A new species of Clematis (Ranunculaceae) from the Southern Brazilian Plateau is described here. The species shares similarities with C. denticulata and C. ulbrichiana, but can be distinguished mainly by the staminate partial inflorescences in compressed cymes (false whorls), pyriform staminate flower buds, and fewer carpels. Along with the descrip...
A proposal to change the conserved type of Ipomoea was published in December 2020, and recommended by the Nomenclature Committee in 2023. This was done in the light of the possible negative consequences for a name change in the crop sweetpotato, which risk our proposal would significantly minimize. Recently, Muñoz‐Rodríguez & al. have published a r...
Knowledge on biodiversity is fundamental for conservation strategies. The Brazilian Pampa region, located in subtropical southern Brazil, is neglected in terms of conservation, and knowledge of its biodiversity is fragmented. We aim to answer the question: how many, and which, species occur in the Brazilian Pampa? In a collaborative effort, we buil...
The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiver-sity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxo-nomic impediment to biodiversity research and conservation planning. The taxonomic impedi...
The Porto Alegre Botanical Garden (JBPA) aims at the conservation of native flora in Rio Grande do Sul and represents one of the main green areas in the city. Through periodic collections, we made a floristic inventory of the naturally occurring climbers in JBPA. For each one of the species, the attributes growth form, climbing mechanism and disper...

In this guide, 50 climber native species that are frequently found in the area of Porto Alegre Botanical Garden are illustrated, in order to promote knowledge of the local biodiversity, facilitating the recognition of plants by visitors.
The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...
RESUMO Cuscuta é amplamente distribuído e possui aproximadamente 200 espécies de parasitas volúveis. Estima-se que ocorram 26 espécies no Brasil, porém, não há estudos atuais publicados para a flora do país. Por meio de extensa revisão bibliográfica, de materiais de herbários e expedições a campo, foram reconhecidos 15 táxons de Cuscuta na Região S...
Proposal to change the conserved type of Ipomoea, nom. cons. (Convolvulaceae)
The genus Cuscuta L. (Convolvulaceae) are holoparasitic plants with cosmopolitan distributions, and they are usually difficult to identify. Based on several new field collections, we present three new floristic records from this genus in Central-West Brazil. Cuscuta platyloba Progel and Cuscuta partita Choisy are cited for the first time from Mato...
Most studies concerning climbing plants have focused on lianas, forest ecosystems, and tropical regions. Thus, the
majority of existing information is not relevant to all climbing plants (lianas and vines) or all ecoregions of the world
(forested and non-forested). We provide an update on floristic and distributional data available for climbing pla...
The Global Strategy for Plant Conservation (GSPC) was established by the Conference of Parties in 2002 to decrease the loss of plant diversity, reduce poverty and contribute to sustainable development. To achieve this overarching goal, the GSPC has established a series of targets, one of which is to ensure that plant diversity is well understood, s...
An updated inventory of Brazilian seed plants is presented and offers important insights into the country’s biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, sh...

A new species of Cuscuta (Convolvulaceae: Cuscuteae) from South America is described, illustrated, and studied under light and scanning electron microscopy. Cuscuta taimensis is similar to Cuscuta racemosa, but differs in having oblong to elliptic calyx lobes and a circumscissile capsule.
This study present the species of Evolvulus that occur in the three states of southern Brazil. Was carried out an extensive literature review and national and international herbaria. Nine species of Evolvulus were found in southern Brazil: Evolvulus barbatus Meisn., E. filipes Mart., E. glomeratus Nees & Mart., E. latifolius Ker-Gawl., E. linarioid...
Studies concerning Convolvulaceae in southern Brazil have revealed many novelties, such as new species and range extensions. In the present paper, three new species are described: Calystegia brummittii, Convolvulus ensifolius and Ipomoea mirabilis. Descriptions, illustrations and data on species distribution and conservation status are provided.
Merremia Dennst. ex Endl. comprises about 60 species widely distributed in the tropics and subtropics of both hemispheres. Among the 14 species occurring in Brazil, nine were confirmed for the Southern region: M. cissoides (Lam.) Hallier f., M. digitata (Spreng.) Hallier f. var. digitata, M. digitata var. elongata (Choisy) D.F.Austin & Staples, M....
Summary
Ipomoea L. is the most speciose genus of the Convolvulaceae, comprising c. 140 species in Brazil. Three new species are described
and illustrated from Rio Grande do Sul and Santa Catarina states: Ipomoea pampeana P. P. A. Ferreira & Miotto, I. riograndensis P. P. A. Ferreira & Miotto and I. sulina P. P. A. Ferreira & Miotto.
Cattleya presents about 120 species distributed in tropical and subtropical regions of the Americas. In its current delimitation, Cattleya also encompasses the Brazilian species formerly placed within the genera Laelia and Sophronitis, as well as the species of a number of recently segregated genera. This contribution deals with this genus in Rio G...
