Type. Rio San Francisco and Rio Mboacia, Minas Gerais, Brazil, teste Jorge Marc grave (Hist. Nat. Bras. 92. 1642), but Urban interprets the type locality as Haiti or Martinique, based on pl. 136 of Plumier, Icon. ed. Burm. 1757.
Typification of the Linnaean species of Genipa americana must be interpreted on the basis of pre-Linnaean references. Urban (Fedde Rep. Beih. 5: 67. 1920) places the type locality in Hayti or Martinque on the basis of Plumier’s leones pl. 136 (edit. Burmannus). On the other hand, the pre-Linnaean references refer mainly to Brazilian collections as the earliest localities, and the evidence for this is strongly supported. The most frequent reference is made to Jorge Marcgrave’s Historia Natural do Brasil (p. 92). Here Marcgrave states that the Janipaba or Jenipapo (source of the name Genipa) is found wild in Brazil on the Rio San Francisco and Rio Mboacica (in the present state of Minas Gerais) and that the leaves shaped like a “lingua de boi” are shining and light green above, dark green and not shining below, and measure “uma pe ou pe’e meio de comprido.” Plumier (Pl. Am. Fasc. Pr. 1: 127. 1757) likewise refers to Marcgrave. Other pre-Linnaean references to Brazil as the source of the plant under consideration include the following: Plukenet (Alm. Bot. Mant. 99. 1700); Linnaeus (Hortus Cliffort. 76. 1737) with reference to “Crescit praesertim in Brasilia”; Bauhin (Hist. Pl. 1, liber III, cap. V: 253. 1650) refers to its Brazilian derivation and to the change from the Brazilian name of Junipappeiyuva to Genipat, as previously indicated by Clusius (Exot. Lib. 1, Cap. 10: 10. 1605). These early references, combined with the fact that all the earlier Brazilian collections examined up to 1840 (including those of Gardner, Blanchet, and Claussen) were obtained from the states of Bahia, Minas Gerais, and Pernambuco, would point to eastern and southeastern Brazil for the type locality of Genipa americana. These eastern and southeastern Brazilian collections of the earliest Brazilian collectors in those localities show the leaves with a mainly glabrous lower midrib, lateral nerves, and surface, sericeous interior of the calyx tube, and a conspicuously hirsute pubescence on the interior of the corolla tube and base of corolla lobes.
Genipa oblongifolia R. & P., described from material collected from Pampahermosa, is represented in the herbarium of F by a fragment from the type at MA of a single leaf. The lower surface of this leaf is glabrous, while the midrib and lateral nerves are sparsely to moderately strigillose, conforming more or less to the original description of Ruiz & Pavon to the leaves as “leviter pubescentibus” on the “nervo et venis transversalibus.” A specimen from the Boissier Herbarium at G, identified as G. oblongifolia, and collected from Peru (Palo Colorado de Chicoplaya no. 394), shows a similar type of leaf with the surface below glabrous, but the midrib and lateral nerves sparsely to moderately appressed-strigillose. The calyx tube interior of this specimen is densely sericeous. Other material examined from Peru, as cited above, likewise shows the calyx tube interior densely sericeous and the midrib and/or lateral nerves of the lower side of the leaves with a slight pubescence of short ascend-ing or longer spreading pilose hairs. I can find no real differences between the Peruvian material of Genipa oblongifolia and material from southeastern and eastern Brazil referred to G. americana. The locality of Pampahermosa of Ruiz and Pavon is indicated on modern maps as in the Department of Loreto, Municipio Ucuyali, along the Río Ucuyali. From near this locality and others in the Department of Loreto has been collected adequate material showing variation in the glabrity and pubescence of the lower midrib and nerves. Some of the specimens from southern Brazil show some lower midribs and nerves pubescent as in G. oblongijolia. There are transitional specimens which are difficult to place, with variation present between extremes of completely glabrous lower midribs and lateral nerves to pubescent midribs and/or nerves, the surface itself remaining glabrous. It has seemed best, therefore, to combine the G. oblongijolia variation with the completely glabrous type, placing them both under the “leaves glabrous” category, used by authors to describe the leaves of G. americana. In both the West Indies as well as in southern, eastern, and southeastern Brazil, this variation of glabrity and pubescence of the lower midrib and lateral nerves, combined with a glabrous lower surface, is manifest. Therefore, whether one interprets the type locality of G. americana as Hayti or Martinique on the one hand, or southeastern or eastern Brazil on the other hand, the same type of variation is encountered. By combining G. oblongijolia and G. americana, there is eliminated any possible future difficulty in the interpretation of G. americana as a taxon having the lower surface of the leaf blades glabrous but with midrib and lateral nerves glabrous to pubescent, leaving only the extremely pubescent-leaved variation of G. caruto H.B.K. to be separated.
Both G. barbata Presl and G. excelsa Krause must be considered conspecific with G. americana var americana. In G. barbata the isotype at NY shows the lower leaf surface glabrous. In G. excelsa the lower surface of the leaf blades is glabrous, but there is appressed pubescence on the lateral nerves, and like G. barbata, the interior of the calyx tube is densely sericeous.
