SummaryWe revise and update the records of strict and near-endemic species of Mt Kupe, Cameroon respectively from 31 strict endemics in 2004, to 25 today, and with near-endemic species 30, unchanged in number but with turnover. The changes result from new collections, discoveries and taxonomic changes in the last 16 years. While 15 of the provisionally named putative endemic species have now been formally published, a further 18 have not. The majority of the 30 near-endemic species (18) are shared with the adjacent Bakossi Mts, far exceeding the numbers shared with the more distant Mt Etinde-Mt Cameroon, Rumpi Hills and Ebo forest areas (sharing three near-endemic species each with Mt Kupe). We test the hypothesis that a further one of the provisionally named putative Mt Kupe species, Vepris sp. 1 from submontane forest near the summit, is indeed new to science. We compare it morphologically with the two other bicarpellate high altitude Cameroon Highland tree species V. montisbambutensis Onana and V. bali Cheek, concluding that it is a new undescribed species here named as Vepris zapfackii. The new species is illustrated and its conservation status assessed as Critically Endangered using the 2012 IUCN standard, due to habitat clearance from agricultural pressures at its sole location which is unprotected. Vepris zapfackii and V. bali appear unique in African trifoliolate species of the genus in having opposite leaves. Vepris zapfackii differs in having hairy petiolules and midribs and petiolules with the blade decurrent distally, narrowing towards a winged-canaliculate base (vs glabrous and petiolule long, terete), and sparsely golden hairy pistillodes and a glabrous calyx (vs densely black hairy pistillodes, and sepals hairy).

Endemic species on mountains often have narrow altitudinal ranges and are more threatened at the higher altitudes, especially with climate changes. However, plants could use special microhabitats at the mountain tops as proper places for surviving the climate change (i.e., refugia). We assessed population attributes of three critically endangered endemic species (Primula boveana Decne ex Duby, Rosa arabica Crep., and Silene leucophylla Boiss.) in two growing seasons (2006/2007 and 2013/2014), differing in the received rainfalls in microhabitats at the high mountains of southern Sinai. Both P. boveana and S. leucophylla had very small population size, but significantly increased in the 2013/2014 growing season which received above average rainfalls. The population of R. arabica is the smallest (around 40 individuals) and did not increase, even after the increase in rainfalls. Whereas P. boveana is present in fewer sites and grew in small number of specific microhabitats, both S. leucophylla and R. arabica were recorded in most studied sites and habitat types. Unlike R. arabica, both P. boveana and S. leucophylla were recorded in caves and steep slopes and on the top of the mountains. This indicates that these sheltered mist microhabitats are the best for future conservation of these species after climate change.

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.

We describe here Bertolonia lucernula, a new endemic species from the state of Espírito Santo, Brazil. It is only known from one locality, the “Área de Proteção Ambiental Mestre Álvaro”, in the municipality of Serra. The new species can be recognized by the branches and petioles covered with sessile and short-stalked glands and scattered unbranched trichomes, flat leaf blade surfaces covered only with sessile and short-stalked glands, small flowers with a widely campanulate hypanthium covered with the same trichomes as the petioles, calyx with membranaceous, truncate sepals, and short, triangular external teeth, asymmetric and obovate petals, with the apex covered with sessile and short-stalked glands on the adaxial surface. According to IUCN criteria, Bertolonia lucernula should be classified as Critically Endangered (CR).

A new species of Calliandra (Leguminosae, Mimosoideae, tribe Ingeae) from a restricted locality of Campeche, Mexico is herein described and illustrated. The species appears to be closely related to C. molinae, a species from Honduras, El Salvador and Nicaragua, from which it may be distinguished by being allopatric, and by a more limited development of suberose bark in stems and branches, comparatively smaller leaflets, consistently glabrous leaflets and corollas, and by the scarcely villous pods. Calliandra mayana appears to be restricted to an extremely small seasonally flooded savannah surrounded by tropical deciduous forest and, based on IUCN criteria, it is provisionally considered Critically endangered.

A new endemic species, Nepenthes cabanae, belonging to sect. Insignes is described from the Mt. Pantaron range of central Mindanao. The species is assessed as Critically Endangered. This discovery brings the number of Nepenthes species in this mountain range to eight. Mt. Pantaron is currently not a protected area, but the diversity of Nepenthes taxa suggests concerted efforts should be made to develop a conservation strategy to preserve and protect the area.

A new species of Calceolaria endemic to central Chile is described. A comparison with morphologically similar species is made, and a key as well as detailed images to differentiate them is provided. The species is only known from the Natural Sanctuary Cerro El Roble, which is part of the coastal mountain range of central Chile and can be considered as  Critically Endangered (CR) under the IUCN categories and criteria.

<p>A new name in the genus <em>Ledebouria</em> Roth is validated for <em>Scilla viridis</em> Blatter &amp; Hallberg [non <em>Scilla viridis </em>(L.) Salisbury].  It is rediscovered after about 85 years of its first and only report.  It is also redescribed on the basis of morphology, anatomy, cytology and assigned the name <em>Ledebouria junnarensis </em>S.S. Rahangdale &amp; S.R. Rahangdale belonging to the family Asparagaceae, subfamily Hyacinthoideae.  As this is a species endemic to the Western Ghats, Maharashtra, India, it is studied for threat status as per IUCN criteria &amp; guidelines and assigned the status Critically Endangered B1ab(iii)+2ab(iii).  Identification keys for the genera and species of subfamily Hyacinthoideae reported from India are prepared on the basis of reported and observed characters.</p><div> </div>
