The genuses Paliurus and Jovibarba are what types of plants?
Jovibarba Jovibarba ("beard of Jupiter") is a small genus of three species of succulent flowering plants in the family Crassulaceae, endemic to mountainous regions in the southeastern quadrant of Europe. The genus is sometimes classified as a subgenus of "Sempervivum", to which it is closely related. "Jovibarba" have pale-greenish-yellow or yellow actinomorphic flowers with about six petals, while "Sempervivum" have generally pinkish flowers with around twice as many petals, which open more widely than jovibarba flowers. The common name hen and chicks is applied to some "Jovibarba" species (and also species in several other genera).
Cornaceae Cornaceae is a cosmopolitan family of flowering plants in the order Cornales. It contains approximately 85 species in two genera, "Alangium" and "Cornus". They are mostly trees and shrubs, which may be deciduous or evergreen, although a few species are perennial herbs. Members of the family usually have opposite or alternate simple leaves, four- or five-parted flowers clustered in inflorescences or pseudanthia, and drupaceous fruits. In northern temperate areas, Cornaceae are well known from the dogwoods "Cornus".
