Eriogonum is the scientific name for a genus of flowering plants in the family Polygonaceae. The genus is found in North America and is known as wild buckwheat. This is a highly species-rich genus, and indications are that active speciation is continuing. It includes some common wildflowers such as the California buckwheat.
The common name umbrella plant can refer to several unrelated species:
Eriogonum nudum is a perennial shrub of the wild buckwheat genus which is known by the common name naked buckwheat or nude buckwheat.
Eriogonum fasciculatum is a species of wild buckwheat known by the common names California buckwheat and eastern Mojave buckwheat.
Oenothera lindheimeri, formerly Gaura lindheimeri, and commonly known as Lindheimer's beeblossom, white gaura, pink gaura, Lindheimer's clockweed, and Indian feather, is a species of Oenothera.
Eriogonum longifolium var. harperi, also known as Harper's buckwheat or Harper's umbrella plant, is a dicot of the family Polygonaceae, found in areas of nutrient-poor shale soils in Alabama, Kentucky and Tennessee. It lives inconspicuously in an immature vegetative stage for four or more years before developing a flowering stalk, then flowers and dies. It is listed as an endangered species by the state of Tennessee. It has eleven small populations in Alabama and five in Tennessee but its survival in Kentucky is uncertain. According to a leading expert, Professor James L. Reveal of the University of Maryland, its Kentucky population has been reportedly extirpated. Its 2006 Alabama Natural Heritage Program ranking was G4T2S1, demonstrating an opinion that it was "critically imperiled" in that state.
Opuntia engelmannii is a prickly pear common across the south-central and Southwestern United States and northern Mexico.
