“…Among the new chromosome records for the other families, stand out Amorimia septentrionalis, Eugenia zigzag and Utricularia quelchii. Amorimia was the only Neotropical genus of the Malpighioid clade (Malpighiaceae) without chromosome records (Almeida, 2018). The number 2n = 20 for A. septentrionalis presented here is similar to that found in closely related genera, especially Malpighia L. and Mascagnia (DC.)…”

Malpighiaceae has undergone unprecedented changes in its traditional classification in the past two decades due to several phylogenetic studies shedding light on the non-monophyly of all subfamilies and most tribes and genera. Even though morphological characters were used to reconstruct the last molecular generic phylogeny of Malpighiaceae, a new classification system has never been proposed for this family. Based on a comprehensive review of the last twenty years of published studies for this family, we propose a new classification system and provide a taxonomic synopsis for Malpighiaceae based on molecular phylogenetics, morphology, palynology, and chemistry as a baseline for the systematics, conservation, and taxonomy of this family worldwide. Malpighiaceae currently comprises two subfamilies (Byrsonimoideae and Malpighioideae), 12 tribes ( Acmanthereae , Acridocarpeaetrib. nov., Barnebyeaetrib. nov., Bunchosieaetrib. nov., Byrsonimeae, Galphimieae, Gaudichaudieae, Hiptageae, Hiraeeae, Malpighieae, Mcvaughieaetrib. nov., and Ptilochaeteaetrib. nov.), 72 genera (incl. Mamedeagen. nov.), and 1,499 accepted species (715 of which are currently under some kind of extinction threat). We present identification keys for all subfamilies, tribes, and genera, a full morphological description for the proposed new genus, the re-circumscription of ten genera alongside the needed new combinations, the proposition of several new synonyms, the typification of several names, and notes on the taxonomy, distribution, conservation, and ecology up to the genus rank. Morphological plates are also provided to illustrate the immense diversity of morphological traits used in the new classification and synopsis.

“…Recently, Almeida et al (2017) proposed two new subgenera for Amorimia; A. exotropica was placed in the subgenus Amorimia. As the epithet makes reference to, this species is distributed outside the tropics and, according to Almeida (2018), it should be regarded as Endangered in Brazil. It is easily recognized by the hairy petals on the abaxial surface, bracts with 1-2 basal glands (Fig.…”

“…Despite recent taxonomic and phylogenetic studies concerning the family Malpighiaceae (Almeida et al 2016(Almeida et al , 2017Almeida 2018), in the South Region of Brazil, floristic studies of the family are still lacking. Monographs of Malpighiaceae genera and extensive taxonomic revisions generally do not account for specimens that are in border areas between biogeographical regions and do not cover particular morphological data in addition to not providing taxonomic tools applicable at a regional scale.…”

Malpighiaceae in southern Brazil: Identification keys for genera and updates on species richness

et al. 2021

Recent studies have contributed to a better understanding of the circumscription of some genera of Malpighiaceae and the overall diversity of the family in Brazilian tropical ecosystems. In southern Brazil, however, this important group of lianas and shrubs still has not been fully categorized. The present study provides identification keys based on floral and fruit morphology for the 23 genera reported from southern Brazil. The importance of the number of styles and the position and shape of the stigmas for the recognition of genera was confirmed. Illustrations of morphological characteristics used in the keys and notes about taxonomy, species richness and distribution are provided. It should be noted that the occurrence of some Malpighiaceae genera that are represented by only one species in the southern region, such as Bronwenia, Camarea and Heladena, are not yet cited in the Flora do Brasil 2020 database. A total of 95 species were confirmed and documented by voucher specimens. Banisteriopsis pseudojanusia, Heteropterys dusenii and Peixotoa catarinensis, occur exclusively in southern Brazil and are classified as “Critically Endangered”, “Vulnerable” and “Endangered” in the Brazilian Red List, respectively.
