description

Vegetative characteristics

Aloe compressa grows individually and is stemless or short-stemmed. The 15 to 20 triangular leaves are arranged in two rows and have a rounded tip. Your glauke leaf blade is 12 to 15 inches long and 5 inches wide. The leaf surface is smooth. The flattened, green or red-tipped teeth on the leaf margin are 2 millimeters long and 4 to 5 millimeters apart.

Inflorescences and flowers

The simple inflorescence , rarely a branch, reaches a length of 60 to 70 centimeters. The dense, almost egg-shaped grapes are 7 to 8 inches long and 6 inches wide. The long, pointed bracts, the upper ones are blunt and sanded, have a length of 20 to 24 millimeters and are 10 to 17 millimeters wide. They are white and have three brown veins. The white flowers have a red central stripe in the upper half and are on 1 to 2 millimeter long peduncles . The flowers are 25 to 33 millimeters long. Your outer tepals are not fused together. Their tips are clearly bent back. The stamens and the stylus do not protrude from the flower.

Systematics and distribution

Aloe compressa is common in Madagascar . Aloe compressa var. Compressa grows on quartzite rocks at altitudes from 1,000 to 1,500 meters. Aloe compressa var. Paucituberculata colonizes quartzite mountains at altitudes of 1725 to 1950 meters. Aloe compressa var. Rugosquamosa is common on quartzite rocks at altitudes of around 1350 meters. Aloe compressa var. Schistophila grows on slate rocks at altitudes of around 1000 meters.

The first description by Henri Perrier de La Bâthie was published in 1926.

A distinction is made between the following varieties :

  • Aloe compressa var. Compressa
  • Aloe compressa var. Paucituberculata Lavranos
  • Aloe compressa var. Rugosquamosa H.Perrier
  • Aloe compressa var. Schistophila H.Perrier

Aloe compressa var. Paucituberculata
The differences to Aloe compressa var. Compressa are: The leaves are 9 centimeters long and 4 centimeters wide and only sparsely warty.

The first description of the variety by John Jacob Lavranos was published in 1998.

Aloe compressa var. Rugosquamosa
In contrast to Aloe compressa var. Compressa , the grayish leaves are up to 23 centimeters long and 3 to 3.5 centimeters wide. The upper side of the leaf is rough and has tiny, blunt bumps. The teeth on the edge of the leaf are smaller and more crowded together. The inflorescence is stronger and often branched. The bracts are about 55 millimeters long and 15 millimeters wide. The flowers are 55 millimeters long.

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

Aloe compressa var. Schistophila
In contrast to Aloe compressa var. Compressa , the variety has more leaves that are more compressed and 12 centimeters long and 2 to 2.5 centimeters wide. The marginal teeth almost flow together. The inflorescence bears 4 centimeters long bunches. The 22 millimeter long flowers are reddish.

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