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.

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.

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.

A total of 46 species and two varieties of the traditionally interpreted genus Orthotrichum are currently known to occur in China. They represent five genera, including Orthotrichum (29 species), Lewinskya (14 species and two varieties), and Nyholmiella and Leratia that are represented by a single species each. The fifth genus Florschuetziella, also consisting of only one species, F. scaberrima, is an entirely neglected representative of the China’s moss flora. A list of all accepted taxa is presented and for each taxon all literature records and herbarium specimens are enumerated for provinces in which they have been recorded, and their distribution is mapped. A key to determination of Chinese orthotrichalean mosses is presented. A chronological list of 63 species and varieties and two designations, O. catagonioides and O. microsporum which have never been validly published, reported from China in the years 1892–2020 is presented. Four species, Orthotrichum brasii, O. hooglandii, O. elegans and O. gymnostomum are excluded from the bryoflora of China and Lewinskya affinis var. bohemica and Orthotrichum schimperi are recorded for the first time from this country. Phytogeography of the Chinese taxa of the orthotrichalean mosses is considered and they are grouped into eight phytogeographical elements and five sub-elements.

AbstractThe conservation status of threatened taxa may be obfuscated by the detection of cryptic species complexes, in both vertebrate and invertebrate species. African dwarf crocodiles (Osteolaemusspp.) are hunted throughout their range but their conservation status is unknown. Few population assessments have been carried out and there has been a taxonomic revision of the number of species in the genus. The similar morphologies ofOsteolaemus tetraspisandOsteolaemus osbornipose a challenge for conservation in Cameroon, where they are still managed as a single species. Nocturnal spotlight surveys were conducted in three regions during August–November 2010 and December 2011–February 2012 to provide population assessments ofO. tetraspisandO. osborniand raise awareness of the two species in Cameroon. The mean encounter rates ofO. tetraspisandO. osborniwere 1.02 ± SD 1.34 (65 individuals in 39 surveys) and 0.61 ± SD 0.38 (three in four surveys) crocodiles per km, respectively. TheO. tetraspispopulation comprised juveniles predominantly and had a male-biased sex ratio. The fewO. osbornidetected comprised both adults and juveniles. Both species are threatened in Cameroon, based on low encounter rates, young population structures and the threats of habitat loss and hunting pressure. This study provides distribution maps and serves as a baseline to quantify population trends and inform conservation strategies.

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.

The orchid genus Phloeophila is distributed from southern Mexico to Brazil and Bolivia, as well as Cuba. A taxonomic revision including the three Phloeophila species present in Ecuador is presented. Morphological characteristics, an identification key, maps of known localities and illustrations of the species are also included. In Ecuador, species of Phloeophila are only known from the Amazonian rainforests, growing from 890 to 1600 meters of altitude. Phloeophila condorana is described as a new species based on specimens collected in the Ecuadorian province of Zamora-Chinchipe and compared to Phloeophila nummularia. Phloeophila nummularia is reported for the first time in Peru. A lectotype for Pleurothallis echinantha is selected.
