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.

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.

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.

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.

This article presents and describesPlantago humboldtiana, an extremely narrow endemic rheophytic new species from a waterfall in Corupá, Santa Catarina state, southern Brazil. The new species is unique in presenting a combination of type-G antrorse trichomes on scapes, pendulous inflorescences and 1-seeded pyxidia. Only one population is known to exist, despite intensive search efforts in nearby, similar environments. Its conservation status is assessed as critically endangered (CR) as the only known population is restricted to a dramatically small area, and is subject to extreme fluctuation due to occasional floods, and also to intense visitation by tourists, which can disturb its fragile habitat. We also present an updated identification key to the species ofPlantagothat occur in Santa Catarina. The recent description of three narrow endemic, threatened new species ofPlantagoin Santa Catarina, which is the Brazilian state with its flora best studied, highlights the need for more taxonomic research, especially in the neotropics.

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.

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.

Abstract—While studying Urticaceae from the southern region of Brazil, we found two new species, Pilea tenebrosa and Pilea acanthoides, which were collected in the states of Santa Catarina and Paraná, respectively. These species are here described, illustrated, and compared to morphologically similar species. An identification key to the species of Pilea in southern Brazil also is provided.

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.
