leaf:
in palms -- the leaf blade (which is usually divided into leaflets or leaf segments), the petiole (or leaf stalk) and the sheath (which forms the attachment of the leaf to the stem)
bases of fallen or pruned leaves. With age, multiple stems are formed (unless suckering shoots are pruned); leaf leaf:
in palms -- the leaf blade (which is usually divided into leaflets or leaf segments), the petiole (or leaf stalk) and the sheath (which forms the attachment of the leaf to the stem)
scars spiraling, prominent raised knobs. Pinnate, induplicate induplicate:
Most palm leaflets or leaf segments are obviously folded. If the folds create a V-shape, with the midrib lower than the margins (so that rain might fall "into a valley"), the folding is induplicate.
leaves with spines formed from basal leaflets. Leaflets inserted in several planes.

May be confused with

Other Phoenix species, but the stem and leaflet arrangement are distinctive.

Distribution

Native to dry areas of Northern Africa and the Middle East

Additional comments

Because Phoenix species can hybridize easily and produce fertile crosses, determining the species within this genus might not be possible. Phoenix dactylifera has recently been used an ornamental landscape palm, in addition to its importance as a fruit crop.
