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]
Dudleya, commonly known as liveforevers is a genus of succulent plants in the stonecrop family, Crassulaceae, consisting of about 68 taxa in southwestern North America. The species come in multiple forms, some large and evergreen, others cryptic and deciduous. The flowers of Dudleya have parts numbered in 5, and when fruiting are filled with tiny, ovoid or crescent-shaped seeds.

The Santa Clara Valley dudleya, endemic to the Santa Clara Valley region in the southern San Francisco Bay Area, was listed on February 3, 1995, as an endangered species.

Taxonomically, this species is a highly variable complex of polymorphic and polyploid plants, closely related to numerous neighboring species such as Dudleya farinosa, Dudleya greenei and Dudleya palmeri. It is delimited from neighboring species on an arbitrary basis of distribution and chromosome number, and is not immediately separable from the other species it approaches.
