description
Vegetative characteristics
Aloe menyharthii grows without a stem or with a very short stem, is solitary or forms small groups of three to four rosettes . The lanceolate, narrowed leaves form a dense rosette of leaves . The leaf blade is 25 to 40 inches long and 6 to 9 inches wide. Your top two to four inches will soon dry up. On the dark green upper side of the leaf there are elongated to confluent H-shaped spots that form irregular transverse bands. The underside is lighter green, indistinctly lined and usually not spotted. The piercing, reddish-brown teeth on the leaf margin are 4 millimeters long and are less than 1 millimeter apart.
Inflorescences and flowers
The inflorescence has eight to twelve branches and reaches a length of 150 to 175 centimeters. The lower branches are occasionally branched again. The dense, head-on-the-face grapes are 6 to 8 inches long and 7 to 8 inches wide. The lanceolate bracts have a length of about 10 to 12 millimeters. The coral-red to pinkish-scarlet flowers are on 20 to 25 millimeter long peduncles . The flowers are 25 to 30 millimeters long. At the level of the ovary , they have a diameter of about 9 millimeters. Above this they are abruptly narrowed and gradually widened towards the mouth. Your tepals are not fused together over a length of about 8 millimeters. The stamens and the stylus barely protrude from the flower.
Systematics and distribution
Aloe menyharthii is common in Malawi and Mozambique . Aloe menyharthii subsp. menyhartii grows in the south of Malawi and in neighboring Mozambique on grasslands in open bush and brachystegia forests at heights of 300 to 1500 meters. Aloe menyharthii subsp. ensifolia is widespread in Mozambique in grasslands on sandy soils in open Brachystegia woodlands at heights of 130 to 700 meters.
The first description by John Gilbert Baker was published in 1898. The following subspecies are distinguished:
- Aloe menyharthii subsp. menyhartii
- Aloe menyharthii subsp. ensifolia S. Carter
Aloe menyharthii subsp. ensifolia
Aloe menyharthii subsp. ensifolia differs from Aloe menyharthii subsp. menyhartii by the lanceolate, 40 to 70 centimeters long and 3 to 5.5 centimeters wide leaves. Your tip does not dry out prematurely. The marginal teeth are 2 to 4 millimeters long and the flower clusters are 4 to 12 centimeters long. The first description of this subspecies by Susan Carter was published in 1996.
