Nototriche is represented in Peru by 62 species and is the fourth megadiverse genus in the high Andes. In the context of the taxonomic treatment of this genus for the Peruvian flora, 25 names were identified that need to be typified to stabilize their nomenclature. For the nomenclatural treatment, the protologs are analyzed and the type material is...
Several species in the genus Oxalis occupy Peruvian fog oases (Lomas) with a significant habitat-adapted and endemic diversity. Acknowledging this aspect, the genus Oxalis is a conceivable group for evolutionary and biogeographic hypothesis testing; however, molecular resources for the genus still need improvement. We conducted a genome skimming ap...
Two recent fieldwork expeditions to Peru and Ecuador resulted in the finding of two Carex species (C. hypsipedos and C. sanctae-marthae) previously known from a single collection each, and of uncertain morphological and systematic affinities. We performed phylogenetic analyses using barcode molecular markers and a detailed morphological comparison...
Se describe e ilustra a Nototriche chancoae, una nueva especie de los Andes de Lima, Perú. Esta especie se relaciona con N. glacialis, N. nigrescens y N. congesta por presentar láminas flabeliformes, hipófilo piloso, lado interno del cáliz piloso hacia el ápice de los lóbulos y corola con tubo presente; se distingue por tener vaginas más anchas y l...
We present relevant records of nine species of sedges (Cyperaceae) for Peru. For the genus Carex , we present two new national records ( C. haematopus , C. lepida ), plus relevant data for another six hitherto poorly known species. We also present the first record of Trichophorum rigidum subsp. ecuadoriense for Peru.
Societal Impact Statement
Herbaria can be considered plant libraries, each holding collections of dried specimens documenting plant diversity in space and time. For many plant species, these are our only evidence of their existence and the only means of assessing their conservation status. Specimens in all herbaria, especially those in small and of...
Herbarium collections shape our understanding of Earth’s flora and are crucial for addressing global change issues. Their formation, however, is not free from sociopolitical issues of immediate relevance. Despite increasing efforts addressing issues of representation and colonialism in natural history collections, herbaria have received comparative...
Generic limits of the South American tribe Eudemeae are critically evaluated based on a thorough examination of morphology in light of the most extensive recent molecular phylogenetic studies using nuclear and plastid markers. As a result, only five genera (Alshehbazia Salariato & Zuloaga, Aschersoniodoxa Gilg & Muschl., Gongylis Theophr. ex Molina...
Lomas formations or "fog oases" are islands of vegetation in the desert belt of the west coast of South America, with a unique vegetation composition among the world's deserts. However, plant diversity and conservation studies have long been neglected, and there exists a severe gap in plant DNA sequence information. To address the lack of DNA infor...
El presente estudio analiza la distribución geográfica, el estado de conservación y la nomenclatura de la endémica peruana Pedersenia weberbaueri. La distribución de especies se modeló usando MaxEnt con base en datos de ocurrencia y variables bioclimáticas. Se evaluó el estado de conservación de la especie frente a las categorías y criterios de la...
Two high Andean taxa from South Peru, Viola ornata and Viola longibracteolata, are described and illustrated. During a series of ecotourism and botanical expeditions in the Moquegua and Arequipa regions, four populations of V. ornata and one population of V. longibracteolata were discovered. Both species are compared with morphologically similar sp...
The Andean region is one of the most biodiverse areas, displaying high levels of endemism and spatial turnover of species. Tribe Eudemeae includes nine genera and 40 species distributed from the northern Andes in Colombia to the southernmost portion of the Andes in Argentina and Chile. Here, we generated a species-level phylogenetic tree to study t...
Herbarium collections shape our understanding of the world's flora and are crucial for addressing global change and biodiversity conservation. The formation of such natural history collections, however, are not free from sociopolitical issues of immediate relevance.

Las lomas costeras son el resultado de la interacción entre
diversos factores de clima, suelo y relieve, y adoptan diversas
formas y composiciones dependiendo, entre otras causas,
de la distancia del mar, la altitud, la pendiente o condiciones
microclimáticas. Este frágil ecosistema se caracteriza también
por presentar condiciones ambientales extre...
The desert fog oasis ecosystem of Peru and Chile comprises numerous oases along 3000 km of the Pacific coastal belt, it hosts a highly endemic flora, providing vital ecosystem services and genetic resources. However, due to their marked seasonality and fog cover they are poorly mapped, greatly compromising their conservation. Here we redress this u...

Cremolobus is a genus of seven species distributed along the Andes from northern Argentina and Chile northward into Colombia, and it inhabits a variety of different environments from humid habitats, such as the Yungas in Bolivia and Argentina or the Andean Paramos in Colombia and Ecuador, to the arid regions of the Sechura Desert in Peru. This genu...

The genus Dicliptera (Justicieae, Acanthaceae) consists of approximately 150 species distributed throughout the tropical and subtropical regions of the world. Newly obtained chloroplast genomes (cp genomes) are reported for five species of Dilciptera ( D. acuminata , D. peruviana , D. montana , D. ruiziana and D. mucronata ) in this study. These cp...
Phylogenetic studies have shown that Schefflera, the largest genus of Araliaceae, is highly polyphyletic, comprising five non-sister clades within the family, and that the generic name must be restricted to a small group of Pacific Island species. In an effort to establish monophyletic genera for the other elements still remaining in Schefflera, ph...
Clinanthus inflatus (Amaryllidaceae) and Ismene parviflora are described from Ancash Department in Peru. The flower of C. inflatus is urceolate, and resembles that of Urceolina (Amaryllidaceae tr. Eucharideae), a unique morphology for the genus. Ismene parviflora, with its small, loosely formed, narrowly funnelform-tubular perigone with a ventricos...
The wetlands of the central coast of Peru have more than 100 species of vascular plants. Of them, Santa Rosa (Chancay, Lima) has one of the highest richness of vascular flora. Considering that the last inventory for this wetland was done almost 10 years ago, the objective of the present study was to update its vascular flora, updating the list and...

Distribution of the species at the...
The genus Machaerophorus includes three perennial species (M. arequipa, M. laticarpus, and M. matthioloides) inhabiting the southern Peruvian Andes. However, based on the morphological data, this genus has been reduced for more than one hundred years to synonymy of several genera of various tribes, and its phylogenetic placement using molecular dat...

Coastal wetlands, along with the lomas formations and riverine ecosystems comprise an important biological corridor along the Peruvian-Chilean coast. The objective of this work was to study the vascular flora of a wetland located between the districts of Carquín and Hualmay in the province of Huaura (Lima, Peru). There are 41 species of vascular pl...
The Peruvian genus Machaerophorus has long been reduced to synonymy of several genera of various tribes. With the discovery of two new species described below, M. arequipa and M. laticarpus, and availability of material for molecular phylogenetic studies, the genus is reinstated for the first time in over a century and included within the South Ame...
