The correct name of R. vulgaris Weihe & Nees

The correct name of R. vulgaris Weihe & Nees is R. commutatus G.Braun, because there is an older homonym of R. vulgaris: R. vulgaris Tourn. ex J. de Vries, Natuurkundige en ophelderende aanmerkingen 3: 196 (1779). See Adansonia 38(1): 34. De Vries' publication is explicitly claimed as a scientific book for a scholarly explication of the ideas of Martionet's catechism of nature.

Krünitz, Ökonomisch-technologische Encyclopädie 128: 301 (1820) published the same taxon once again.

The validating description is in vol. 6 (1784: 779-784), whereto Krünits 1820 refers.

R. commutatus Braun is a weak form of R. vulgaris Weihe & Nees but belongs to the same species (see Weber 1985).
