Resumo

Martinella Baill. is a genus of Neotropical lianas in tribe Bignonieae (Bignoniaceae). The genus is monophyletic and well supported by morphological and molecular characters. Members of Martinella are characterized by a continuous interpetiolar ridge surrounding the stem, bilobed or 4-5-parted calyces, and minute triangular prophylls of the axillaiy buds. Generic circumscription remained unchanged since the description of the genus, although unclear species limits remained. Based on extensive fieldwork, herbarium work, and a molecular phylogenetic hypothesis for the genus, we here recognize five species of Martinella. Of these, three were recognized in earlier treatments for the genus, while two represent new species described here, Martinella lanuginosa Kataoka \& L.G.Lohmann, sp. nov. and Martinelli tomentosa Kataoka \& L.G.Loh mann, sp. nov. Martinelli iquitoensis A.Samp. is treated as a synonym of M. insculpta Sprague \& Sandwith. In addition, one second-step lectorype is designated for Bignonia martini DC., and neotypes are designated for Davantha longisiliqua Miers and Martinella gollmeri K.Schum. This work provides a full taxonomic treatment for Martinella, including a complete list of synonyms, morphological descriptions, illustrations, photographs, distribution maps, conservation status, and comments for all five species recognized.
