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}

(Fabaceae) is a Western European plant, widespread from Northern Morocco to Southern Sweden, with two geographically isolated populations in Calabria (Italy). Based on morphological characters, some authors considered the southern Italian populations as two different species: Genista silana and Genista brutia. Recent phylogeographical studies reveal that the G. silana and G. brutia populations share genetic similarities with some populations of the widespread G. anglica from Northwestern of Iberian Peninsula, despite a distance of approximately 2000 km. Previously, other authors suggested anthropogenic introduction of these plants in the South of Italy, but this hypothesis has not been thoroughly investigated. To unravel the uncertain origin of the isolated Italian populations, we conducted a more detailed study about the genetic relationships between southern Italian populations and Northwestern of Iberian Peninsula populations of G. anglica s.l., using plastid DNA sequences. Our results show identical and similar haplotypes in some of the populations of the Northwestern of Iberian Peninsula and the Italian populations, which supports the hypothesis of a recent anthropogenic introduction.\u0000 ","PeriodicalId":20114,"journal":{"name":"Phytotaxa","volume":"46 14","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138949782","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}
