Algeria comprises 2,381,741 square kilometers of land, more than four-fifths of which is desert, in northern Africa, between Morocco and Tunisia. It is the largest country in Africa. Its Arabic name, Al Jazair, derives from the name of the capital Algiers, after the small islands formerly found in its harbor. It has a long Mediterranean coastline. The northern portion, an area of mountains, valleys, and plateaus between the Mediterranean Sea and the Sahara Desert, forms an integral part of the section of North Africa known as the Maghreb. This area includes Morocco, Tunisia, and Libya.
The Atlas Mountains are a mountain range in the Maghreb. It separates the Mediterranean and Atlantic coastlines from the Sahara Desert. It stretches around 2,500 km (1,600 mi) through Morocco, Algeria and Tunisia. The range's highest peak is Toubkal, which is in central Morocco, with an elevation of 4,167 metres (13,671 ft). The Atlas mountains are primarily inhabited by Berber populations. The terms for 'mountain' are adrar and adras in some Berber languages. These terms are believed to be cognates of the toponym Atlas. The mountains are also home to a number of animals and plants which are mostly found within Africa but some of which can be found in Europe. Many of these species are endangered and a few are already extinct.
Erysimum, or wallflower, is a genus of flowering plants in the cabbage family, Brassicaceae. It includes more than 150 species, both popular garden plants and many wild forms. The genus Cheiranthus is sometimes included here in whole or in part. Erysimum has since the early 21st century been ascribed to a monogeneric cruciferous tribe, Erysimeae, characterised by sessile, stellate (star-shaped) and/or malpighiaceous (two-sided) trichomes, yellow to orange flowers and multiseeded siliques.

The Saharan Atlas is a range of the Atlas Mountain System. It is located mainly in Algeria, with its eastern end in Tunisia. Although not as tall as the High Atlas of Morocco its summits are more imposing than the Tell Atlas range that runs parallel closer to the coast.

The Tell Atlas is a mountain chain over 1,500 km (932 mi) in length, belonging to the Atlas mountain ranges in North Africa, stretching mainly across northern Algeria, with ends in both north-eastern Morocco and north-western Tunisia.
The Middle Atlas is a mountain range in Morocco. It is part of the Atlas mountain range, a mountainous region with more than 100,000 km2, 15 percent of its landmass, rising above 2,000 metres. The Middle Atlas is the northernmost and second highest of three main Atlas Mountains chains of Morocco. To south, separated by the Moulouya and Um Er-Rbiâ rivers, lies the High Atlas. The Middle Atlas form the westernmost end of a large plateaued basin extending eastward into Algeria, also bounded by the Tell Atlas to the north and the Saharan Atlas to the south, both lying largely in Algeria. North of the Middle Atlas and separated by the Sebou River, lie the Rif mountains which are an extension of the Baetic System, which includes the Sierra Nevada in the south of Spain. The basin of the Sebou is not only the primary transportation route between Atlantic Morocco and Mediterranean Morocco but is an area, watered by the Middle Atlas range, that constitutes the principal agricultural region of the country.
Erysimum nevadense is a perennial short-lived herb endemic to the Sierra Nevada of Spain, although there are some citations in the nearby Sierra de Gádor (Almería). This wallflower occurs between 1,700–2,700 m above sea level in subalpine scrublands and alpine meadows. This species belongs to the nevadense complex species, together with five more Iberian species.
