A new species of Schwenckia (Solanaceae) from calcareous outcrops of the Serra Azul Biological Reserve in northern Minas Gerais, Brazil, is described and illustrated. Schwenckia aurantiaca is an annual plant characterized by a cylindrical corolla tube with five orange, linear appendages, an androecium with two stamens and three, unequal pilose staminodes, and a calyx that tears to the base in fruit. We discuss the morphological characters, habitat, and conservation status of the species, which is assessed as Critically Endangered.

A New Species

Colanthelia is a woody bamboo genus belonging to the Arthrostylidiinae and currently includes nine species. It can be recognized by a suite of morphological characters including hollow and thick-walled culms, branch complement with a promontory in the base and a dominant divergent branch bearing few to many secondary small branchlets from its base, culm leaves with a relatively well developed girdle and a crest or skirt at the juncture of the sheath and girdle, racemose or weakly paniculate synflorescences, and relatively long and narrow spikelets with visible rachilla internodes. During recent fieldwork in Minas Gerais state, a new species, Colanthelia longipetiolata, from the Brazilian Atlantic forest was collected, which is here described and illustrated. So far as we know, the species is endemic to the Caparaó National Park, in Minas Gerais state. Comments on its habitat, distribution and conservation status, a morphological comparison between C. longipetiolata and C. sparsiflora, and a revised identification key to all species of the genus are provided.

Silene lulakabadensis Heidari, F. Ghahrem. & Assadi is described as a new species from Zanjan Province, Iran. The new species is a dark green plant, perennial and woody at the base, that was collected on marl soil slopes at 2100 m. It is believed to be closely related to S. eriocalycina Boiss. from section Auriculatae (Boiss.) Schischk. but is a smaller plant, with much shorter internodes, and pinkish-white retuse to emarginate petals with very small or no scales. It is a very rare plant and its conservation status is assessed as Critically Endangered.

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).

A New Species

Background and Aims: Cochemiea is a genus which currently comprises five species occurring in Mexico. It is morphologically characterized by cylindrical decumbent to prostrate stems and by a long red-scarlet zygomorphic perianth, presumably specialized for hummingbird pollination. As part ofthe ongoing taxonomic studies on the North Mexican flora, a population discovered by Thomas Linzen in 2012 in central Sinaloa (Mexico), previously identified as Mammillaria sp., actually refers to a Cochemiea species and cannot be ascribed to any of the known species of that genus. As a consequence,we here propose to describe this population as a a new species for science.Methods: The work is based on field surveys (autumn 2018 and spring 2019) in central Sinaloa, examination of herbarium specimens, and analysis of relevant literature. Its conservation status was assessed following the guidelines of the IUCN; AOO and EOO were calculated with the programGeoCAT.Key results: Cochemiea thomasii is described and illustrated from Sinaloa. The new species is morphologically similar to C. halei from which it differs by the hanging stems, the larger conical tubercles, less numerous and shorter central spines, and the ovoid fruits. A diagnostic key of the knownCochemiea species is included.Conclusions: Cochemiea thomasii is endemic to the state of Sinaloa where it occupies a small area. On the basis of the criteria B2a (geographic range) and C (small population) of IUCN, the new species can be assessed as Critically Endangered (CR) or Vulnerable (VU). Adopting the precautionary approach, Cochemiea thomasii is considered as Critically Endangered (CR).

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.
