Further Examination of the Geographic Range of Niles’s Buckwheat. The native buckwheat Eriogonum corymbosum (Benth.) is widely distributed throughout the southwestern United States, forming a complex of eight varieties. Eriogonum corymbosum var. nilesii (Reveal), Niles's wild buckwheat, is a primarily yellow-flowered taxon known only from Clark County, Nevada. A previous genetic study by our research group found that Niles’s wild buckwheat is genetically distinct from other E. corymbosum varieties. Here, we examine 14 recently sampled yellow-flowered populations that are morphologically similar to variety nilesii (11 outside Clark County, Nevada), comparing them to six populations of previously determined taxonomic varieties. We used AFLPs to examine 457 individuals at 105 AFLP loci. Of the new populations, we found four to be variety nilesii, four variety aureum, three variety glutinosum, two apparent hybrids involving varieties aureum and nilesii, and one a more distantly related admixture. Our results extend the range of Niles’s wild buckwheat in Nevada from the region including Las Vegas Valley and the Muddy Mountains west of the Virgin River, north to Coyote Springs in northern Clark County, and northeast to Toquop Wash in southeastern Lincoln County. This extended range is confined to the Mojave region, and the known populations of variety nilesii remain limited.
