6. Pabstiella savioi Luer & Toscano (2011: 379)

( Figure 6C )

Type: — BRAZIL. Espírito Santo: Serra do Castelo, near Venda Nova do Imigrante , November 2002, S. Caliman under M. Frey 614 (holotype: HUEFS 187229 ! in spirit).

= Pabstiella setibensis Chiron & Ximenes Bolsanello (2016: 204) , syn. nov.

Type: — BRAZIL. Espírito Santo: Guarapari, Setiba , 22 May 2013, G. Chiron 13309 (holotype: MBML 49993 !)

Taxonomic Discussion: —The holotype of Pabstiella savioi is an alcohol-preserved specimen deposited at HUEFS, prepared from a cultivated plant collected in the Serra de Castelo , Espírito Santo. The holotype of Pabstiella setibensis , deposited at MBML, was collected in the same Brazilian state but from a coastal forest growing on sandy soils known as Restinga . When compared side by side, it becomes evident that these two plants, collected from different vegetation types within the Atlantic Rainforest, represent the same species.

The plants exhibit high variability: the leaves may be lanceolate, as in P. setibensis , or elliptical, as in P. savioi , but their inflorescences and floral morphology remain consistent. The dorsal sepal has recurved apical margins, and the petals have an abruptly acuminate apex, floral characters that distinguish this species from similar taxa.

Several collections of P. savioi from the Restinga forests in the states of Espírito Santo and Rio de Janeiro are deposited at MBML and RB, most of which were identified as P. rampastorhyncha ( Barbosa Rodrigues 1881: 55) Kollmann (2010: 96) . P. rampastorhyncha is an obscure taxon for which neither a description of the lip is provided in the protologue nor an illustration in the original color painting. Moreover, as with other species described by J. Barbosa Rodrigues, no herbarium materials are available for revision. Therefore, we advise caution in the use of this name until a consensus can be reached on its true identity.
