Typification of the Linnean species of Saxifraga

WEBB, D. A., 1987. Typification of the Linnean species of Saxifraga. Types (mainly lectotypes) arc assigned to all the species of Saxifraga described by Linnaeus. There are 38 names in all, of which one is now assigned to Bergenia, one is known to be a hybrid, three have been rejected in the past as nomina ambigua, one was later reduced to synonymy by Linnaeus himself, while 32 are accepted as valid species today. Three have been previously typified by Pugsley, one by Steam and one by the author; for the others the types are newly proposed here. Nineteen names are typified from the Linnean herbarium in London (LINN), three from the Linnean herbarium in Stockholm (S), seven from the Burser herbarium at Uppsala (UPS), one from the Tournefort herbarium in Paris (P), and eight from illustrations cited by Linnaeus in synonymy. Lists are appended of all specimens of the genus in the Linnean herbaria in London and Stockholm and the Burser herbarium at Uppsala, and a determination is given for each specimen, though in some cases these can only be tentative. The specimens include 15 species which Linnaeus did not describe, though in the case of five he probably regarded them as varieties.
