These taxa are further endemics of the Horn of Africa biodiversity hotspot and have highly restricted ranges. Barleria biramosa was previously included within B. punctata Milne-Redh., another range-restricted endemic of the Horn of Africa region form northeast Ethiopia and northern Somalia; an updated description of B. punctata is therefore provided. Notes on the habitat requirements and conservation status (extinction risk) of the species are provided. Barleria biramosa is considered to be globally Endangered whilst B. compacta subsp. minima is currently assessed as Least Concern; the published assessment of Vulnerable for B. punctata is confirmed.

Nomenclatural types were cited in various ways, depending on the information and photographs available to the author before 2008. For numerous names, lectotype designations were not accompanied by “here designated” or a similar expression, which is required by the Internation Code of Nomenclature starting from 1 January 2001, therefore those designations are not valid. Also, the barcodes of type specimens were not cited in that treatment, because at that time, it was not common practice to cite that information, especially in floristic treatments, and also because barcodes were not yet assigned to specimens in many herbaria. The type citations are here corrected, type citations correctly cited with additional information added, and designate lectotypes or neotypes of names that still need to be designated, are deginated. A total of 81 lectotypifications and 11 neotypifications are here presented. A list of names newly typified is available in Appendix 1. Updates of the taxonomic and systematic changes that occurred during the last 15 years, are provided. Major changes regarding generic delimitations, mostly in the tribes Palicoureeae, Psychotriae, and Spermacoceeae, have recently been proposed, and numerous new combinations have recently been published by several authors, which are here included. Following those recent generic rearragements, three new combinations in Palicourea are here published, namely P. leiocarpa, P. stachyoides, and P. subtriflora.","PeriodicalId":39391,"journal":{"name":"Webbia","volume":"58 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140231036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study demonstrated how leaf architecture can be equally important for plant varieties as well. The leaf architecture of four Hibiscus rosa-sinensis L. varieties namely ‘Reddy or Not’, ‘Nay Isa’, ‘Lolay’, and ‘Saskia De Lang’ from the Institute of Plant Breeding was studied. A total of 150 leaf specimens were digitized, examined, measured, and described. The semicraspedodromous pattern of the secondary veins and the angle between the 3° to 1° vein were characters found to have taxonomic significance in describing H. rosa-sinensis species while the angle of the 2° vein was important for delineating H. rosa-sinensis varieties. The resulting dendrogram from the cluster analysis grouped all the H. rosa-sinensis from the outgroup and further created three subclusters that were closely related.","PeriodicalId":39391,"journal":{"name":"Webbia","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136360094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
