Aloe, also written Aloë, is a genus containing over 550 species of flowering succulent plants. The most widely known species is Aloe vera, or "true aloe". It is called this because it is cultivated as the standard source for assorted pharmaceutical purposes. Other species, such as Aloe ferox, are also cultivated or harvested from the wild for similar applications.
A shrub is a small- to medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than 6–10 m (20–33 ft) tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed subshrubs.
The Central American river turtle, also known locally as the hickatee or tortuga blanca, is the only living species in the family Dermatemydidae. Its closest relatives are only known from fossils with some 19 genera described from a worldwide distribution from the Jurassic and Cretaceous. The species is currently found in the Atlantic drainages of Central America, specifically southern Mexico, Belize and Guatemala. It is a relatively large-bodied species, with historical records of 60 cm (24 in) stright carapace length and weights of 22 kg (49 lb); however, more recent records have found few individuals over 14 kg (31 lb) in Mexico or 11 kg (24 lb) in Guatemala.
Aloe vera is a succulent plant species of the genus Aloe. Having some 500 species, Aloe is widely distributed, and is considered an invasive species in many world regions.
Aloidendron barberae, formerly Aloe bainesii and Aloe barberae, also known as the tree aloe, is a species of succulent plant in the genus Aloidendron. It is native to South Africa northwards to Mozambique. In its native climes this slow-growing tree can reach up to 60 feet (18 m) high and 36 inches (0.91 m) in stem diameter. Aloidendron barberae is Africa's largest aloe-like plant. The tree aloe is often used as an ornamental plant. Its tubular flowers are rose pink (green-tipped); it flowers in winter and in its natural environment is pollinated by sunbirds.
Aloe marlothii is a large, single-stemmed Southern African aloe of rocky places and open flat country, occasionally growing up to 6m tall.
Aloe ferox, commonly known as bitter aloe, is a species of flowering plant in the family Asphodelaceae. This woody aloe is indigenous to southern Africa. It is one of several Aloe species used to make bitter aloes, a purgative medication, and also yields a non-bitter gel that can be used in cosmetics.
Aloiampelos striatula, formerly Aloe striatula, the hardy aloe or striped-stemmed aloe, is a sturdy succulent plant that naturally occurs on the summits of mountains along the south of the Karoo region of South Africa. Tough and hardy, with bright yellow flowers, it is also cultivated as a garden ornamental.
Aloiampelos ciliaris, formerly Aloe ciliaris, the common climbing-aloe, is a thin, tough, rapidly growing succulent plant from South Africa.
Aloiampelos tenuior, formerly Aloe tenuior, the fence aloe, is a bushy, multi-branched succulent plant from the grasslands and thickets of the Eastern Cape, Kwazulu Natal and Mpumalanga, South Africa. Its preferred habitat is sandy soils in open country, unlike many of its relatives that favour thicket vegetation. It is one of the most profusely flowering of all aloes and their relatives.
Aloiampelos gracilis, formerly Aloe gracilis, the rocket aloe, is a succulent plant, endemic to dry thicket vegetation around the city of Port Elizabeth, South Africa. Its natural range lies just to the west of the related Aloiampelos ciliaris, and it occurs in bushy fynbos and dry thickets, and clustered on rocky outcrops at all altitudes. Its range extends westwards into the Baviaanskloof mountains.
Aloe perfoliata, the rubble aloe or mitre aloe, is a hardy creeping aloe, found in rocky, mountainous areas throughout the Western Cape, South Africa.
Aloiampelos, formerly Aloe ser. Macrifoliae is a genus of succulent plants in the subfamily Asphodeloideae, comprising seven species found in Southern Africa. They are typically multi-branched climbing or sprawling shrubs, with long spindly stems and a large woody base on the ground. These characteristics, as well as their soft, narrow, triangular leaves whose lower part ensheathes the stem, make them easy to distinguish.
Aloe arenicola is a spotted creeping aloe, indigenous to the arid west coast of South Africa.
Aloe pluridens is an arborescent aloe indigenous to southern Africa.
Aloe purpurea is a species of Aloe endemic to the island of Mauritius, in the Indian Ocean, where it formerly occurred on dry rocky slopes and outcrops, the highland plateaus, and the forests of the west. It is part of a group of aloes which bear fleshy berries, and were therefore classed as a separate group, "Lomatophyllum". It is also one of only two Aloe species which naturally occur on Mauritius - both endemic and occurring nowhere else.
Aloe macra is a species of Aloe endemic to the island of Réunion, in the Indian Ocean.
Aloe babatiensis is an aloe which occurs at higher altitudes in northern Tanzania.
Aloe volkensii is a species of plant widely distributed in East Africa.
