description
Vegetative characteristics
Monanthes laxiflora is a perennial , somewhat woody and diffuse to densely branched small shrub that reaches heights of 10 to 20 centimeters. The prostrate or ascending shoots are later often drooping. They are slim, somewhat twisted and have a diameter of 2 to 5 millimeters. The cross-opposed, obovate or elliptical, sometimes almost circular leaves are occasionally more or less clustered near the shoot tips. Their rounded or slightly pointed blade is 5 to 12 millimeters long, 3 to 8 millimeters wide and 3 to 6 millimeters thick. There is usually a central longitudinal furrow on the upper side of the leaf. Its surface is bare and partially covered with whitish wax flakes.
Inflorescences and flowers
The terminal inflorescence is regularly branched. The six to seven-fold flowers reach a diameter of 4 to 5 millimeters. They stand on bare or glandular-hairy flower stalks that are 4 to 12 millimeters long. Their elongated, pointed petals are 2.9 to 4.4 millimeters long and 0.9 to 1.4 millimeters wide. The nectar flakes are 1.3 to 1.7 millimeters long and 1.5 to 2.2 millimeters wide. Your blade is bilobed, trimmed or inverted heart-shaped, tiny notched or rarely frayed and clearly nailed.
Distribution and systematics
Monanthes laxiflora is common in the Canary Islands of Lanzarote , Fuerteventura , Gran Canaria , Tenerife and Gomera at altitudes of 50 to 1100 meters.
The first description as Sedum laxiflorum by Augustin Pyramus de Candolle was published in 1828. Joseph Friedrich Nicolaus Bornmüller placed the species in the genus Monanthes in 1906 .
