Sclerolobium urbanianum Harms ( Harms 1904 [1903]: 23)

Type.

BRAZIL - Rio de Janeiro • Rio D'Ouro , près de l’eau; 24 Aug. 1879; fl.; A.F.M. Glaziou 10683; lectotype (designated here): P [P00350582!]; isolectotypes: F frag. [V0093906F!], F [V0057933F!], G [G00367865!], K [K000264436!], P [P0035083!, P0035084!], R [R000008767!], S [S-R-9145!] .

Notes.

Harms (1904) refered to Glaziou 10683 as the type material without specifying its herbarium origin. Nine syntypes were found (see ICN Art. 9.6; Turland et al. 2018), one glass negative from B herbarium (Grimé and Plowman 1987). The material from P (P00350582) is designated as the lectotype, as it is well-conserved, is in the best condition, and is in accordance with the protologue and the photograph at F (Fig. 4E, J ).

There is a record of Glaziou material at G, which is a branch of Sclerolobium urbanianum in the same phenological state as the other syntypes of S. urbanianum , but has manuscript data from Glaziou 10643, determined as Swartzia flaemingii Raddi, collected in Tijuca, Rio de Janeiro, in 1880 (Fig. 4F, K ). There is only a single record of Sclerolobium urbanianum made by Glaziou, so this specimen was considered part of the type material, as previously noted by H.C. Lima in October 2010 (Fig. 4L ).

Nomen dubium

Sclerolobium macrophyllum Vogel ( Vogel 1837: 397)

Vogel described Sclerolobium macrophyllum in the same work and on the same page as S. paniculatum Vogel and refered to a record made by A.P. Silva Manso and J. Lhotsky "in campis" from Mato Grosso, Cuiabá (Brazil). Since Vogel worked in Berlin ( Stafleu and Cowan 1979), it is possible he saw specimens available at B, which might have been later destroyed during World War II ( Merril 1943).

In the search for possible type specimens in the herbarium databases, two specimens supposedly collected by A.P. Silva Manso and J. Lhotsky and identified as S. macrophyllum were found. One of them is a specimen deposited in R under the number n°2664, composed of two sheets, both with a label from the Museu Nacional with the name " Sclerolobium aureum Benth." and the locality "Mato Grosso. Cuyaba", in addition to another label signed by Van Der Werff, in which he states that the sheets could be isotypes of Sclerolobium macrophyllum . In the original description, Vogel mentioned "Flores non vidi", and the specimens deposited at R show a complete inflorescence in bloom and do not match the protologue in some regard, so they cannot be the original material that Vogel used to describe this species. After examining this material at R, we concluded that these specimens represent Tachigali vulgaris L.G.Silva & H.C.Lima.

The other specimen deposited at US, with a label from the Museum botanicum Berolinense (B) annotated as " Sclerolobium macrophyllum Vogel", has no mention of the locality indicated by Vogel, nor the fruits described by him and does not match the protologue in some regard. As a result, this specimen cannot be used for the purpose of the application of the name Sclerolobium macrophyllum , and it may not be part of the type material, making this name a nomen dubium.
