Taxonomic Comments
Brouillet and Gornall (2007) and FNA (vol. 8, 2009) transfer Saxifraga nelsoniana to Micranthes nelsoniana (D. Don) Small. FNA also includes Saxifraga nelsoniana ssp. pacifica in S. nelsoniana ssp. porsildiana as Micranthes nelsoniana var. porsildiana, while Kartesz (1994) here treats them as distinct.
