Sclerolobium duckei Dwyer ( Dwyer 1957: 109)

Type.

BRAZIL - Rio de Janeiro • Itatiaia, Parque Nacional, Lote Hansen , borda da mata com o roçado; 1 Oct. 1940; fl., fr.; W. Duarte de Barros 48; lectotype (designated here): RB n°45677 [3 sheets, RB00585813!, RB00585812!, RB00539707!]; isolectotype: SP [SP000943!] .

Notes.

Dwyer (1957) indicated that the type material of S. duckei is deposited in herbarium R (T.: Duarte de Barries 48 (R)!). However, he refered to the Systematic Botany Section of the Botanical Garden of Rio de Janeiro as R, thus to the herbarium RB. The correction for the location of the type material is clarified in the present paper (see ICN Art. 9.2; Turland et al. 2018).

The specimen deposited in RB under the number 45677 is composed of three sheets. The first of which has the original herbarium labels and a determination label written by Dwyer, together with a barcode (RB00539707; Fig. 3A ), and it is composed of two branches: one with leaves and the other with a leaf, inflorescence, and flowers. The second sheet (RB00585812; Fig. 3B ) has a duplicate distribution stamp (Fig. 3C ) indicating that the SP herbarium received one sample (Fig. 3D ), and it is composed of a branch with leaves and a fruit. The third sheet (RB00585813; Fig. 3E ) has a branch with two leaves and an envelope of fragments with leaflets, inflorescence side branches, flowers, and a fruit. The curator of the RB herbarium distributed part of the RB type collection to other herbaria in 2008 (Rafaela Campostrini Forzza pers. comm.), so the SP specimen was previously studied by Dwyer, making it impossible to consider the set deposited in RB to be seen as a holotype assembled in more than one preparation, as it is now only part of the whole. Therefore, the gathering located at RB under the number 45677 is chosen as the lectotype, as it is the complete material and what the author first designated.
