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).

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.

AbstractLotus sanguineus is one of the endemic taxa from Mediterranean Region of Turkey. It has hitherto been known from type locality and was assessed under VU and EN categories despite the lack of information on the population size, number of location and habitat quality. This study aims to determine the global conservation status and conservation strategies of the narrow endemic species. We collected all available data and evaluated them with the field studies. We reported the sizes of populations, altitude, coordinates, habitat types and the threats it faces for each locality. GeoCAT analyses at global levels indicate the extent of occurrence 19.965 km2 and area of occupancy 9 km2 and there could be an inferred decline due to habitat loss and fragmentation of the original population, suggesting this species might be classified as Critically Endangered, based on criterium B1ab (i, ii, iii) + 2ab (i, ii, iii) in the Red List categorization. Conservation priorities include life history and ecology studies, in-situ conservation, population monitoring and ex-situ conservation to prevent the destruction of the existing gene pool.

Macrosamanea macrocalyx is an endemic species from the state of Pará in Brazil. It was described based on specimens collected by A. Ducke in 1916 and J.G. Kuhlmann in 1924, in the municipality of Altamira. Since then, the species has not been recorded. The construction of the Belo Monte hydroelectric dam on the Xingu River permanently flooded a large area in this region. We report the rediscovery of M. macrocalyx in its natural habitat, and provide new taxonomic information, particularly the first description of the mature fruits and seeds. We evaluate its conservation status as critically endangered (CR), based on current knowledge and the IUCN criteria.

A new species of Lagenandra (Araceae), is described and illustrated from Walauwewaththa Wathurana freshwater swamp forest, Bulathsinghala, Sri Lanka. Here we describe the new species as Lagenandra wayambae Madola, K. Yakandawala, D. Yakandawala and Karunaratne and provide a detailed description, drawing and colour photographs. We compare the morphology of L. wayambae with that of similar members of Lagenandra and conduct an assessment of its conservation status. A taxonomic key to the Sri Lankan Lagenandra is presented for easy identification. Recognizing a new endemic member enhances the number of Sri Lankan species to nine. According to the IUCN red data category guidelines L. wayambae qualifies for Critically Endangered category under Criterion B1ab (ii,iii,v) + B2ab (ii,iii,v).

Cyanea heluensis H. Oppenheimer, sp. nov., a new, narrowly distributed endemic species, is herein described and illustrated with line drawings and digital field photos. It is currently known from a single mature plant and is restricted to the upper Helu planeze on leeward Mauna Kahalawai, West Maui, Hawaiian Islands. It differs from all other species of Cyanea Gaudich. with its narrow, shallowly lobed leaves, gently curved muricate corollas, and undulate sepals caducous in fruit. A key to the new species and its congeners on Mauna Kahalawai is provided. Its conservation status and efforts to propagate the species are discussed.

Tripleurospermum heterolepis (? Chamaemelum heterolepis), whose specimens are referred to as syntypes, is a narrow Turkish endemic species assessed as Critically Endangered according to the IUCN categories. Tripleurospermum tempskyanum (? Chamaemelum tempskyanum) is known as endemic to Greece, but is also distributed in Turkey. In this study, the name C. heterolepis is lectotypified on a specimen deposited at LD. Additionally, a description of T. tempskyanum in the Turkish flora is presented, and its conservation status is indicated. The diagnostic morphological characters which distinguish T. tempskyanum from its close relatives are discussed.

In 1890, Salvia freyniana Bornm., an endemic species of Turkey, was first collected and described by J.F. Bornmueller in 1892. While revising the genus occurring in Turkey based on specimens collected from Yenipazar, south of Yozgat (Turkey in 1892), it was discovered once again in 2006. The diagnostic morphological characters of this rare endemic species are discussed. Details of fruiting material and pollen micromorphology are given for the first time. Moreover, an emended and expanded description, distribution, phenology and ecology of this species are also provided along with its conservation status. Key words: Salvia freyniana Bornm.; Lamiaceae; Endangered; Rediscovery; Turkey

The Trigonidiinae crickets of Rodrigues are examined. Two species widespread in South Western Indian Ocean islandsare recorded in Rodrigues for the first time: Trigonidium cicindeloides Rambur, 1839 and Natula longipennis (Serville,1839). Nemobius luteolus Butler, 1876 is a Trigonidiinae and not a Nemobiinae, it is transferred to Metioche Stål, 1877 asMetioche luteolus (Butler, 1876), n. comb. Two new species are described from the restored areas of the island. Thesenew species are tentatively considered as Metioche and included in the new subgenus Superstes n. subgen.: Metioche (Su-perstes) superbus n. subgen., n. sp. and Metioche (Superstes) payendeei n. subgen., n. sp. This new subgenus is charac-terized by the male genitalia asymmetry and the striking hyperthely of the left pseudepiphallic lophi and paramere. Elements of the ecology of endemic Trigonidiinae of Rodrigues are given, and their conservation status is assessed.
