BRAZIL - Mato Grosso • in sylvis prope Cujaba Brasiliae meridionalis [ Cuiabá]; 1841; fl.; A.L.P. Silva Manso s.n. (Mart. Herb. Fl. Bras. n ° 1147); lectotype (designated here): K [K000264417!]; isolectotypes: BR [BR000000591529!, BR000000591352!, BR000000591562!, BR000000591595!, BR000000591598!], F [V0057930F!], G [2 sheets, G0367860!], M [M0215288!, M0215289!], NY [NY0022924!], P [P00835781!], W [W0004897!] .

Notes.

Tulasne (1844) published Sclerolobium rubiginosum from an unpublished manuscript by Martius (Mart. Herb. Fl. Bras.), and this name was later transferred to variety status by Bentham (1870) as Sclerolobium paniculatum var. rubiginosum . Thirteen specimens are now recognised in different collections. Tulasne likely saw the P specimen since the author dedicated himself to the P herbaria ( Stafleu and Cowan 1979), but there is no explicit reference to the holotype. The material from K (K000264417) is chosen as the lectotype because it is in a better condition and represents part of two phenological stages (young flowers and fruits; Fig. 4A, G ).

Oliveira-Filho (2006) made four new combinations for the Sclerolobium species native to Minas Gerais (Brazil) and circumscribed them under the genus Tachigali : T. denudata , T. duckei , T. pilgeriana , and T. subvelutina (Benth.) Oliveira-Filho. The author followed a consistent pattern in the new combinations, correctly cited the basionym (following ICN Art. 40.1; Turland et al. 2018), used the term "comb. nov." for each one, and, in a note, mentioned that the new combination transfered Sclerolobium to Tachigali , following Lewis et al. (2005). However, Oliveira-Filho (2006) did not followed this pattern when transferring Sclerolobium rubiginosum to Tachigali , referring to the name as "comb. ined." (unpublished combination) and did not made it clear in the note that a new combination is being proposed, as in the other names.

In independent non-serial work submitted to educational institutes to obtain a degree, "comb. ined." is regularly used to highlight that the name presented should not be considered valid but unpublished and provisional. These kinds of works are not effective publications without internal evidence to be considered as such, following ICN Art. 30.9 ( Turland et al. 2018).

Despite correctly citing the basionym, the name published by Oliveira-Filho (2006) cannot be considered valid but a provisional and unpublished name (see ICN Art. 36.1; Turland et al. 2018). The use of "comb. ined." should be interpreted in the same way as the use of "ad int. [ad interim, for the time being]" presented in ICN Art. 36.1, Ex. 6 ( Turland et al. 2018), and as the use of "comb. ined." in those independent non-serial work. Considering this, a new combination for Tachigali rubiginosa is proposed herein.
