Description
Vegetative characteristics
Aloe arborescens growing stem -forming and strong branching. The strain reaches a length of 2 to 3 meters and is at the base up to 30 inches thick. It is covered over a length of 30 to 60 centimeters with persistent dead leaves. The triangular leaves form a tight rosette. The dull green to gray-green leaf blade is 50 to 60 inches long and 5-7 inches wide. The fixed teeth on the leaf margin are 3-5 millimeters long and are 5 to 20 mm apart. They are usually bent in the direction of Blatzspitze.
Inflorescences and flowers
The usually simple inflorescence has occasionally on a branch, and is 60 to 80 inches long. The dense, conical to conical extended grapes are 20 to 30 inches long and 10 to 12 inches wide. The ovate - acute to obtuse bracts have a length of 15 to 20 mm and are 10 to 12 millimeters wide. The scarlet flowers are at 35 to 40 mm long pedicles. The flowers are 40 mm long and rounded at their base. At the level of the ovary, they have a diameter of 7 millimeters. In addition they are slightly narrowed and eventually extended to the mouth. Your outer tepals are not fused together. The stamens and the style protrude approximately 5 mm from the flower.

Systematics and distribution
Aloe arborescens is widespread in Malawi, Mozambique, Zimbabwe and South Africa from sea level up to altitudes of 2800 meters. It typically grows on rocky slopes and is occasionally found in the dense bush.
The first description by Philip Miller was published in 1768.
The following taxa were included as a synonym in the nature: Aloe perfoliata var η L. (1753 ), Aloe fruticosa Lam. (1783 ), Aloe arborea Medik. (1783, nom. Illeg. ICBN article 53.1 ), Aloe perfoliata var arborescens Aiton (1789 ), Catevala arborescens Medik. (1789 ), Aloe frutescens Salm- Dyck (1817 ), Aloe arborescens var frutescens ( Salm- Dyck ) Link (1821 ), Aloe natalensis JMWood & MSEvans (1901 ), Aloe arborescens var natalensis ( JMWood & MSEvans ) A.Berger (1908), Aloe arborescens var milleri A.Berger (1908), Aloe arborescens var pachythyrsa A.Berger (1908 ).
We distinguish the following sub- types:
- Aloe arborescens subsp. arborescens
- Aloe arborescens subsp. mzimnyati van Jaarsv. & A.E.van Wyk
Aloe arborescens subsp. mzimnyati Aloe arborescens subsp. mzimnyati is smaller in the entire habitus. The leaves are 12 to 21 inches long and from 0.8 to 1 centimeters wide. The slightly club-shaped flowers have a length of 22 to 25 millimeters. Their color varies from orange-red to orange to various shades of yellow.
The first description of this subspecies by Ernst Jacobus van Jaarsveld and Abraham Erasmus van Wyk was published in 2005. It is on the river Mzimnyati used in the South African province of KwaZulu -Natal, northeast of Krantzkop mainly quartzitic sandstone cliffs at altitudes of about 500 meters and is only in the area of the type locality known.
