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 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.

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.

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.

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.

We describe here Bertolonia lucernula, a new endemic species from the state of Espírito Santo, Brazil. It is only known from one locality, the “Área de Proteção Ambiental Mestre Álvaro”, in the municipality of Serra. The new species can be recognized by the branches and petioles covered with sessile and short-stalked glands and scattered unbranched trichomes, flat leaf blade surfaces covered only with sessile and short-stalked glands, small flowers with a widely campanulate hypanthium covered with the same trichomes as the petioles, calyx with membranaceous, truncate sepals, and short, triangular external teeth, asymmetric and obovate petals, with the apex covered with sessile and short-stalked glands on the adaxial surface. According to IUCN criteria, Bertolonia lucernula should be classified as Critically Endangered (CR).

Iucn Criteria

A new species of Calliandra (Leguminosae, Mimosoideae, tribe Ingeae) from a restricted locality of Campeche, Mexico is herein described and illustrated. The species appears to be closely related to C. molinae, a species from Honduras, El Salvador and Nicaragua, from which it may be distinguished by being allopatric, and by a more limited development of suberose bark in stems and branches, comparatively smaller leaflets, consistently glabrous leaflets and corollas, and by the scarcely villous pods. Calliandra mayana appears to be restricted to an extremely small seasonally flooded savannah surrounded by tropical deciduous forest and, based on IUCN criteria, it is provisionally considered Critically endangered.

Iucn Criteria

We propose that two populations previously referred to Hechtia epigyna, from the Mexican state of Hidalgo, represent a new species. Plants from the Hidalgo populations share the inferior ovary with Hechtia epigyna, an unusual trait in the genus, but they differ in their growth pattern (central vs. lateral inflorescence), characters of the adaxial foliar surface, petal color, and fruit position during dehiscence. We also provide a clarification on the typification of Hechtia epigyna. An assessment of the conservation status of the new species, Hechtia deceptrix following IUCN criteria resulted as CR (Critically Endangered).
