Aeonium percarneum is a species of the genus Aeonium in the family of thick-leaf plants (Crassulaceae). The specific epithet percarneum is derived from the Latin words per- for 'very' and carneus for 'flesh-colored' and refers to the reddish colored leaves of the species.
description
Vegetative characteristics
Aeonium percarneum forms perennial and slightly branched subshrubs within 1 meter, the growth heights of up. The ascending shoots reach a diameter of 7 to 20 millimeters. They are bare and reticulate. The rather flat rosettes have a diameter of 8 to 20 centimeters. The dark green, bluish tinged, inverted lanceolate-spatulate leaves are pointed towards their tip and wedge-shaped at the base. Your balding leaf blade is 4.5 to 10 inches long, 2 to 4 inches wide and 3 to 6 millimeters thick. The leaf margin is often slightly serrated, often covered with curved eyelashes up to 1 millimeter in length and usually reddish variegated.
Inflorescences and flowers
The dome-shaped inflorescence is 10 to 30 inches high and 10 to 25 inches wide. The inflorescence stalk is 8 to 20 inches long. The eight- to ten-fold flowers are on slightly downy-haired flower stalks 1 to 3 millimeters in length. Your sepals are weakly downy hairy. The whitish, lanceolate, pointed petals are pink in the middle and are 7 to 8 millimeters long and 1.2 to 1.8 millimeters wide. The stamens are sparsely weakly downy-haired.
Chromosome number
The number of chromosomes is 2n = 36.
Systematics and distribution
Aeonium glutinosum is widespread on the Canary Island of Gran Canaria at altitudes of around 100 to 1300 meters.
The first description as Sempervivum percarneum by Richard Paget Murray was published in 1899. Charles-Joseph Marie Pitard and Louis Proust put the species in the genus Aeonium in 1909 .
Synonyms are Aldasorea percarnea (RPMurray) hort. ex Haage & Schmidt (1930) and Aeonium percarneum var. guiaense G.Kunkel (1977).
