Description
Vegetative characteristics
Aloe marlothii growing stem -forming and easy. The upright stem reaches a length of up to 4 meters (rarely up to 6 meters ) and is covered with dead leaves. The 40 to 50 lanceolate narrowed leaves form dense rosettes. The dull gray -green to Glauce leaf blade is 100 to 150 inches long and 20 to 25 inches wide. On it are a few to many scattered, reddish brown, 3 to 4 millimeters long spines. On the underside of leaves they are more numerous. The pungent, reddish brown teeth on the leaf margin are 3-4 millimeters long and are 10 to 15 millimeters apart.
Inflorescences and flowers
The inflorescence consists of many branches and reaches a length of about 80 centimeters. The lower branches are branched again. The dense, horizontal to slightly oblique grapes consist of einseitswendigen flowers and are 30 to 50 inches long and 5-6 inches wide. In total there are 20 to 30 grapes available. The ovate to lanceolate - acute, brownish bracts have a length of about 8 to 9 mm and 5 mm wide. The orange to yellowish orange, clavate to bulbous flowers are at 5 mm long pedicles. The flowers are 30 to 35 millimeters long and rounded at their base. At the level of the ovary, the flowers to a diameter of about 7 millimeters. Furthermore, it has expanded and eventually narrowed to the mouth. Your outer tepals are not fused together over a length 20 to 23 millimeters. The stamens and the style protrude about 15 mm from the flower.

Systematics and distribution
Aloe marlothii is widespread in Mozambique, Botswana, South Africa and Swaziland.
The first description by Alwin Berger was published in 1905. The following taxa were included as a synonym in the way: (. . 1908, nom illeg ICBN article 53.1 ) Aloe ferox var xanthostachys A.Berger (1908, incorrect name ICBN article 11.4), Aloe ferox and Aloe A.Berger marlothii JM Wood (1912, nom. illeg. ICBN article 53.1 ).
We distinguish the following sub- types:
- Aloe marlothii subsp. marlothii
- Aloe marlothii subsp. orientalis Glen & D.S.Hardy
Aloe marlothii supsp. marlothii The subspecies is common in Botswana, Mozambique, the South African provinces of KwaZulu -Natal, Gauteng, Mpumalanga, Limpopo and North West and Swaziland on rocky hills at altitudes of 1000-1800 meters. The following taxa were included as a synonym in the subspecies: Aloe var supraleavis hanburyi Baker ( 1896), Aloe spectabilis Reynolds (1927) and Aloe marlothii bicolor var Reynolds ( 1936).
Ronell Klopper Renett and Gideon Francois Smith recognized, 2010 Aloe spectabilis again.
Aloe marlothii subsp. orientalis The differences with Aloe marlothii subsp. marlothii are: the variety budded and often forms lumps. Your upright or prostrate to crooked stems are up to 1.75 meters long. At the leaf surface are few or no prickles. The flower clusters on the inflorescence are wrong.
The first description of the subspecies by Hugh Francis and Glen David Spencer Hardy was released in 1987. Aloe marlothii subsp. orientalis is widespread in the extreme south of Mozambique, in the South African province of KwaZulu -Natal and in Swaziland on sandy soils at altitudes of 15 to 500 meters.
