Distribution area

Aloe ciliaris is a plant genus Aloe ( Aloe ) in the subfamily of asphodeloideae (Asphodeloideae). The specific epithet ciliaris comes from the Latin , means 'ciliate' and refers to the ciliate leaf sheaths of the species. Its three varieties differ in their degree of ploidy .

description

Vegetative characteristics

Aloe ciliaris grows trunk-forming, branched and is spreading . The trunk reaches a length of up to 5 meters or more and is 1 to 1.5 centimeters thick. The linear-lanceolate, long, pointed leaves are scattered along the trunks over a length of 30 to 60 centimeters. Their green leaf blades are 10 to 15 inches long and 1.5 to 2.5 inches wide. The firm, white teeth on the edge of the leaf are 1 millimeter long and 3 millimeters apart. The marginal teeth become shorter towards the tip of the leaf. The indistinct green lined leaf sheath is 5 to 15 millimeters long. At the upper edge opposite the leaf blade there is a border of 2 to 4 millimeters long eyelashes.

Inflorescences and flowers

The usually simple inflorescence sometimes has a branch and is 20 to 30 centimeters long. The rather dense, conical grapes are 8 to 15 inches long and 4 to 5 inches wide. They consist of 24 to 30 flowers. The egg-shaped pointed bracts have a length of 4 to 5 millimeters. The scarlet flowers are yellowish green at their mouth and stand on approximately 5 millimeter long peduncles . The slightly club-shaped flowers are 28 to 35 millimeters long and very short at their base. Above the ovary , the flowers are gradually expanded. Your outer tepals are not fused together over a length of 6 millimeters. The stamens and the pen stand 2 to 4 millimeters out from the flower.

genetics

The number of chromosomes is , i. H. the variety is hexaploid. ${\displaystyle 2n=42}$

Systematics and distribution

Aloe ciliaris is common in the South African province of Eastern Cape . Aloe ciliaris var. Ciliaris grows between bushes and trees and is supported by them. Aloe ciliaris var. Redacta grows on sand dunes and Aloe ciliaris var. Tidmarshii on temperate mountain slopes.

The first description by Adrian Hardy Haworth was published in 1825. A nomenclature synonym is Aloiampelos ciliaris (Haw.) Klopper & Gideon F.Sm. (2013).

A distinction is made between the following varieties :

• Aloe ciliaris var. Ciliaris
• Aloe ciliaris var. Redacta S. Carter
• Aloe ciliaris var. Tidmarshii Schönland

Aloe ciliaris var. Ciliaris
synonyms are Aloe ciliaris var. Flanaganii Schönland (1903), Aloe ciliaris f. flanaganii (Schönland) Resende (1943) and Aloe ciliaris f. gigas Resende (1938).

Aloe ciliaris var. Redacta
The variety differs from Aloe ciliaris var. Ciliaris by the 1 to 2 millimeter long eyelashes on the leaf sheaths, the 4 to 5 millimeter long bracts, the 12 to 14 millimeter long flower stalks and the 21 to 25 millimeter long flowers . The variety is tetraploid (). ${\displaystyle 2n=42}$

The first description of the variety by Susan Carter was published in 1990. A synonym is Aloiampelos ciliaris var. Redacta (S.Carter) Klopper & Gideon F.Sm. (2013).

Aloe ciliaris var. Tidmarshii
The differences to Aloe ciliaris var. Ciliaris are: The leaves are only 7 to 10 centimeters long and only 1.5 to 2 centimeters wide. The eyelashes on the leaf sheaths are shorter than 1 millimeter. The flower clusters are somewhat looser and the flowers 16 to 25 millimeters long. The variety is diploid (). ${\displaystyle 2n=14}$

The first description of the variety by Selmar Schönland was published in 1903. Synonyms are Aloe ciliaris f. tidmarshii (Schönland) Resende (1943), Aloe tidmarshii (Schönland) FSMüller ex RADyer (1943) and Aloiampelos ciliaris var. tidmarshii (Schönland) Klopper & Gideon F.Sm. (2013).
