The Impact

Climate change is an important driver of biodiversity loss and extinction of endemic montane species. In China, three endemic Juniperus spp. (Juniperuspingii var. pingii, J.tibetica, and J.komarovii) are threatened and subjected to the risk of extinction. This study aimed to predict the potential distribution of these three Juniperus species under climate change and dispersal scenarios, to identify critical drivers explaining their potential distributions, to assess the extinction risk by estimating the loss percentage in their area of occupancy (AOO), and to identify priority areas for their conservation in China. We used ensemble modeling to evaluate the impact of climate change and project AOO. Our results revealed that the projected AOOs followed a similar trend in the three Juniperus species, which predicted an entire loss of their suitable habitats under both climate and dispersal scenarios. Temperature annual range and isothermality were the most critical key variables explaining the potential distribution of these three Juniperus species; they contribute by 16–56.1% and 20.4–38.3%, respectively. Accounting for the use of different thresholds provides a balanced approach for species distribution models’ applications in conservation assessment when the goal is to assess potential climatic suitability in new geographical areas. Therefore, south Sichuan and north Yunnan could be considered important priority conservation areas for in situ conservation and search for unknown populations of these three Juniperus species.

A New Species

A new species, Muscari inundatum (Asparagaceae) from Turkey, is described and illustrated. It is morphologically similar to M. neglectum and M. adilii, but differs mainly by its shouldered fertile flowers with erect to slightly recurved lobes at maturity. In this study, a comprehensive description, diagnostic characters, original photographs, detailed illustration, geographical distribution, conservation assessment, identification key, and taxonomic comments on the new species are presented.

Lanceolate Leaf

Miconia rheophytica is described, illustrated, and compared with presumed relatives in the Octopleura clade. It is distinguished by its narrowly elliptic to ovate-lanceolate leaf blades with entire to subentire margins that have evenly spaced spreading smooth eglandular trichomes 0.8−1.4 mm long, an indumentum of dendritic trichomes with short axes and terete radiating arms on distal internodes, adaxial petiole surfaces, and primary and secondary veins on abaxial leaf surfaces, unribbed hypanthia that are constricted and tapered distally below the torus and covered with a mixture of basally roughened trichomes and dendritic trichomes with short axes, anthers with two ± truncate apical pores, eglandular anther appendages, 3-locular ovary, and berries that are bright blue at maturity. It is known only from flash-flooded riverbanks in three river canyons in the Magdalena Medio region of Antioquia, Colombia. A conservation assessment of “Endangered” is recommended for this species based on IUCN Red List Categories and Criteria.

A New Species

Taxonomic issues regarding three species of Styrax ser. Valvatae in Brazil are addressed. Styrax bahiensis, a new species from Bahia state, northeastern Brazil, is described and illustrated. It is similar to S. pallidus in its leaves of similar size and anther thecae that exceed the connective, but differs by coriaceous leaf blades with a revolute margin, leaf domatia up to 0.7 mm long and flat or rarely slightly bulging, a yellow- or orange-stellate-tomentulose calyx abaxially, and spreading corolla lobes. The species is known only from the type collection gathered over 50 years ago. Styrax griseus is placed in synonymy under S. kuhlmannii, a species from central Brazil, and a lectotype is provided for S. kuhlmannii. An updated description and estimate of the geographic distribution of S. pauciflorus are provided, as well as a lectotype and conservation assessment for this species.
