“ Aspidosperma brevifolia ” Rusby, orth. var.
“ Aspidosperma cuyabense ” Müll.Arg., mss. in sched.
“ Aspidosperma cylindrocarpon var. genuinum ” Hassl. in Repert. Spec. Nov. Regni Veg. 12(325/330): 260. 1913, a designation not validly published.
Notes —Based on the works about Friedrich Sellow (Urban 1906; Herter 1945; de Moraes 2008) and information on other Aspidosperma species collected by Sellow (A. australe (B1645-c77?) and A. olivaceum (B1647-c777 )), we can speculate that Sellow’s collection of A. cylindrocarpon was also made on his third journey to Rio de Janeiro, São Paulo, and Minas Gerais states (Brazil). Additionally, on some labels is also handwritten “Ypanema”, which according to Urban (1906) narrows down the locality of “Rio Sorocaba, Ipanema (Real Fabrica de Ferro de S.J. Ipanema, 1.VI.1819 – 7.I.1820)” in São Paulo.
Also, between the two gatherings cited in the protologue of A. cylindrocarpon by Müller-Argoviensis (1860a), Woodson (1951) selected as the type “Sello s.n.” (Sellow 1650-780). However, since this gathering has more than one specimen, it was necessary to narrow Woodson’s (1951) typification electing the material with a visible collecting number as the second-step lectotype of A. cylindrocarpon (W No. 1889-0167639) (ICN article 9.17; Turland et al. 2018). Moreover, Müller-Argoviensis (1869) indicated the gathering Warming s.n. in the prologue of A. lagoense but did not cite in which herbarium the type would be deposited. Thus, we chose the best-preserved specimen from this collection as the lectotype of A. lagoense (C barcode C10005732) (ICN article 9.3; Turland et al. 2018). For that same reason, we chose lectotypes for A. brevifolium and A. cylindrocarpon var. macrophyllum. In the case of A. brevifolium, we elected the most complete specimen from the single gathering indicated by Rusby (1912) as the lectotype (NY barcode 00297951), while for A. cylindrocarpon var. macrophyllum we chose as the lectotype a specimen with flowers from the single gathering cited by Hassler (1913) (LIL barcode LIL001108) (ICN article 9.3; Turland et al. 2018).
Lastly, according to the ICN article 24.3 (Turland et al. 2018), designations of infraspecific taxa that were intended to include the type of the species to which they were assigned were not validly published whenever they had infraspecific epithets like “ genuinum ” (e.g., “ A. cylindrocarpon var. genuinum ”).
We are considering A. divaricatum as a synonym of A. cylindrocarpon once the main morphological characteristics of A. divaricatum overlap with those of A. cylindrocarpon, as the leaves with longer petioles (2–3.5 cm long) and brochidodromous venation and flowers with oblong corolla lobes.
