Eriogonum tiehmii, known as Tiehm's buckwheat, is a species of flowering plant endemic to the Silver Peak Range of Esmeralda County, Nevada in the United States.[2][1] Its only known population is at high risk of destruction due to mining activities.[1]
Taxonomy
It was first formally named by American botanist James L. Reveal in 1985 in The Great Basin Naturalist.[3][4] Reveal named the plant for Arnold "Jerry" Tiehm who first collected the species in 1983.[3]
Description
Eriogonum tiehmii is a small, perennial herbaceous plant, growing about 30 cm (12 in) across and up to 16 cm (6 in) tall with blue-grey leaves. The leaves are 1 to 2 cm (0.4 to 0.8 in) long and 5 to 8 mm (0.2 to 0.3 in) across with white or grey hairs on both surfaces, sometimes losing the hairs on the upper surface as it ages.[3]
Conservation status
Tiehm's buckwheat is considered critically imperiled ("at very high risk of extinction or elimination") due to its small population and threat from mining activities. Mining exploration has increased the prevalence of invasive species in its habitat. As of 2020[update], current mining plans are expected to destroy approximately 50–70% of the known population.[1][5]
