description
Vegetative characteristics
Aloe lineata grows trunk-forming, is solitary or branched. The simple trunk is up to 1.5 meters long and is usually covered with dead leaves. The 30 to 40, lanceolate, pointed leaves form a dense rosette . The cloudy to bright green, clearly lined leaf blade is 30 to 40 centimeters long and 7 to 9 centimeters wide. The piercing, reddish brown teeth on the reddish brown leaf margin are 4 to 6 millimeters long and 5 to 15 millimeters apart.
Inflorescences and flowers
The simple inflorescence reaches a length of 75 to 100 centimeters. The rather dense, conical grapes are 20 to 30 centimeters long. The deltoid-pointed bracts have a length of about 20 millimeters. The salmon pink flowers are on 40 millimeter long peduncles . The flowers are 45 to 50 millimeters long and truncated at their base. At the level of the ovary , they have a diameter of 9 millimeters. Above it, they are narrowed to 8 millimeters, then expanded to 11 millimeters and finally narrowed slightly towards the mouth. Your outer tepals are almost not fused together. The stamens and the style stick out slightly from the flower. The flowering period extends from February to March.

Systematics and distribution
Aloe lineata is common in South Africa. Aloe lineata var. Lineata grows in the provinces of Western Cape and Eastern Cape in dry bush and on grasslands from sea level to altitudes of 1400 meters. Aloe lineata var. Muirii is common on quartzite slopes in the Western Cape Province.
The first description as Aloe perfoliata var. Lineata was published in 1789 by William Aiton . Haworth raised the variety to the rank of a kind in 1804. The following varieties are distinguished:
- Aloe lineata var. Lineata
- Aloe lineata var. Muirii (Marl.) Reynolds
Aloe lineata var. Lineata
synonyms are Aloe lineata var. Glaucescens Haw. (1821) and Aloe lineata var. Viridis Haw. (1821).
Aloe lineata var. Muirii
The variety differs from Aloe lineata var. Lineata by the larger leaf margin teeth and the bright yellowish green to slightly orange-red leaves, which are more clearly reddish-lined. The flowering time usually extends from July to September.
The first description as Aloe muirii by Rudolf Marloth was published in 1929. Gilbert Westacott Reynolds introduced the species in 1950 as a variety to Aloe lineata .
