Abstract—During a taxonomic treatment of Stryphnodendron (Leguminosae, Caesalpinioideae, mimosoid clade) for the Brazilian Flora 2020 Project, one new presumably critically endangered species from the Atlantic Forest domain was found, and is so far only known to western Espírito Santo state. Stryphnodendron flavotomentosum is described and illustrated, and information on its distribution, habitat, phenology, and preliminary conservation status is provided. Additionally, an identification key for the species of Stryphnodendron from the Brazilian rainforests is presented.

A new endemic and critically endangered species of Rudgea (Rubiaceae) from Southeastern Brazil is described and illustrated. Rudgea minutifolia Bruniera & Torres-Leite is distinguished by its small leaves, a character found in only a handful of species in this genus. The indumentum of the branches, leaves and stipules, low number of secondary veins, corniculate corolla lobes, and vinaceous to almost black mature fruits are also characteristic of this species. Discovered in a forest remnant within the Atlantic Rainforest domain in the south of Espírito Santo state, this species is found only in the municipality of Castelo, an area that has been recognized as prioritary for conservation. Besides the description, taxonomic comments, conservation status, images and illustrations are provided.

In this study, Fritillaria arsusiana (Liliaceae) is described and illustrated as a new species from Hatay province in southern Anatolia, Turkey. It is related to F. amana and F. hermonis by habitus features and broadly campanulate flowers, but differs mainly by its bulb shape and size, smaller leaf and flower features, and flower colour. It has also been morphologically compared with F. wendelboi, F. pinardii, and F. latakiensis. The detailed description, diagnostic characters, original photographs, geographical distribution, habitat and phenology, etymology, conservation status, and identification key of the new and the related species are presented in this study. IUCN conservation status of F. arsusiana is suggested as Critically Endangered (CR).

The authors describe, discuss, and illustrate Lymania involucrata, a new ornamental species from the Atlantic Forest in the municipality of Igrapiúna, Bahia, Brazil, here considered a critically endangered species. The new species is morphologically related to L. brachycaulis but clearly diffe According to Sousa rs from it by the well-developed, involucral primary bracts and the distinct shape and size of inflorescence, primary branches, and flowers. A map of the distribution of the species and taxonomic comments are presented.

A new species, Calea arachnoidea, which belongs to Calea sect. Meyeria, is hereby described and illustrated. This species occurs in the Serra Negra region, located in the southern portion of the “Zona da Mata” in the state of Minas Gerais, southeastern Brazil. Calea arachnoidea resembles C. quadrifolia, C. heteropappa and C. semirii, and its relationships with these species are discussed and an identification key for the species of C. sect. Meyeria in the state of Minas Gerais is provided. Additionally, photographs, a distribution map, comments about habitat and conservation status are provided.

Pternopetalum paucifoliolatum, a new species from Sixigou Scenic Area, Emeishan City, Sichuan Province, is proposed and described. Diagnostic morphological characters, full description, detailed illustrations, and a distribution map are provided. The new species is similar to P. porphyronotum in possessing the 1-pinnate leaves and the abaxially purple-red leaflets, but differs from the latter by shorter stature, fewer leaflets ((1–) 3–7) and rays (5–8), the leaflet margin white-ciliate. The new species, which is assessed as Critically Endangered (CR), was only found on limestone cliffs. We also provide a new key to the species of Pternopetalum.

Aiphanes argos is a new species of palm segregated from Aiphanes parvifolia, which is now recognized to be a species complex. Aiphanes argos is one of the few rheophytic members of the palm family, and is endemic to a small area in the Samaná Norte River canyon in Antioquia, Colombia, where it is critically endangered because its populations are threatened by the damming of the river for a hydroelectric plant. The epiteth argos is the name of the conglomerate that intends to build the dam, and is given to the palm as a plea for the conservation of the Samaná Norte River canyon.

A new species of the genus Dictyanthus is herein described and illustrated, more than 30 years since the last paper describing new species of this genus. Dictyanthus stevensii sp. nov. is known only from the Zoque forest in the Chimalapas region in the state of Oaxaca, Mexico. This species differs from all other species because it has the smallest flowers within the genus. It is morphologically related to D. eximius, a microendemic species of Chiapas. Information on the distribution and habitat of this new species is given, and its conservation status is proposed as Critically Endangered B2ab(ii). An identification key to Dictyanthus species in southern and southerneast Mexico is also provided.

We describe and illustrate Wahlenbergia itatiaiensis, a new species of Campanulaceae, endemic to the Itatiaia National Park in the Atlantic Forest (Brazil). The new species is compared with W. linarioides, the sympatric and morphologically most similar species, and to W. intermedia. Wahlenbergia itatiaiensis is mainly distinguished by the linear to lanceolate leaves with few, short denticles along the margin, 3-locular ovary, and 3-lobed stigma. An identification key for these species is provided. The new species occurs on sandy and rocky, wet soils, adjacent to dirt roadsides of the upper part of the National Park. Detailed comments on the distribution and conservation status, as well as details of morphological variation and photographs are provided.

We describe and illustrate Paepalanthus capixaba, a new species of Paepalanthus ser. Paepalanthus. The species is endemic to Espírito Santo state and restricted to a very distinct and endangered area, which comprises a mosaic of quartzitic sandy patches within a granitic argillaceous site. The indument of leaves, spathes, and scapes is crucial to recognize the taxon as a unique entity. The species is compared to Paepalanthus klotzschianus, the morphologically most similar species. An official conservation status of critically endangered species was assessed by the Centro Nacional de Conservação da Flora committee. Comments on the occurrence area and the morphological variation of the species, as well as a distribution map, photos, and illustrations are provided.
