This delightful crevice-plant native to Tenerife, Canary Islands, forms tight clumps of globular heads to 1 cm or so in diameter. Individual leaves are obovate and about the size of doughnut sprinkles. The flowers are jewel-like but not often seen, especially when the plant is grown in shade where it seems to do best. We grow it under the bench in our shade house along with shade-tolerant haworthias. Some authors consider this to be a synonym of M. muralis Hook. f. Divisions of HBG 73050, a plant received from Jack Catlin, Nov 3, 2003. $5.
