= Calathea taeniosa Jorissene (1876: 83) ≡ Phyllodes taeniosa (Joriss.) Kuntze (1891: 697) ≡ Goeppertia taeniosa (Joriss.) Borchsenius & Suárez (2012: 634) . syn.nov. Type (lectotype, designated here):— Jorissene (1876: t. 5).

= Calathea hirta Ravenna (2004: 46) ≡ Goeppertia hirta (Ravenna) Borchsenius & Suárez (2012: 631) . syn.nov. Type:— BRAZIL. Minas Gerais: Estação Biológica de Caratinga, 20 November 1984, P.M. Andrade & M.A. Lopes 512 (holotype BHCB 7578!).

Notes:— Goeppertia widgrenii is recognized by the hirsute peduncle, bracts externally hirsute to glabrescent and internally glabrous; one bracteole per cymule, with the same size of the sepals; corolla tube, petals and sepals glabrous; large outer and cucullate staminodes, both obcordate and white with a yellow spot in the middle.

Jorissene (1876: 83) described Calathea taeniosa based on cultivated material of Jacob-Makoy, who nurtured various specimens of Marantaceae from Brazil. Field collections and examination of herbarium material conducted by the first author has revealed a wide coloration range of the leaves blade of this species: entirely green; white-banded green on adaxial side and purple on abaxial (as the description of C. taeniosa ); or entirely green on adaxial side with the abaxial side purple. Given this variation, Calathea taeniosa and its combinations should be considered synonyms of Goeppertia widgrenii .

Ravenna’s description (2004: 46) of Calathea hirta reported the same diagnostic characters as those given by Körnicke for C. widgrenii . The analysis of the type specimen of Calathea hirta confirms the identity of the two species. In conclusion, Calathea hirta and combinations should be therefore considered synonyms of Goeppertia widgrenii .
