The genus Peperomia is represented by eight species in Uruguay: P. catharinae, P. comarapana, P. hispidula, P. increscens, P. pereskiifolia, P. psilostachya, P. tetraphylla and P. trineuroides. Peperomia psilostachya is reported for the first time for the flora of Uruguay, from material collected in moist hillside and riverside forests from the northeast and east of the country. Three new synonyms are proposed: P. arechavaletae var. arechavaletae as synonym of P. trineuroides, P. arechavaletae var. minor of P. tetraphylla and P. trapezoidalis of P. psilostachya. 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.

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.

The Praxelinae comprises two genera—Praxelis and Chromolaena—and 19 species in Rio Grande do Sul, the southernmost State of Brazil. This is the first taxonomic treatment of these genera in the state according to their current circumscriptions. Chromolaena squarrosoramosa is formally reported for the first time for the flora of the state. The names C. callilepis and C. paraguariensis are used for the first time to refer to species previously known as Eupatorium polyanthum and E. angusticeps. Eupatorium angusticeps, considered in previous studies endemic to Rio Grande do Sul and probably extinct, is synonymized under C. paraguariensis and has its geographical range extended. Two neglected names, C. elliptica and C. latisquamulosa, are re-established, and C. umbelliformis is synonymized under C. elliptica. Furthermore, C. rhinanthacea is recollected for the first time after 40 years, and C. gentianoides is rediscovered in the state after almost 200 years of the original collection. Identification key and morphological descriptions, as well as distribution maps, field photographs, illustrations and general comments on the biology, ecology and identification of the species are provided.

The genus Mucuna comprises approximately 105 tropical and sub-tropical species, with the highest diversity occurring in the Paleotropics. In the Neotropics, 13 new species have been described recently and a number of regional floras have been published. A recent floristic treatment for Colombia has summarized the Mucuna species found in the Neotropics, but since then many new species and new geographical records have been published. A complete taxonomic treatment of all neotropical species and an identification key to all neotropical taxa is currently lacking. The aim of this study is to present a complete taxonomic account of the species of Mucuna occurring in the Neotropics. Descriptions of 25 taxa (24 species and one variety) are included in the treatment, including type specimen details, synonymy, illustrations, distribution maps, and preliminary conservation assessments for each species, together with a species identification key.

Abstract—Rogiera (Guettardeae, Rubiaceae) is a Neotropical genus distributed from Mexico to northern South America that includes shrubs, treelets, or trees, which were previously treated in the taxonomically controversial and confused Rondeletia complex. Rogiera can be recognized among other Rubiaceae by the combination of multiflowered inflorescences, heterostylous flowers, quincuncial corolla aestivation, a hairy ring at the corolla mouth, and capsular fruits with loculicidal dehiscence. Despite the recent taxonomic circumscription of Rogiera there is not a comprehensive taxonomic treatment to it. Moreover, regional floristic treatments disagree on the species circumscriptions, with discrepancies in the number of species of Rogiera from 11 to 20. Based on molecular and morphological evidence studied on field and herbarium specimens, we present a taxonomic revision of Rogiera. We recognize ten species; Mexico is the center of diversity with nine species, four of them endemic. An identification key, descriptions, distribution maps, nomenclatural history, phenological data, and illustrations of all the species in the genus are provided for the first time. Several names required lecto- or epitypifications designated here.

Werneria is a neotropical genus belonging to the tribe Senecioneae (Compositae) that is mainly distributed through the highlands of the Andes. Only a single species, W. nubigena, has a trans-Andean distribution and reaches the Tacaná Volcano in southern Chiapas (Mexico). The traditional concept of Werneria was significantly narrowed at the end of the twentieth century after segregating several species and accommodating these mostly in the genus Xenophyllum. As currently circumscribed, it includes rosettiform or scapiform species characterized by usually displaying involucral bracts that are fused at the base, supplementary bracts commonly absent, usually radiate but sometimes discoid or disciform capitula, white or yellow ray corollas (when present), a balusterform filament collar, and style branches that are truncate and have a crown of sweeping hairs. The first modern, comprehensive revision of this genus recognizing 27 species is presented here. Werneria heteroloba and W. obtusiloba are synonymized with W. pinnatifida, and W. acerosifolia is synonymized with W. staticifolia. Moreover, five infraspecific names and three supraspecific names are synonymized. Detailed descriptions, distribution maps, photographs of living plants (except for W. cochlearis), and a list of all specimens examined are provided for each accepted species. An identification key to the species and a list of exsiccatae are also given. Eight species are illustrated, two of them for the first time. The following names are lectotypified: Werneria brachypappa Sch. Bip., W. caespitosa Wedd., W. calyculata Turcz., W. canaliculata Sch. Bip., W. carnulosa A. Gray, W. densa Benth., W. disticha Kunth, W. glaberrima Phil., W. glandulosa Wedd., W. heteroloba f. microcephala Rockh., W. mandoniana Wedd. ex Klatt, W. nubigena Kunth, W. nubigena var. caulescens Wedd., W. nubigena var. dombeyana Wedd., W. orbignyana Wedd., W. orbignyana var. breviradiata A. Gray, W. orbignyana var. longifolia Rockh., W. pectinata Lingelsh., W. plantaginifolia Wedd. ex Klatt, W. pygmaea var. caespitosa Wedd., W. rhizoma J. Rémy, W. solivifolia Sch. Bip., W. staticifolia Sch. Bip., W. staticifolia var. celmisioides Wedd., and W. villosa A. Gray. The names Werneria knocheae Perkins, W. minima Walp., W. minima var. pygmaea Walp., and W. stuebelii Hieron. are neotypified, and an epitype is designated for W. glandulosa. At the supraspecific level, the name Werneria sect. Integrifoliae Rockh. is typified.

A taxonomic revision of Anthriscus (Apiaceae, tribe Scandiceae) in Turkey was carried out. The genus Anthriscus is represented by four sections and eight taxa, including six species with three non-typical infraspecific taxa in that territory, grouped into four sections: i) A. sect. Anthriscus (A. caucalis var. caucalis and A. tenerrima var. tenerrima); ii) A. sect. Cerefolium (A. cerefolium var. trichocarpa); iii) A. sect. Caroides (A. kotschyi); and iv) A. sect. Cacosciadium (A. lamprocarpa subsp. lamprocarpa, A. lamprocarpa subsp. chelikii, A. sylvestris subsp. sylvestris and A. sylvestris subsp. nemorosa). A new taxon, A. lamprocarpa subsp. chelikii, was found and published as a preliminary result of the present revisionary study. Some new characters such as length of filament and petal, and the ratio of fruit length to its beak length are used in the identification key for the first time. New localities of some taxa were found and their distribution areas are expanded. According to all morphological findings on Turkish Anthriscus, a new description of the genus was carried out. The taxonomic treatments for all taxa include type, synonyms (when present), morphological descriptions, phenology, and distribution areas (worldwide and local), habitats, phytogeographic region, conservation assessment and specimens examined. A new identification key for the sections and all Turkish species of the genus Anthriscus is reported, and illustrations and distribution maps in Turkey are also given for eight taxa.
