Palm tree in the context of "Tamar (name)"

A river island is any exposed landmass surrounded by river water. Properly defined, it excludes shoals between seasonally varying flows and may exclude semi-coastal islands in river deltas such as Marajó.

These islands result from changes in the course of a river. Such changes may be caused by interactions with a tributary, or by the opposing fluvial actions of deposition and/or erosion that form a natural cut and meander. Nascent vegetation-free shoals and mudflats may dissipate and shift or build up into such islands through deposition; the process may be assisted through artificial reinforcement or natural factors, such as reeds, palms, evergreen trees or willows, that act as obstacles or erosion barriers, so that water flows around them. Islands may be small or large, covering many square kilometers, examples of which are given below.

The Tibesti Mountains are a mountain range in the central Sahara, primarily located in the extreme north of Chad, with a small portion located in southern Libya. The highest peak in the range, Emi Koussi, lies to the south at a height of 3,415 meters (11,204 ft) and is the highest point in both Chad and the Sahara. Bikku Bitti, the highest peak in Libya, is located in the north of the range. The central third of the Tibesti is of volcanic origin and consists of five volcanoes topped by large depressions: Emi Koussi, Tarso Toon, Tarso Voon, Tarso Yega and Toussidé. Major lava flows have formed vast plateaus that overlie Paleozoic sandstone. The volcanic activity was the result of a continental hotspot that arose during the Oligocene and continued in some places until the Holocene, creating fumaroles, hot springs, mud pools and deposits of natron and sulfur. Erosion has shaped volcanic spires and carved an extensive network of canyons through which run rivers subject to highly irregular flows that are rapidly lost to the desert sands.

Tibesti, which means "place where the mountain people live", is the domain of the Toubou people. The Toubou live mainly along the wadis, on rare oases where palm trees and limited grains grow. They harness the water that collects in gueltas, the supply of which is highly variable from year-to-year and decade-to-decade. The plateaus are used to graze livestock in the winter and harvest grain in the summer. Temperatures are high, although the altitude ensures that the range is cooler than the surrounding desert. The Toubou, who were settled in the range by the 5th century BC, adapted to these conditions and turned the range into a large natural fortress. They arrived in several waves, taking refuge in times of conflict and dispersing in times of prosperity, although not without intense internal hostility at times.

The palmette is a motif in decorative art which, in its most characteristic expression, resembles the fan-shaped leaves of a palm tree, like palmyra leaf. It has a far-reaching history, originating in ancient Egypt with a subsequent development through the art of most of Eurasia, often in forms that bear relatively little resemblance to the original. In ancient Greek and Roman uses it is also known as the anthemion (from the Greek ανθέμιον, a flower). It is found in most artistic media, but especially as an architectural ornament, whether carved or painted, and painted on ceramics. It is very often a component of the design of a frieze or border. The complex evolution of the palmette was first traced by Alois Riegl in his Stilfragen of 1893. The half-palmette, bisected vertically, is also a very common motif, found in many mutated and vestigial forms, and especially important in the development of plant-based scroll ornament.

Hadass (Hebrew: הדס‎, pl. hadassim - הדסים‎) is a branch of the myrtle tree that forms part of the netilat loulav used on the Jewish holiday of Sukkot.

Hadass is one of the four species (arbaʿath haminim – ארבעת המינים‎). The others are the lulav (date palm frond), aravah (willow), and etrog (citron). Three hadassim are incorporated into the Four Species and are bound together with the lulav and aravah. Together with the etrog, the lulav is waved in all four directions, plus up and down, to attest to God's mastery over all creation, and to voice a prayer for adequate rainfall over all the Earth's vegetation in the coming year.

Hyphaene thebaica, with common names doum palm (Ar: دوم) and gingerbread tree (also mistakenly 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 and western part of Africa where it is widely distributed and tends to grow in places where groundwater is present.

A naboot (nabboot, asaya, asa, shoum) is a Fighting stick constructed of palm wood or rattan. It originated in Egypt and is used in the martial art of Tahtib still practiced today in upper Egypt.In Egypt the Naboot was the main weapon of the Futuwwa , in 1906 a law was passed in Egypt banning the use of Naboots in fights, the law aimed to strip the Futuwwas of their power
