During field works in Santa Catarina state, we found a new species of Chascolytrum that presents a bulb-like rhizome. This species is similar to Chascolytrum bulbosum, from Pampa biome, differing by glabrous leaf blades, inflorescences larger and laxer, longer spikelets and paleas glabrous between the keels. We additionally provide field and studio photographs and assess its conservation status according to IUCN criteria.

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.

This contribution presents and describes Siphocampylus baccae and S. sevegnaniae, two narrowly endemic new species from waterfalls and rocky cliffs in Santa Catarina state, southern Brazil. We assess the conservation status of both species as critically endangered (CR) according to the IUCN criteria. We present descriptions, photographs, a distribution map and taxonomic comments on the new species along with an identification key to the species of Siphocampylus that occur in Santa Catarina.

This contribution presents and describes Tradescantia schwirkowskiana, a narrow endemic new species from Santa Catarina state, southern Brazil. We assess here the conservation status of this new species as critically endangered, according to the IUCN criteria. We present here a complete description, illustrations and comments on the new species, along with an identification key to the species of Tradescantia that occur in Santa Catarina. Furthermore, we designate here a lectotype and an epitype for T. crassula, the morphologically-closest species to T. schwirkowskiana.

Valeriana iganciana, an endemic species from the Serra do Tabuleiro highlands of Santa Catarina state, southern Brazil, is described and illustrated. The new species shares morphological affinities with V. ulei, from which it is distinguished mainly by leaves with entire margin, by the cymose architecture of the inflorescence and by the triquetrous and elliptical fruits with annular to dentate calyx.

Pherania giupponii sp. nov. is herein described from a coastal island in Santa Catarina state, southern Brazil. The genus Pherania Strand, 1942, was hitherto monotypic and the type species, Pherania pygmaea (Sørensen, 1932), is known from the nearby mainland. A new diagnosis is given to Pherania and the geographic distribution of the two species is illustrated on a map.

This contribution presents and describes Tradescantia serrana, a new species from the edges of Araucaria forest in the highlands of southern Santa Catarina state, southern Brazil. Illustrations, photographs and a distribution map for the new species are provided. Here, we also typify T. umbraculifera, a species morphologically related to T. serrana, and present evidence against the synonymisation of T. schwirkowskiana with T. crassula proposed by Pellegrini et al. (2017). Furthermore, we extend the distribution of T. schwirkowskiana to Paraná state.

This contribution presents and describes Commelina catharinensis, a new, narrow endemic species only known from two very restricted areas of coastal vegetation in Santa Catarina state, southern Brazil. Both localities where this species has been collected are currently highly threatened by both legal and illegal urban advance. The new species classifies as endangered (EN) according to the IUCN criteria. We also provide here the first identification key to the species of Commelina that occur in Santa Catarina.

Here we describe a new species of Prosopanche from southern Brazil. This is the first report of Prosopanche in Santa Catarina state and for the Atlantic Forest region. We present field photographs, illustrations, ecologic and conservation comments on the new species. We contrast the morphology of the new species with the other Prosopanche species that occur in Brazil, P. bonacinai and P. caatinguicola. The new species is morphologically similar to P. bonacinai, which has anthers composed by 20–30 thecae, synandrium 15–25 × 6–8 mm and tepals 35–55 × 9–20 mm vs. anthers composed by 3–4 thecae, synandrium 5–6 × 3–4 mm and tepals 15–20 × 5–8 mm in P. demogorgoni.

In this work we describe Ludwigia humboldtiana, an extremely narrowly endemic new species from a waterfall system in Corupá municipality, Santa Catarina, southern Brazil. This is already the second plant species endemic to the area. The new species is morphologically most similar to L. caparosa, L. elegans, L. multinervia and L. peruviana but differs from those by a series of taxonomically important characters. We present field photographs, a distribution map and a detailed morphological account of the new species, discuss its morphology and taxonomy in relation to the morphologically most similar other species of Ludwigia, and assess its conservation status according to IUCN criteria.
