Vegetative characteristics

Monanthes pallens is a perennial , individually growing or partially sprouting rosette plant . Their shoots are short or slightly elongated and more or less caudiciform . They have a diameter of 3 to 7 millimeters. The very dense rosettes usually consist of more than a hundred leaves. The rosettes are 7 to 15 millimeters high and reach a diameter of 10 to 40 millimeters. The narrow obovate leaves are pointed or slightly truncated and taper into a long, narrow base. The leaf blade is 5 to 18 millimeters long, 1 to 3 millimeters wide and 1 to 2 millimeters thick. Their surface is bald or occasionally covered with a few short (less than 0.1 millimeter long), glandular hairs . Towards the tip it is densely papillary .

Inflorescences and flowers

blossoms

The inflorescence consists of simple flower stems that appear laterally and is regularly branched. The five- to seven-fold flowers are on the glandular-hairy flower stalks 3 to 10 millimeters long and reach a diameter of 3 to 4 millimeters. Their narrow, elongated, pointed petals are 2.8 to 3.6 millimeters long and 0.5 to 0.8 millimeters wide. The nectar flakes are 1.1 to 1.6 millimeters long and 1.4 to 1.9 millimeters wide. Your blade is somewhat bilobed, obovate, finely toothed and clearly nailed.

Distribution and systematics

Monanthes pallens is widespread in the west of Tenerife and on La Gomera at altitudes of 50 to 1100 meters.
