The genus Pelargonium (Geraniaceae) includes ca. 281 species, organised into 16 sections and four subgenera. Since the last revision of the genus by Knuth in 1912, recent revisions have been completed for all of the currently recognised sections of the genus with the exception of three, sections Ciconium, Otidia and Peristera. Pelargonium sect. Peristera is lectotypified, and a taxonomic revision of the southern African species of this section is presented, recognising 11 species, of which one, P. sessiliflorum, is described as new. An identification key is provided along with nomenclature, descriptions, distribution maps, habitat information, and conservation notes for the 11 recognised species, synonymising nine names.

ABSTRACT The taxonomic revision of Amorimia (Malpighiaceae) is presented, including typifications, and descriptions for all accepted species. The genus is endemic to Seasonally Dry Tropical Forests and Rainforests of South America, and its species can be distinguished by morphological details of leaves, indumenta, inflorescences, flowers, and fruits. This study includes an identification key for the subgenera and species of Amorimia, illustrations, distribution maps, conservation risk assessments, and comments on ecology, nomenclature, and taxonomy for all species. Additionally, I provide a key to differentiate Amorimia from the remaining genera of the Malpighioid clade.

In the present study, we presented a taxonomic revision of the genus Sorbaria (Sorbarieae; Amygdaloideae) with a new infrageneric classification. Moreover, we extensively reviewed various data for Sorbaria species, including previous anatomical, micromorphological, and palynological data. The new sectional classification was based on morphological, micromorphological, and palynological evidence, with two sections: sect. Sorbaria aut. and sect. Kirilowiana J.-H. Song & S.-P. Hong (sect. nov.). Overall, four species and five varieties (including two nomenclatural novelties) were recognized: S. sorbifolia (Linnaeus) A. Braun var. sorbifolia, S. sorbifolia var. glandulifolia J.-H. Song & S.-P. Hong, S. sorbifolia var. stellipila Maximowicz, S. pallasii (G. Don) Pojarkova, S. tomentosa (Lindley) Rehder var. tomentosa, S. tomentosa var. angustifolia (Wenzig) Rahn., S. kirilowii (Regel & Tiling) Maximowicz var. kirilowii, S. kirilowii var. arborea (C.K. Schneider) J.-H. Song & S.-P. Hong (comb. & stat. nov.), and S. kirilowii var. dubia (C.K. Schneider) J.-H. Song & S.-P. Hong (comb. nov.). Some illustrations and syntype were designated as the lectotype for several names. The classification was based on a comprehensive morphological examination of herbarium specimens, including field observations and observations of types, micromorphological, and palynological characteristics. In addition, we provided an identification key, diagnostic characteristics, full descriptions, comprehensive nomenclatural treatments and taxonomic notes (including complete synonymy), and distribution maps of Sorbaria species.

Lectotypes for P. arechavaletae, P. arechavaletae var. minor and P. tacuariana, and a neotype for P. herteri are designated. The taxonomic treatment includes synonymies used in Uruguay, morphological descriptions, distribution and habitat data, phenology, conservation assesment, observations, and material examined for each species treated. A species identification key, plant illustrations and distribution maps in Uruguay are provided.

It occurs throughout forests in tropical Africa and the highest species diversity is found in the Western Central African rain forests. A key for flowering material is provided, just like a synoptic key including 45 characters. Topics included in the revision are the history of the taxonomy of Monanthotaxis, morphology, leaf anatomy, floral biology, distribution and habitat, phylogeny and finally ethnobotany and phytochemistry. Each species is fully described including synonymy, notes on distribution, habitat & ecology, vernacular names, uses and a preliminary IUCN conservation status.

This paper presents a taxonomic revision and phylogenetic analysis of nine known species of the genus Phonoctonus Stål, 1853, distributed exclusively in the Afrotropical region. The revision and phylogenetic analysis were performed using morphological data. A full redescription for all species is provided, taxonomical problems are clarified, and diagnostic characters are presented and illustrated. Based on the analysis, thirteen species are recognised as valid: Phonoctonus bifasciatus stat. nov., P. caesar, P. elegans, P. fairmairei stat. nov., P. fasciatus, P. grandis, P. immitis stat. rev., P. luridus, P. lutescens, P. nigrofasciatus stat. rev., P. picta stat. nov., P. picturatus stat. rev., and P. principalis. New synonymies are proposed: Phonoctonus nigrofasciatus= P. fasciatus var. poultoni syn. nov., P. picturatus = P. fasciatus var. discalis syn. nov., and P. principalis = P. validus syn. nov. An identification key to separate the species, drawings of dorsal habitus, and distribution maps of all valid species are presented. Performed morphological phylogenetic analyses indicate monophyly of the genus Phonoctonus.

African Clade

Schoenus is a morphologically complex, predominately austral genus. The taxonomy of the southern African clade of Schoenus has received recent attention with the transfer of 24 southern African species into Schoenus from Tetraria and Epischoenus in 2017. A taxonomic revision in early 2018 both revised the taxonomy of the Schoenus compar—Schoenus pictus and allies group, as well as described three new species endemic to the Cape Floristic Region of South Africa. In addition, seven new species were described in early 2019 as part of a revision of the Schoenus cuspidatus group. Here, we build on this recent taxonomic work by providing descriptions for three new species (Schoenus bracteosus, Schoenus comparoides and Schoenus triticoides). We also provide a new name at species rank for a taxon previously named as a variety of Tetraria sylvatica. We present detailed species descriptions, distribution maps and an updated identification key.

The Andean genus Xenophyllum (Compositae, Senecioneae) is distributed along the high-Andes from northeastern Colombia to northern Chile and northwestern Argentina, mainly thriving in the paramo and puna ecoregions. It comprises suffruticose plants forming dense mats, hummocks, or clumps of erect stems. They are characterized by displaying involucral bracts fused at the base, supplementary bracts absent, and mostly radiate capitula with white ray corollas, seldom yellow or pink (disciform in one species). Traditionally, Xenophyllum species were treated as members of the genus Werneria, a morphologically close genus that includes rosettiform or scapiform perennial herbs. As currently circumscribed, Xenophyllum mostly differs from Werneria in having elongate stems. Herein, the first modern and comprehensive revision of the genus recognizing twenty-two species and two subspecies is presented. Werneria decumbens is synonymized with X. weddellii, as well as X. fontii with X. humile and X. oscartovarii with X. dactylophyllum. Likewise, four varietal names and two sectional names are proposed as new synonyms. Seven names are lectotypified, the name X. sotarense is epitypified, W. decumbens neotypified, and the supraspecific name W. sect. Integrifoliae Rockh. is typified. The combination X. crassum subsp. orientalecomb. nov. is made. Descriptions and distribution maps are provided for all accepted species, in addition to an identification key. Ten species are illustrated, three of them for the first time.
