A New Species

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.

A New Species

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.

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.

A New Species

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.

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.

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.

Abstract—Justicia rubrobracteata, a new species from northeastern Brazil, is described and illustrated. The new species is morphologically similar to J. aequilabris due to its shrubby habit, and terminal and axillary spicate inflorescences with red flowers. However, J. rubrobracteata is differentiated mainly by the shape and color of its bracts and bracteoles as well as an orangish macula in the corolla, and a torulose capsule. In addition, J. rubrobracteata is only known from northeastern Brazil, from the states of Paraíba and Rio Grande do Norte, while J. aequilabris is widely distributed in Bolivia, Brazil, and Paraguay. A table with the main morphological characters of both species is included, as well as photographs, a key to species of Justicia for the states of Paraíba and Rio Grande do Norte in northeastern Brazil, a distribution map of both species, and conservation data for the new species.
