Stephaniella paraphyllina J.B. Jack , Hedwigia 33: 11, 1894.

Type:—CORDILLERA ARGENTINO-BOLIVIANIS. Cienega, alpine region, 1873, P. G . Lorentz s.n. (lectotype [here designated] G-00120479!, isolectotype G!, M!) .

Note:—From Paul G. Lorentz’s collections of 1873, Jack (1894) described the genus Stephaniella with S. paraphyllina as the type species. The type locality (Cienega in alpibus Argentino-Bolivianis, in solo glaresolutoso) was cited, but no type specimens were mentioned.

Original material of Stephaniella paraphyllina ( G 00120478, G 00120479, G 00115491, G; M-0182810, M), collected by Lorentz in 1873, was examined. Schmitt and Winkler (1968) considered the specimen at M to be a syntype, but it is not clear if this specimen is part of the same or different gatherings because Lorentz did not number his gatherings. Nonetheless, for nomenclatural purposes I conclude that all of the above original elements are part of a single gathering. It should be noted that the moss collection at B, which likely contained Lorentz’s best material, was destroyed ( Stafleu & Cowan 1981: 157). At least one specimen in the Lorentz’s collection at G (G- 00115491) was likely examined by Jack as it was stamped with his herbarium name.
