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.

Tripleurospermum heterolepis (Freyn & Sintenis) Bornmüller has been poorly known as a local endemic species classified within DD category of IUCN. It had not been collected since its introduction to scientific community in 1895. In 2007, T. heterolepis was rediscovered in its type locality. Based on its syntypes deposited at B and G as well as the new specimens collected from the type locality, a misdescription of the species in the Flora of Turkey and the East Aegean Islands is also reported. A new description of T. heterolepis, amended and extended, is presented here, and its updated conservation status is indicated. The diagnostic morphological characters that distinguish the species 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.

Endemic Plant Species

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.

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.

Delphinium fissum subsp. sordidum has been found in calcareous and schistaceous slopes on the Mines of Santo Adrião, Trás-os-Montes region —close to Bragança, northeastern Portugal—. It is the first record of this taxon in Portugal and the westernmost locality of its general distribution area. Its conservation status, according to the most recent IUCN categories and criteria, should be “Critically Endangered” in Portugal.

In the course of the writing of the Flore de la Nouvelle-Calédonie treatment for Asclepiadoideae, Periplocoideae and Secamonoideae, several new species have already arisen partly due to more intensive field work and to a renewed interest in this group of plants. In December 2018, another striking and unorthodox new species was spotted and collected on the flanks of the Kopéto massif mining site. Because this new species has morphological characters from three genera (Dischidia, Gymnema and Marsdenia), further studies, especially molecular, were needed to assess its relationships. These studies show it as a member of one of the New Caledonian Marsdenia subclades. We herein propose to describe it as Marsdenia goromotoorum Gâteblé, Fleurot, Meve & Liede, the only species of Marsdenia in New Caledonia lacking both corolline and gynostegial coronas. It is a micro-endemic species with pinkish-red tubular flowers, growing on serpentines and known from only eight plants. Due to the anthropogenic fire threat, we propose to consider it as Critically Endangered.

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.

Reseda balansae Müll. Arg. (Resedaceae) is a very restricted and endangered Turkish endemic species known only from Mersin province (South Turkey), in a hotspot of biodiversity. It was first collected in 1855, and subsequently described in 1857. Afterwards, it was only collected once again in 1896. In this study we report the rediscovery of these two populations of R. balansae in Turkey more than 120 years after its last known collection. We provide a detailed revised description of this poorly known species and comments about its taxonomy (including designation of a lectotype), distribution and ecology. We also perform the first conservation assessment of the species at a global scale under IUCN categories and criteria, resulting in the proposal of the critically endangered category for the species, which apparently persists in one single population, since the type population has recently been destroyed.
