Passiflora danielii, an endemic species to Colombia, which is threatened, was rediscovered in the Department of Antioquia, where it has not been reported since 1938. The species was only known from the type locality (Municipality of Cocorná). Now, four new locations are added near it. The current study further presents a revised morphological description of P. danielii based on fresh material, along with an updated distribution map. Finally, following the IUCN Red List Criteria, P. danielii was classified as Critically Endangered (CR) species.

Parahyparrhenia bellariensis, an extremely rare and highly narrow endemic grass, has been rediscovered after almost 184 years from Cuddapah [Kadapa] district, Andhra Pradesh. The first description of its complete habit, basal portion and other features of the spikelets are provided along with new locality of its occurrence. In addition, photographs of the habitats, live plants, and a key to distinguish two Indian endemic species, distribution map and illustration are provided. As per the IUCN Red List Criteria this species is assessed here as Critically Endangered (CR). In order to facilitate the prospective conservation of this grass, we have discussed about the peculiarity of its habitat.

Two new micro-endemic species of Eriocaulaceae are described from the Campos Rupestres of Serra Nova State Park, a conservation unit located in the Espinhaço Range in northern Minas Gerais state, Brazil. Herein we provide descriptions, illustrations, photographs and maps, together with notes on morphology, distribution, phenology, taxonomy, and conservation. Paepalanthus ferrugineus is distinguished mainly by the reddish-brown involucral bracts, surpassing the floral disc, with the apex attenuate and tufted adaxially, tufted sepals and hairy petals. Syngonanthus polyaxis is easily differentiated by the inflorescence architecture with three morphologically distinct axial parts. Both species are considered Critically Endangered according to the IUCN Red List criteria.

AbstractThe plant Mollinedia stenophylla Perkins (Monimiaceae) is endemic to southern Brazil and, until 2015, had not been seen for 122 years. We located a single population of the species on the margin of a watercourse in the mountainous region of Rio de Janeiro state. We describe the location of the species, comment on its morphology, ecology and conservation, assess its conservation status, propose conservation measures, and discuss the potential value of local action plans for this and other narrow endemic plant species. Mollinedia stenophylla has whorled leaves, clonal reproduction and a low height, unusual traits in the genus Mollinedia. Using the IUCN Red List criteria we assess the species as Critically Endangered. This example highlights the importance of investing time in plant surveys and taxonomy, especially in megadiverse countries such as Brazil.

Despite having been first published in 1941, Carya poilanei (Chev.) Leroy is only known from two original collections in Vietnam and Laos; however, it has not been recollected since then and long suspected to be extinct by repeated deforestation events. Here, we report the rediscovery, and meanwhile the first new record in China, of this extremely rare gigantic hickory species at Yunnan province after 80 years. Three small patchy subpopulations were found with a total of about 50 adult trees have diameter at breast height (DBH) larger than 60 cm, together with some seedlings and saplings, but the fruit set was low. Based on multiple fresh materials, we present a revised morphological description of C. poilanei, and an updated distribution map for the species. In addition, we also provided a key for the hickories in China. Lastly, we suggest C. poilanei should be listed as Critically Endangered (CR) or Endangered (EN) species according to the latest IUCN Red List Categories and Criteria.

It has not been recollected since then and was long suspected to have become extinct through repeated deforestation events.

Based on new and fresh material, we present a revised morphological description of C. poilanei, and an updated distribution map for the species. In addition, we also provide a key for the hickories in China. Lastly, we suggest C. poilanei should be listed as a Critically Endangered (CR) species according to the latest IUCN Red List Categories and Criteria.

A New Species

A new Begonia species, Begonia makuruyot, from B. section Baryandra is described and illustrated from forests over limestone in Surigao del Norte. This distinctive species, which appears to be endemic to the type locality, inhabits shaded limestone walls along the Daywan River at an elevation of 10–50 metres above sea level. Begonia makuruyot is distinguished from other Philippine Begonia by its rugose laminae, pendent leaves, pilose petioles and stipules fused with fleshy, aristate trichomes that are occasionally branching. A comparison with the phenetically similar B. acuminatissima is provided. Based on IUCN Red List criteria, B. makuruyot is designated Critically Endangered (CR).

First Time

Ceropegia rudatisii Schlechter was first collected in KwaZulu-Natal, South Africa in 1903 but described in 1905 based on a second independent collection. This Ceropegia species was not seen again for a century and believed to be extinct. In 2020, however, two very small populations were discovered not far from the type locality. The subsequent examination of living flowering plants allowed an updated morphological description and, for the first time, illustration of C. rudatisii with photographs of living flowering plants and details thereof. We provide a comprehensive species description including novel aspects and details, i.e. bracts, inner corolla colouration, pollinarium and pollinia, as well as posture of corolla lobe tips of fresh flowers in situ—being not suberect-spreading, as given in earlier treatments, but flaccid-pendulous. The conservation status of C. rudatisii according to IUCN Red List criteria is furthermore discussed. Conservation measures are indispensable and urgent to avoid the extinction of C. rudatisii.

A New Species

Flueggea acicularis (Phyllanthaceae) is endemic to the karst region of central China. Male specimens of this species were first collected in 1908. In 1989, female plants of F. acicularis were found for the first time, but misidentified as a new species. Throughout this period the male plants of F. acicularis were mismatched with female plants of other species, and male plants had not been collected since 1908. Then, in March, 2009, the authors rediscovered a wild population of F. acicularis consisting of both male and female plants in Wuxi county, Chongqing municipality, China. Based on field investigation and examination of specimens, we matched the correct female and male plants of this species for the first time since its initial publication a century ago. A complete and accurate morphological description, distribution, habitat and phenology of this species are also provided. Furthermore, the conservation status of F. acicularis is assessed as “Near Threatened” (NT) according to the IUCN Red List criteria.
