description

Vegetative characteristics

Aloe marlothii grows easily and in a stem-forming manner. The upright trunk 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 cloudy gray-green to blue leaf blade is 100 to 150 centimeters long and 20 to 25 centimeters wide. There are a few to many scattered, reddish-brown, 3 to 4 millimeter long spines on it. They are more numerous on the underside of the leaf. The piercing, reddish-brown teeth on the leaf margin are 3 to 4 millimeters long and 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 crooked grapes consist of single-sided flowers and are 30 to 50 centimeters long and 5 to 6 centimeters wide. There are a total of 20 to 30 grapes. The egg-shaped to lanceolate-pointed, brownish bracts have a length of about 8 to 9 millimeters and are 5 millimeters wide. The orange to yellowish orange, club-shaped to bulbous flowers are on 5 millimeter long peduncles . The flowers are 30 to 35 millimeters long and rounded at their base. At the level of the ovary , the flowers have a diameter of about 7 millimeters. Above it they are expanded and finally narrowed to the mouth. Your outer tepals are not fused together over a length of 20 to 23 millimeters. The stamens and the style stick out about 15 millimeters from the flower.

Systematics and distribution

Aloe marlothii is common 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 species: Aloe ferox var. Xanthostachys A.Berger (1908, incorrect name ICBN -Article 11.4), Aloe ferox A.Berger (1908, nom. Illeg. ICBN -Article 53.1) and Aloe marlothii JM Wood (1912, nom. Illeg. ICBN -Article 53.1).

The following subspecies are distinguished:

Aloe marlothii subsp. marlothii
Aloe marlothii subsp. orientalis Glen & DSHardy

Aloe marlothii supsp. marlothii
The subspecies is distributed in Botswana, Mozambique, the South African provinces of KwaZulu-Natal , Gauteng , Mpumalanga , Limpopo and Northwest as well as Swaziland on rocky hills at altitudes of 1000 to 1800 meters. The following taxa were included as synonymous in the subspecies: Aloe supraleavis var. Hanburyi Baker (1896), Aloe spectabilis Reynolds (1927) and Aloe marlothii var. Bicolor Reynolds (1936).

Ronell Renett Klopper and Gideon Francois Smith recognized Aloe spectabilis again in 2010 .

Aloe marlothii subsp. orientalis
The differences to Aloe marlothii subsp. marlothii are: The variety often sprouts and forms clumps. Their upright or prostrate to crooked trunks are up to 1.75 meters long. There are few or no spines on the leaf surface. The flower clusters on the inflorescence are crooked.

The first description of the subspecies by Hugh Francis Glen and David Spencer Hardy was published in 1987. Aloe marlothii subsp. orientalis is distributed in the extreme south of Mozambique, in the South African province of KwaZulu-Natal and in Swaziland on sandy soil at heights of 15 to 500 meters.
