Taxonomic revisions in Fridericia (Bignonieae, Bignoniaceae) II: the “Neomacfadya” clade
2022
Kaehler, Miriam | Lohmann, Lúcia G.
Fridericia is a large genus of neotropical lianas with a complicated taxonomy. The genus is monophyletic and well supported by molecular characters, but lacks distinctive morphological synapomorphies, complicating its recognition. Species of Fridericia are distributed among six well-supported clades. As part of a series of taxonomic revisions of each clade of Fridericia, we present a taxonomic revision of the “Neomacfadya” clade. This group is broadly distributed through the Neotropics and includes species with glandular fruits and long-tubular calyces that are usually laterally split. We recognize 11 species for which we provide an identification key, typifications, morphological descriptions, illustrations, phenology, maps, comments on distribution and habitats, as well as suggest the conservation status for all species. We lectotypify six names (Arrabidaea ateramnantha, A. craterophora subvar. glabrescens, A. craterophora subvar. velutina, Bignonia hispida, Scobinaria amethystina and S. japurensis). We correct the typification of A. lenticellosa Bureau & K. Schum. and B. arthrerion, provide a second-step lectotypification for B. pearcei and a neotypification for Paragonia schumanniana. We also correct information associated with the type of A. oligantha and synonymize this name in F. japurensis. We further reject A. craterophora var. obtusifolia and exclude one name previously treated in Fridericia (Tecoma moritziana). Citation: Kaehler M. & Lohmann L.
