Gymnocalycium affine Repka spec. nov.
Repka, R. (2010) Gymnocalycium affine Repka sp. nov. - A neglected species of the northern part of Province Córdoba (Argentina). Cactus and Succulent Jounal, 82(6): p. 2-8
Abstract: Herein the new species Gymnocalycium affine is described, belonging to the G. robustum aggregate of the subgenus Gymnocalycium. It differs from similar and related species by its elongated areoles of 7-11 thin, mostly straight and radially outspread spines, without a coloured base, and rather robust pericarps about as long as the pale-pink corolla. Its distribution range, as it is known to date, is the northern part of the province of Córdoba (Argentina), approximately between the towns of San Pedro Norte and San Francisco del Chañar. It grows on flat pastures and in low hills on permeable soils formed by disintegration of granite and covered by degraded open shrub communities of the Chaco Serrano formation.

Gymnocalycium gertii V. Gapon et Schelkunova spec. nov.
Gapon, V.; Schelkunova, N. (2010) W poiskach Gymnocalycium papschii H. Till. Kaktus-Klub, 3(1): p. 46-51
Abstract: After a thorough field research and study of literature it became apparent that there is certain confusion with Gymnocalycium papschii H. Till. Plants from San Javier and Loma Bola growing on the western slopes of Sierra de Comechingones in the Argentinean province of Córdoba are different taxa. The differences between gymnocalyciums from this region are reviewed here.
A corrected diagnosis for G. papschii H. Till and the description of G. gertii V.Gapon et Schelkunova are proposed here. G. gertii differs from G. papschii H. Till emend. V.Gapon et Neuhuber in more cylindrical stem, more lengthened areolas, more numerous light and capilliform radial spines, larger flowers and a larger (up to 21 mm in length) ovary. The new species is named after a well-known Austrian expert Gert Neuhuber.

Abstract: The alliance of Gymnocalycium megatae Y. Itô is discussed. Two new combinations as subspecies are proposed: G megatae subsp. megatae (Cárdenas) and G. megatae subsp. matoense (Buining & Brederoo) H. Till & Amerh. G. megatae subsp. zecheri Amerh. is described as new to science.

Abstract: In the paper we publish the description of a new species: Gymnocalycium morroense Kulhánek, Repka et J. Proch.; including its ecology, chorology, taxonomy and variability. A table of morphological features distinguishing the species from relatives and similar species of subgenus Gymnocalycium, e.g. G. poeschlii, G. nataliae and G. berchtii and a distribution map of the species is attached.

Abstract: Gymnocalycium parvulum subsp. agnesiae F. Berger is proposed as a new taxon from the Argentinian province Córdoba. It represents the earliest diverging lineage within its alliance and is restricted to a small, probably relic area.
Typus: Argentinien, Prov. Córdoba, zwischen Ischilin Viejo und Las Palmas, 950 m s.m.; leg. Berger Be 00-175/751, 20.11.2000 (CORD, holo).
