Trillium vaseyi, the sweet wakerobin[5] or sweet beth, is a spring flowering perennial plant which is found only in the southeastern United States, primarily in the southern part of the Appalachian Mountains but with a few populations farther south.[4][6][7][8]
Description
[edit]Sweet wakerobin has among the largest flowers in the trillium family, with red petals up to 7 cm long. It grows in rich woods, sometimes on riverbanks but other times on steep slopes.[9]
Taxonomy
[edit]Trillium vaseyi was named and described by the American botanist Thomas Grant Harbison in 1901.[3] Its type specimen was collected in the mountains of North Carolina in 1878.[10] The specific epithet vaseyi honors George Richard Vasey,[11][12] son of the American botanist Dr. George Vasey. The younger Vasey collected hundreds of plants in California and North Carolina during the period 1876–1881.[13]
Trillium vaseyi is a member of Trillium subgenus Trillium, commonly called the erectum group, a closely related group of seven species in the southeastern United States: Trillium cernuum, Trillium erectum, Trillium flexipes, Trillium rugelii, Trillium simile, Trillium sulcatum, and Trillium vaseyi. Natural hybrids are common within this group.
Conservation
[edit]As of April 2023[update], the global conservation status of Trillium vaseyi is listed as vulnerable and near threatened by NatureServe and IUCN (resp.).[1][2] It is critically imperiled in Alabama.
