Extensive field surveys of the Critically Endangered Central and Eastern Rûens Shale Renosterveld have uncovered that Notobubon striatum, as currently circumscribed, comprises two distinct species. Upon careful examination of the type material it has become clear that names exist for both species. The type specimen of N. striatum clearly matches the lesser known species, a large shrub, ca. 1 m. tall, with a powerful anise-scent and which is restricted to the banks of seasonal rivers and watercourses in the Central and Eastern Rûens Shale Renosterveld. The second and better known entity, with a wider distribution, corresponds to the type material of Dregea collina Ecklon & Zeyher. As such, a new combination, Notobubon collinum (Ecklon & Zeyher) Magee, is here made to accommodate this taxon, restricted to dry quartz and silcrete patches or outcrops in Eastern Rûens Shale Renosterveld. In their revised circumscriptions N. striatum and N. collinum are readily distinguished by habit, scent, leaf size and division, as well as leaf lobe shape and sepal size. Comprehensive descriptions of both species are provided, together with notes on their ecology and conservation status, and the existing key to the species of Notobubon updated. This brings the number of recognised species in the genus to thirteen.

Populations of harlequin frogs Atelopus are declining throughout their geographical range. In Peru six of the 11 nominally described species are Critically Endangered, and there are at least 17 undescribed additional forms (all representing apparently distinct species), the conservation status of which is unknown. Most Atelopus taxa in Peru have relatively small geographical ranges, some known only from single populations, and have only a limited chance of survival. Conservation will require: (1) improvement of the faunistic and taxonomic knowledge of the genus, (2) field surveys, including in remote areas, (3) assessment of all species and populations for chytridiomycosis and research on the agent's biology, (4) ex situ conservation measures to facilitate later reintroduction, and (5) involvement of national and international conservationists and local people.

Caudatella columbiella(McDunnough, 1935), new combination, (Insecta: Ephemeroptera: Ephemerellidae) is removed from synonymy withCaudatella heterocaudata(McDunnough, 1929), and a new junior synonym is recognized, based on comparative examination of type material and larval exuviae associated with adults from the type locale ofC. columbiella(=C. californica(Allen and Edmunds, 1961), new status, new synonym).Caudatella circia(Allen and Edmunds, 1961), new status, is recognized as a strict specific synonym ofC. heterocaudata(McDunnough, 1929) (=C. circia(Allen and Edmunds, 1961), new synonym). A neotype is designated forCaudatella hystrix(Traver, 1934), based on a specimen collected in Western Montana, USA, during June 2000. Morphological differences between the type specimen ofC. hystrixand the type specimens of its two junior synonyms,Ephemerella cascadiaAllen and Edmunds, 1961, andE. spinosaMayo, 1952, are detailed. An identification key for larvae of the genusCaudatellais included.

Through extensive field work and careful examination of specimens, live plant photos, and related publications of Aristolochia, we conclude that A. austroyunnanensis and A. dabieshanensis are distinct species. Meanwhile, Aristolochia hyperxantha, a new species from northwestern Zhejiang, China, is described and illustrated. The new species is similar to A. mollissima in the flower color, but it differs in the indumentum and shape of leaf. Aristolochia hyperxantha is also similar to A. dabieshanensis in the leaf shape, but it differs in the shape and color of flower.

Padre Island is the world’s longest barrier island and includes the longest stretch of undeveloped barrier island in the world. Largely due to harsh environmental conditions and difficult access, only cursory and incomplete checklists and subjective estimates of abundance have been produced. The results of an inventory of amphibians and reptiles of North Padre Island conducted 2002–2020, including the results of extensive field surveys conducted 2002–2003, are reported herein. Natural history museum and iNaturalist records are summarized and compared among North and South Padre and Mustang islands and the mainland portion of the seven counties in which the islands occur. The conservation status of rare species and extirpation of others is noted. The morphology and taxonomic status of some unique occurrences are discussed. Eleven species of amphibians and 39 species of reptiles presently occur or have occurred naturally or as introduced or accidental species on North Padre Island. Twelve species of amphibians and 50 species of reptiles occur or have occurred on North Padre, South Padre, and Mustang islands. Thirty-one species of amphibians and 93 species of reptiles have been reported from the seven counties in which the islands occur.

