Sedella (formerly Parvisedum) is a small genus of annual flowering plants in the family Crassulaceae. There are approximately 7 species,[1] all native to California, United States, one with a distribution extending into Oregon. These are petite succulent plants growing a few centimeters tall and bearing tiny yellowish or brownish flowers. Mock stonecrop is a common name for these plants.[2]
These plants are diminutive annuals, they grow erect and are glabrous (without hairs). The leaves are early-deciduous, sessile, and shaped oblong-elliptic to ovoid. The tips of the leaves are rounded to obtuse. The inflorescence has 1 to 2 flowers in 0 to 3 branched cyme, sub-sessile. There are 5 sepals and 5 petals. The petals are pale to bright or green-yellow, with a midrib that is often more or less red.[3]
The genus was described by Nathaniel Lord Britton and Joseph Nelson Rose during their reorganization of the North American Crassulaceae.[4]
The name is the Latin diminutive of Sedum. The name Parvisedum is a synonym.[3]
