A detailed description of the new species including colour photographs and an identification key to distinguish currently accepted Ochradenus species are provided. A preliminary conservation assessment of the species is also conducted under IUCN categories and criteria at the global level, resulting in the proposal of the Endangered category.

The only wild Fragaria species described in Chile is the octoploid Fragaria chiloensis. In a group of Fragaria accessions from southern Chile including Fragaria chiloensis subsp. chiloensis f. patagonica individuals, an accession named Fragaria-MEN, caught our attention because it shows notable phenotypic differences compared to the rest of the accessions. Fragaria-MEN was collected near the Menetue hot springs (Araucania Region, Chile) and differs from the other F. chiloensis plants mainly in leaf morphology. Due to these differences, we carried out a full morphology description of Fragaria-MEN individuals and then a characterization of the chromosomes and genome size to verify the ploidy level. Morphological analysis reveals close vegetative and reproductive characteristics shared with the non-native diploid Fragaria vesca ‘Hawaii’ species. We also observed a DNA amount according to the diploidy (2n = 2× = 14) revealed by cytological analysis of chromosomes. We propose Fragaria-MEN as F. vesca population that should have been introduced and now is naturalized in the Araucania Region of Chile.","PeriodicalId":20114,"journal":{"name":"Phytotaxa","volume":"4 2","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139153482","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}

The new species is placed in section Chamaesiphon where it appears to be vegetatively and floristically most similar to C. rehmannii (formerly Brachystelma foetidum). Ceropegia strophanthiflora can, however, be readily distinguished from this species by its strikingly colourful greenish-yellow flowers with bright purple markings and purplish-pink vibratile hairs fringing the corolla lobe bases. Most remarkable, however, are the unusually long, slender and twisted corolla lobes much reminiscent of flowers known in Strophanthus; hence the name C. strophanthiflora. There are no other known South African species exhibiting such flamboyant flowers. Concerningly, this spectacular new species may be at the brink of extinction as only very little habitat remains which is under severe anthropogenic threat. Brachystelma tanzaniense, a species with long and slender corolla lobes from Tanzania, is transferred to Ceropegia section Chamaesiphon under the proposed new name C. dodomaensis. Moreover, the blocking name for this transfer, C. tanzaniensis, is reduced to a synonym of C. cordiloba for which we designate a lectotype.","PeriodicalId":20114,"journal":{"name":"Phytotaxa","volume":"178 4","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139153711","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}