In the context of producing a revised phylogenetic Linnean taxonomy of angraecoid orchids, the monotypic and narrow-endemic genus Ossiculum is synonymised with Calyptrochilum. Accordingly, a new combination in Calyptrochilum is proposed for Ossiculumaurantiacum. The morphological and DNA-based evidence for this transfer is discussed. Moreover, Calyptrochilumaurantiacum is here firstly reported outside Cameroon, with a record from the Republic of the Congo. The Red List conservation status of this species is reassessed and it is to be downgraded from “Critically Endangered” (CR) to “Endangered” (EN), following the recent discovery of additional subpopulations in Cameroon.

Background: The correct author citation of Oxalis sonderiana (Kuntze) J.F.Macbr. and the validity and identity of the species Oxalis beneprotecta R.Knuth, Oxalis bullulata T.M.Salter and Oxalis pulchella Jacq. var. beneprotecta (R.Knuth) T.M.Salter are unclear.Objectives: To resolve the nomenclatural and taxonomic confusion surrounding these four taxa.Method: We studied relevant herbarium records (especially type material) of all the taxa, and paired this with scrutiny of all publications that bear reference to the nomenclature and taxonomy of these species.Results: The correct author citation for Oxalis sonderiana has been determined; Oxalis bullulata is confirmed as a distinct species, and the continued recognition of Oxalis beneprotecta as a variety of Oxalis pulchella is suggested. It is further ascertained that the name ‘Oxalis nidulans Turcz.’ is not a later homonym, but a reference to a misapplication of Oxalis nidulans Eckl. Zeyh. to the type specimen of Oxalis sonderiana.Conclusion: These results clarify the current confusion surrounding these taxa in global herbaria and in national and international databases.

A new species of Magnolia from the southern Sierra Madre Oriental, Mexico, is described and illustrated, providing information about its habitat distribution, ecology, biogeography and conservation status. After 12 fieldwork expeditions near the border of the states of Hidalgo and Puebla, we have developed morphological, ecological and biogeographic data to support recognition of populations from Acaxochitlán, Hidalgo and Pahuatlán, Puebla as a distinct species of Magnolia sect. Macrophylla. A key to species of this section and a distribution map for Mexican taxa are provided. The species was assessed as critically endangered (CR).

Abstract—Two new species of Turnera (Passifloraceae s. l., Turneroideae), T. acangatinga and T. ibateguara, from the Atlantic Forest of northeastern Brazil, are described. Some specimens of T. acangatinga were originally treated as T. annularis. Turnera ibateguara was recently considered part of T. pernambucensis, a species which also occurs in the Atlantic Forest in northeastern Brazil, and which was, until then, only known from the type material. In this study, recent collections of T. pernambucensis in the state of Alagoas revealed that both are distinct species and that have been mistakenly identified so far. We provide data on morphology, distribution, habitat, and phenophases, a preliminary conservation status assessment for the three species, and a key to the species with capitate inflorescences from Alagoas and Pernambuco.

AbstractWenchengia alternifolia (Lamiaceae) is a plant species endemic to Hainan Island, China. Since the 1930s it was known from only four collections and was believed to be extinct until a remnant population was rediscovered in 2010. We conducted further field surveys during 2010–2012 but located only one population, with 66 individuals. W. alternifolia is restricted to the c. 1,500 m2 Shuangximu Valley, in a harsh microenvironment surrounded by plantations. As the population comprises < 50 mature individuals, we propose that W. alternifolia be categorized as Critically Endangered on the IUCN Red List, based on criterion D. We recommend that the remnant population and its habitat need urgent protection and monitoring and that ex situ conservation, for future reintroduction, should be implemented.
