Type.

Brasil. Glaziou 7999 (in herb. Berol.) (holotype: B! [B100242212]; isotypes: S! [S-R-6620], K! [K00494720]; P! [P00753728, P00753729]).

The holotype (B100242212) is the single sheet of Glaziou 7999 at the B herbarium. It is from Brazil, undated, lacks a more precise location, and was indicated in the protologue as deposited at the B herbarium. The holotype consists of several plants and dried material that was used by Nilsson (1892) to describe the species. Smith and Downs (1968) cited the collection Glaziou 7999 at the Stockholm herbarium (S R-6620) as “type”, but because Nilsson (1892) cited the B collection, the only sheet of this collection there, the S sheet must be considered as an isotype. Other isotypes were examined for the present study at K (K00494720) and P (P00753728, P00753729), all of Glaziou 7999, despite having annotations which give differing locations. The exsiccate K00494720 indicates that it is from Rio de Janeiro and P00753728 has a different indication to São Paulo, Campos Bocaina. However , the sheet P00753729 and the holotype (B100242212) were labeled only to Brazil, without mention of locality .

These disagreements in location attribution are thought to have occurred when Glaziou’s duplicates were distributed to the different herbaria.
