Solanum physalidicalyx Bitter var. integrascens Bitter, Repert. Spec. Nov. Regni Veg. 11: 213. 1912. Type. Argentina. Salta: [Dtto. La Caldera], Pasaje del Río Juramento, P.G. Lorentz & G. Hieronymus [no number cited] (no explicit type material located; likely homotypic with species).

Solanum physalidicalyx Bitter var. plurilobulatum Bitter, Repert. Spec. Nov. Regni Veg. 11: 213. 1912. Type. Argentina. Salta: [Dtto. La Caldera], Pasaje del Río Juramento, P.G. Lorentz & G. Hieronymus [no number cited] (no explicit type material located; likely homotypic with species).

Type.

Argentina. Salta: [Dtto. La Caldera], Pasaje del Río Juramento, Feb 1873, P.G. Lorentz & G. Hieronymus 364 (holotype: B [destroyed]; lectotype, designated by Barboza et al. 2013, pg. 262: GOET [GOET003574]; isolectotypes: CORD [CORD00004269], DR [DR054234], US [00027741, acc. # 282274]).

Distribution.

Bolivia and Argentina.

Notes.

Type material for the varietal names coined by Georg Bitter in the original publication of S. physalidicalyx ( Bitter 1912) may correspond to duplicates of the type collection of the species itself, making all three names homotypic. In describing var. integrascens Bitter (1912) states "var. integrifolia quod in descriptione specie pro typo habui" [var. integrifolia I had in the description of the type of the species] suggesting this name at least is based on Lorentz & Hieronymus 364. Bitter often used duplicates with minor leaf variations as material for describing infraspecific variation ( Knapp 2013). None of the duplicates of these Lorentz and Hieronymus collections from Salta have annotations in Bitter’s hand, and we have found no other collections of S. physalidicalyx made by Lorentz and Hieronymus from "Pasaje de Juramento".
