This change in status is supported by eight newly elucidated, qualitative, morphological, diagnostic characters despite the overall similarity with A. winkleri, a species restricted to Cameroon and Gabon. Afrothismia ugandensis is remarkable in the genus for occurring in semi-deciduous (not evergreen) forest and for having ellipsoid or ovoid (vs globose) root bulbils. It has only been recorded twice, first in August 1940, and most recently in June 1998, despite targeted searches in recent years. In both 1940 and 1998, only single individuals appear to have been detected. A single site for the species is known with certainty. It is here assessed as Critically Endangered [CR B2ab(iii); D1] using the IUCN categories and criteria. A. ugandensis is threatened by forest degradation and clearance due to illegal, selective, small-holder logging for firewood and charcoal, timber and limited agriculture.","PeriodicalId":51321,"journal":{"name":"Kew Bulletin","volume":"382 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142198841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a new species of Ceratozamia (Zamiaceae, Cycadales) from the southeast of Mexico is described and illustrated. It was previously misidentified as C. subroseophylla because of the lack of reproductive structures in the specimens from Tabasco. This work is based on phenological monitoring carried out in a karst limestone locality in Tabasco. The lifespan of pollen and ovulate strobili and their morphological changes throughout development are described. The collections of this new species were compared with specimens of all Ceratozamia species; however, the morphological comparison was focused on the most geographically proximate and morphologically similar species to this new taxon. To evaluate the circumscription of this species, we used geographic, morphological and DNA barcoding criteria. On this basis, we propose a new species of Ceratozamia for Mexico and provide notes on its reproductive phenology. The reproductive structures are the primary resource for its recognition and identification. A taxonomic key for the similar morphological species and all species that occur in Tabasco is presented along with habitat characterisation and a conservation status for C. gigantea. This species, whose distribution is restricted to a small geographic area, increases the diversity of Ceratozamia in Tabasco to three species and affirms the importance of limestone karst as areas for speciation and endemism. During the phenological monitoring, pollinator insects were captured on ovulate strobili at receptivity, observations that have been scarcely documented during this phenophase in Ceratozamia, highlighting the relevance of monitoring reproductive phenological patterns.","PeriodicalId":51321,"journal":{"name":"Kew Bulletin","volume":"70 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141881719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Confined on current evidence to upper submontane forest, the new species is threatened by expanding habitat clearance for farms and is assessed as Critically Endangered. A small tree, attaining 3 – 4 m height, it is the first new species to be added to this Guineo-Congolian tree genus in 50 years, the third recorded from Cameroon and takes the number of species in the genus to eight. It has the highest known altitudinal range (1700 – 1950 m alt.) of any species of the genus. We discuss its discovery in the context of other recently discovered and highly threatened or even extinct plant species in the Cameroon Highlands, and the importance of their conservation. The new species was previously identified as Lychnodiscus grandifolius Radlk., but differs in the shorter length of the distal leaflets (12 – 18 cm vs 22 – 39 cm long); in the abaxial leaf surface lacking glands (vs glands flat and conspicuous); in being sparsely hairy all over (vs glabrous except the main veins) and in its larger flowers, 8 – 11 mm long at anthesis (vs 5 – 7 mm long). We present an identification key of the species of Lychnodiscus and discuss their classification in the context of recent molecular phylogenetic and phylogenomic studies. The authors contend that Lychnodiscus Radlk., previously placed in Cupanieae by Radlkofer, should now be placed in the reconstituted Nephelieae in the revised 2021 intrafamilial classification of Buerki et al., probably close to the genera Aporrhiza Radlk. and Laccodiscus Radlk. However, until the genus is included in molecular studies this cannot be confirmed and a sister relationship remains speculative.","PeriodicalId":51321,"journal":{"name":"Kew Bulletin","volume":"14 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141744485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
