Ferreira 85 ( RB barcode 01179848 !, designated here; isoepitypes RBR barcode RBR00056639 !, SPF [n.v.]) . Notes:— Cocculus platiphyllus , basionym of Chondrodendron platiphyllum , was published by Saint-Hilaire (1825) with a brief diagnosis and a direct reference to plate “ Aug. de S. Hil. Plant. us. Bras. nº. XLII ”, which was effective published later (see Saint-Hilaire, 1827 ). In the latter publication, a detailed morphological description is presented along with an illustration, comments on etymology, popular uses and the citation of type locality Minas Novas, state of Minas Gerais , Brazil . Two sterile specimens of the gathering Saint-Hilaire s.n. collected in Minas Novas are deposited at the herbarium P. The line drawing presented by Saint-Hilaire (1827 , pl. 42, also our Fig. 1A ) undoubtedly represents the specimen Saint-Hilaire s.n. (P barcode P00748524) ( Fig. 1B ). The other specimen, Saint-Hilaire s.n. (P barcode P00048605), is a chimera, being composed of the original sterile gathering of Saint-Hilaire s.n. mixed with a drupelet fragment, likely associated with the gathering of Richard s.n. (P), collected in the state of Rio de Janeiro , and which is one of the type of Cocculus platiphyllus var. ildefonsianus . This specimen bears also two identification tags with Saint-Hilaire’s handwriting identifying the specimen as “ Cocculus platiphylla var. α Aug.”, and as “ Cocculus platiphylla var. ss ildefonsiana Aug. et Tul.”. The latter has one anonymous annotation indicating that tag does not belong to the specimen (In French: “ Cette étiquette n´apparente pas a cet specimen ”, on the label). Based on this information, the specimen Saint-Hilaire s.n. (P barcode P00748524) is designated here as lectotype ( Fig. 1B ), the same specimen illustrated in Saint-Hilaire (1827) . As stated above, these type specimens are sterile and have only a few young leaves with base cordate, an unusual characteristic in Chondrodendron platiphyllum . Therefore, we also designated here as epitype the specimen Feliz & Ferreira 85 (RB barcode 01179848), which is with developed leaves and many drupelets ( Fig. 2 ).
