Schinus pampeana is a new species from Brazilian Pampa. The new species was tentatively included in Schinus sect. Terebinthifolia, and is morphologically most similar to Schinus lentiscifolia and S. weinmanniifolia. We present here a detailed morphological description, a geographical distribution map, IUCN conservation status assessment, ecological data, photographs, and a table of diagnostic characters of S. pampeana and the most similar species. Schinus pampeana increases the total number of Schinus to about 49 species, of which eleven are recorded in Brazil.

A New Species

The Brazilian savanna (Cerrado domain), although without significant richness of Chrysobalanaceae, has widely distributed species of this family, and some endemic to this domain. Couepia, a Neotropical genus, includes 62 species distributed mainly in lowland tropical forests with three species recognized for the Brazilian savanna. Here we report a new species of Couepia endemic to Brazilian savanna in the region with the greatest agricultural advance in Brazil, from the states of Tocantins and Goiás. We provide a description, a distribution map, photographs, a preliminary conservation status assessment and comparisons with other species of the genus that occur in this domain. With this addition we help to contribute to the knowledge of plant biodiversity, which is an urgent and fundamental step towards planning and carrying out conservation actions.

Bellevalia behcetii (Asparagaceae) is described and illustrated as a new species from Şırnak province in South Eastern Anatolia (Turkey). It is morphologically similar to B. paradoxa but easily differs in several morphological characters. Diagnostic morphological characters, a full description and detailed illustrations of the new species are provided. A quantitative morphometric analysis was carried out to check the diagnostic characters of Bellevalia behcetii with respect to morphologically related species. The somatic chromosome number was determined as 2n = 2x = 8 in B. behcetii. In addition, the ecology and phenology of the new species, as well as its etymology and the pollen characteristics, are presented and discussed. The conservation status of B. behcetii was assessed according to IUCN protocol. A distribution map of B. behcetii and related species is also presented.

A New Species

Polystachya orophila, a new species of Orchidaceae, is described based on specimens collected during the baseline study of the Guinean Nimba Mountains for the environmental impact assessment for a proposed mining project. While material belonging to this species was mentioned as early as 1920 by Chevalier, it has historically been confused with P. microbambusa, from which it differs by its typically Polystachya-like clustered pseudobulbs, placing it in P. sect. Polystachya, whereas P. microbambusa has pseudobulbs successively growing on top of one another, forming developed and persistent stems, and is the sole representative of P. sect. Dimorphocaules. The complex taxonomic and nomenclatural history of P. microbambusa is also clarified. For both taxa we provide a morphological description as well as information on distribution, habitat, and phenology, an IUCN conservation status assessment using the Red List criteria, and a distribution map, along with a dichotomous key that also includes the most similar members of P. sect. Polystachya.

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

Pariana caxiuanensis (Poaceae) is described and illustrated as a new species from the Brazilian Amazon. The new species is characterized by having the leaves clustered at the apex of the leafy culm, fimbriae few to absent, dimorphic flowering culms, large ligules (2.5–4 mm long), and pubescent to hirsute synflorescences. We present a morphological description, illustrations of the new species, the conservation status assessment, and a key to differentiate P. caxiuanensis from its morphologically related congeners.

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.
