description

Vegetative characteristics

Monanthes minima is a perennial , single or rarely sprouting rosette plant . Their shoots are short, strong and more or less caudiciform . They have a diameter of 5 to 10 millimeters. The dense rosettes are 5 to 10 millimeters high and reach a diameter of 10 to 35 millimeters. The narrow, obovate leaves are rounded or slightly tapered and narrow into a long stem-like base. Your leaf blade is 6 to 15 millimeters long, 1 to 3 millimeters wide and 1 to 3 millimeters thick. Their surface is densely glandular and downy with hairs less than or equal to 0.3 millimeters in length, sticky and somewhat papillary .

Inflorescences and flowers

The inflorescence consists of simple, glandular-downy-haired flower stems and is regularly branched. The five to seven-fold flowers are on glandular-hairy flower stalks 3 to 9 millimeters long and reach a diameter of 2 to 3 millimeters. Their narrow, elongated, pointed petals are 1.4 to 2.6 millimeters long and 0.4 to 0.6 millimeters wide. The nectar flakes are 0.9 to 1.4 millimeters long and 1.3 to 1.6 millimeters wide. Your blade is somewhat bilobed, wrong heart-shaped, frayed or finely toothed and clearly nailed.

Distribution and systematics

Monanthes minima is common in the south and east of the Canary Island of Tenerife at altitudes of 80 to 800 meters.

The first description as Petrophyes minima by Carl August Bolle was published in 1859. Konrad Hermann Heinrich Christ placed the species in the genus Monanthes in 1888 .
