Petrorhagia been introduced to other continents. Petrorhagia Petrorhagia is a small genus of annual and perennial plants of the pink or carnation family, mostly native to the Mediterranean region. The genus is often referred to as Tunica, which is an obsolete synonym. It is low-growing with wiry stems and narrow, grass-like leaves. The flowers are small, in clusters similar to members of the genus "Dianthus", in pink, lilac, or white. "Petrorhagia saxifraga" is the tunic flower or coat flower, similar to Baby's Breath, but shorter, and used in rock gardens. These plants are mainly native to Eurasia, but some species can
Stenanthium "Stenanthium" in the southeastern United States: "S. macrum" and "S. tennesseense". Stenanthium Stenanthium is a North American genus of flowering plants in the tribe Melanthieae of the family Melanthiaceae. Featherbells is a common name for plants in this genus. Molecular phylogenetic studies in the 21st century have resulted in number of changes to placements within this tribe. Three species were removed from the genus to "Anticlea" and two or three (depending on whether "S. leimanthoides" is maintained as a separate species) added from "Zigadenus" sensu lato, the deathcamases. (See also Phylogeny of Melanthieae.) Members of "Stenanthium", as currently circumscribed, may
