description

Vegetative characteristics

Aloe capitata usually grows singly and without a trunk or in the shade with a trunk of up to 60 centimeters in length. The 20 to 30 triangular, pointed leaves form dense rosettes . The tip of the leaf is slightly twisted, blunt and toothed short. The green, reddish tinged leaf blade is 50 centimeters long and 6 centimeters wide. The stinging, reddish teeth on the brownish red, cartilaginous leaf margin are 2 millimeters long and 8 to 12 millimeters apart. The leaf sap is dry yellow.

Inflorescences and flowers

The inflorescence consists of three to four branches and reaches a length of about 80 centimeters. The close-headed grapes are 3 to 4 inches long and 9 to 10 inches wide. The egg-shaped-pointed bracts have a length of 6 millimeters and are 4 millimeters wide. The lowest flower stalks are 10 millimeters long, further up they reach a length of 25 to 30 millimeters. The narrow, bell-shaped, orange-yellow flowers are 25 to 30 millimeters long and rounded at their base. At the level of the ovary , they have a diameter of 6 millimeters. Above this, the flowers are expanded to 10 millimeters towards the mouth. Your outer tepals are not fused together, but stick together over a length of 24 to 25 millimeters. The stamens and the style stick out 10 millimeters from the flower.

Systematics and distribution

Aloe capitata is common in Madagascar .

The first description by John Gilbert Baker was published in 1883. A distinction is made between the following varieties :

  • Aloe capitata var. Capitata
  • Aloe capitata var. Angavoana J.-P. Castillon
  • Aloe capitata var. Cipolinicola H.Perrier
  • Aloe capitata var. Gneissicola H.Perrier
  • Aloe capitata var. Quartziticola H.Perrier
  • Aloe capitata var. Silvicola H.Perrier

Aloe capitata var. Capitata
A synonym of Aloe capitata var. Capitata is Aloe cernua death. (1890).

Aloe capitata var. Angavoana
The first description of the variety was made by Jean-Philippe Castillon and was published in 2010.

Aloe capitata var. Cipolinicola
The differences to Aloe capitata var. Capitata are: The variety grows individually and forms a trunk with a trunk 2 to 3 meters long. The 60 to 100 leaves form dense rosettes. There are two to three small teeth on the pointed tip of the leaf. The shiny green, occasionally tinged reddish leaf blade is 60 centimeters long and 5 to 6.5 centimeters wide. The peripheral teeth are 3 to 4 millimeters long. The inflorescence becomes about 1 meter long and consists of six to ten branches. The lowest flower stalks are almost missing.

The first description of the variety by Henri Perrier de La Bâthie was published in 1926. A nomenclatory synonym is Aloe cipolinicola (H.Perrier) J.-B.Castillon & J.-P.Castillon (2010).

Aloe capitata var. Gneissicola
The differences to Aloe capitata var. Capitata are: The variety has about 20 lanceolate leaves that are rounded at the tip and have three to five teeth there. The gray-green to blue leaf blade is 40 to 50 centimeters long and 3.5 to 4 centimeters wide. The flower clusters consist of fewer individual flowers that are 35 millimeters long. The fragile bracts are 10 millimeters long and 5 millimeters wide. The lowest flower stalk is 5 millimeters, the top 35 millimeters long.

The first description of the variety was also made by Henri Perrier de La Bâthie and was published in 1926. A nomenclature synonym is Aloe gneissicola (H.Perrier) J.-B.Castillon & J.-P.Castillon (2010).

Aloe capitata var. Quartziticola
The differences to Aloe capitata var. Capitata are: The leaves are thick and fleshy. The glauke to bluish green leaf blade is 30 to 40 centimeters long and 9 to 12 centimeters wide. The 3 to 4 millimeter long peripheral teeth are 10 to 20 millimeters apart. The inflorescence reaches a length of 1 meter. The rather dense, 10 to 12 centimeter long flower clusters consist of more individual flowers. The narrow-deltoid bracts are 7 to 10 millimeters long and 3 to 4 millimeters wide. The lowest flower stalks are 15 to 20 millimeters, the top 40 to 50 millimeters long.

The first description of the variety was also made by Henri Perrier de La Bâthie and was published in 1926.

Aloe capitata var. Silvicola
The differences to Aloe capitata var. Capitata are: The variety grows with a short trunk, lying on tree trunks or rocks. The leaf blade is 50 to 60 inches long and 3 to 4 inches wide. The teeth on the leaf margin are very small and occasionally missing. The bracts rounded towards the tips are 7 millimeters long and 6 millimeters wide. The flowers are 20 millimeters long. The lowest flower stalks are 8 millimeters, the top up to 40 millimeters long.

The first description of the variety was also made by Henri Perrier de La Bâthie and was published in 1926.
