description
Vegetative characteristics
Aeonium lindleyi forms perennial and densely branched small shrubs that reach heights of up to 50 centimeters. The smooth shoots reach a diameter of 3 to 15 millimeters. They are lightly downy, sticky and not patterned like a reticulum. The rather flat rosettes have a diameter of 4 to 9 centimeters. The inner leaves are more or less upright. The yellowish green to dark green, obovate or obovate-spatulate leaves are blunt at their tips and wedge-shaped or narrowed at the base. Your slightly to clearly downy hairy, sticky leaf blade is 2 to 4.5 inches long, 0.6 to 1.6 inches wide and 5 to 7 millimeters thick.
Inflorescences and flowers
The inflorescence is a racemose panicle . Your flower-bearing part is 2 to 7 inches long and 3 to 9 inches wide. The inflorescence stalk is 1 to 9 inches long. The eight- to nine-fold flowers are on slightly downy-haired flower stalks 1 to 10 millimeters in length. Their sepals are downy-haired. The yellow, narrow elliptical or lanceolate, pointed petals are 5 to 7 millimeters long and 1.5 to 2 millimeters wide. The stamens are bare.
Chromosome number
The chromosome number is for aeonium lindleyi var. Viscatum 2n = 36.
Systematics and distribution
Aeonium lindleyi is common in the Canary Islands . Aeonium lindleyi var. Lindleyi grows in the northeast of Tenerife at altitudes of up to 1000 meters, but mostly between 200 and 500 meters. Aeonium lindleyi var. Viscatum is widespread in the east of the island of Gomera at altitudes of about 100 to 900 meters.
The first description by Philip Barker Webb and Sabin Berthelot was published in 1840. Synonyms are Sempervivum lindleyi (Webb & Berthel.) Webb ex Christ (1888) and Sempervivum tortuosum var. Lindleyi (Webb & Berthel.) Kuntze (1891).
A distinction is made between the following varieties :
- Aeonium lindleyi var. Lindleyi
- Aeonium lindleyi var. Viscatum (Bolle) HYLiu
Aeonium lindleyi var. Viscatum
The differences to Aeonium lindleyi var. Lindleyi are: The leaves are 3 to 4 millimeters thick and densely covered with very short (up to 0.4 millimeters) multicellular hairs. The flowers are seven to nine and their petals are lanceolate, pointed and 5 to 7 millimeters long and 1 to 1.5 millimeters wide.
The first description as an independent species Aeonium viscatum was in 1859 by Carl August Bolle . Ho Yih Liu introduced this as a variety to Aeonium lindleyi in 1989 . Synonyms are Sempervivum viscatum (Bolle) Christ (1888), Sempervivum tortuosum var. Viscatum (Bolle) Kuntze (1891) and Aeonium lindleyi subsp. viscatum (Bolle) Bañares (2008).
