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 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 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.

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.

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 ciliatifolia, a new species from Santa Catarina, southern Brazil. We treat the species as a member of Begonia sect. Pritzelia, and discuss its differences to related species. Due the species small area of occurrence and the very specific habitat, the new species is assessed as critically endangered according to IUCN criteria. Additionally, we present a distribution map, field photographs and a key to the species of Begonia with peltate leaves and corniculate fruits of South Region of Brazil.

We describe here Hoehnea grandiflora, a rare, critically endangered new species of Lamiaceae from high-elevation bogs in southern Brazil. The new species is similar to H. scutellarioides and can be distinguished by its shape and size of leaves, as some floral features. Its conservation status is assessed as Critically Endangered, because the new species is known from only one population located in an environmentally unprotected area. Urgent conservation studies and actions are necessary to prevent the extinction of this species. We also provide an identification key to the five species in the genus Hoehnea.

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.

A new species of Magnolia subsect. Talauma (“jomcoj”), Magnolia ottoi, is described and illustrated. The conservation status of this new species is proposed as critically endangered (CR) according to IUCN criteria. An identification key and a map with the distribution of the new species and other species of Magnolia subsect. Talauma from Guatemala and neighboring areas (Honduras and Chiapas, México) is also presented. Our field research also unveiled the Mayan Q’eqchi’ ancestral taxonomic knowledge which differentiates magnolias of two different subsections, Magnolia and Talauma, based on wood quality and properties. They consistently distinguished them as “coj” and “jomcoj” respectively.
