Webbia https://oaj.fupress.net/index.php/webbia <p><strong>Journal of Plant Taxonomy and Geography (<em>Webbia</em>)&nbsp;</strong>is a peer-reviewed journal on Plant Systematics, Nomenclature, Phylogeny, Phytogeography and Paleobotany. Most of the contributions deal with the Vascular Plants, but sometime contributions on Briophytes, Lichenes, Fungi and Algae are encouraged.&nbsp;&nbsp;It aims to allow research in&nbsp;botanical topics such as taxonomy, systematics, speciation, morphometrics, molecular phylogeny, conservation, biogeography, and methods.</p> Firenze University Press en-US Webbia 2169-4060 Honoring Philip Barker Webb: the three intriguing stories of Webbia as a genus name https://oaj.fupress.net/index.php/webbia/article/view/12929 <p class="p1"><span class="s1">The name <em>Webbia</em> has been used to describe three different genera: <em>Webbia</em> Spach (Clusiaceae), <em>Webbia</em> DC., <em>nom. illeg.</em> (Asteraceae: Vernonieae), and <em>Webbia</em> Sch.Bip., <em>nom. illeg.</em> (Asteraceae: Astereae). The title of the botanical journal <em>Webbia</em> does not pertain to any of these generic names but is a mere Latinization of the surname Webb, and was created as a patronym that honors the legacy of Philip Barker Webb (1793–1854). The journal is a tribute to Webb’s botanical contributions, and his importance in the development of the collections of the <em>Museo di Storia Naturale di Firenze </em>in the establishment of the <em>Herbarium Webbianum</em>. The journal had an uneasy start, as a book proposal made by the Italian professor (<em>Università di Pisa</em>) Ugolino Martelli to the <em>Società Botanica Italiana</em> to honor Webb was rejected in 1905. The names <em>Conyza obscura</em> DC. and <em>Erigeron capensis</em> Houtt. are lectotypified. The nomenclature of <em>Conyza pinifolia</em> Lam. is revisited, and it is considered a legitimate name. A specimen housed in G-DC is designated as the neotype of this Lamarckian name.</span></p> Javier Francisco-Ortega Riccardo M. Baldini John C.

The new species is a member of the widespread <em>M. melintangensis</em> species complex, but differs from the previously described species in this complex in having a conspicuously papillose corolla head. It is also the only species in this complex that displays a combination of papillose pedicels, calycula and fruits, at least 3–4 inflorescence axes grouped at a node, and relatively small flowers that are clustered at the apex of a raceme (a subumbel) instead of being more evenly distributed along the inflorescence axis.

Kuntze – Theaceae) naturalized in the Atlantic Forest Hotspot https://oaj.fupress.net/index.php/webbia/article/view/12854 <p class="p1">The colonization of Brazil by Portugal left deep marks in Brazil’s current society and economy. The same applies to the country’s biodiversity, with several introduced plants persisting as naturalized or invasive species. Among these, the tea plant, <em>Camellia sinensis</em>, is a notable case. The species was first cultivated in Rio de Janeiro state during the 19th century, but the crops were later abandoned mostly due to the presence of parasite fungi in cultivations, so that the species’ cultivation continued in other states only. During recent fieldwork in the Atlantic Forest in the municipality of Petrópolis, Rio de Janeiro state, naturalized individuals of the tea plant were discovered. This finding, alongside ecological evidence, highlights a new threat to the biodiversity of an area of high species endemism. We provide historical information on the introduction of the species in Brazil and discuss the threats it imposes to the flora in a world hotspot. Our finding adds <em>C. sinensis</em> to the list of naturalized plants of Flora do Brasil 2020 and emphasizes the importance of monitoring the invasive potential of the species in the area, given its allelopathic potential on the germination of other species and competition with native plants.<span class="Apple-converted-space">&nbsp;</span></p> Guilherme Medeiros Antar Roberto Baptista Pereira Almeida Marco Antonio Palomares Accardo-Filho Rafael Gomes Barbosa-Silva Copyright (c) 2022 Guilherme Medeiros Antar, Roberto Baptista Pereira Almeida, Marco Antonio Palomares Accardo-Filho, Rafael Gomes Barbosa-Silva https://creativecommons.org/licenses/by/4.0 2022-04-20 2022-04-20 77 1 177 183 10.36253/jopt-12854 Micro-morphological studies in the genus Balanites Del. in West Africa https://oaj.fupress.net/index.php/webbia/article/view/12026 <p class="p1">We examined the two species of the genus <em>Balanites</em> in West Africa for their foliar and pollen micro-characters. Fresh and herbarium specimens were used for this study. Results showed that the species have overlapping characteristics. Epidermal cells were generally anisodiametric or polygonal; anticlinal walls straight-curved while stomata were anomocytic and surrounded by large guard cells in both species. Trichomes were tectorial and only observed in <em>B. aegyptiaca</em>. Pollen grains were generally single, isopolar, tricolporate, and oblate spheroidal in shape, ranging from 23-23.5µm in <em>B. aegyptiaca</em> and 22-23µm in <em>B. wilsoniana,</em> in length. The exine was generally finely reticulate with indistinct lumina and thin in both species while pollen shape was oblate spheroidal in <em>B. aegyptiaca</em> and prolate spheroidal in <em>B. wilsoniana</em>. Ecological data showed that the species are allopatric but sometimes may be found in same ecological zone. Although the present study supports the co-existence of the taxa as sister species, the overlapping characters as observed also suggest the need for further taxonomic studies to ascertain beyond reasonable doubt, the recent infra-generic classification within the Zygophyllaceae.</p> Emmanuel Chukwudi Chukwuma Kehinde Adegoke Adeniji Luke Temitope Soyewo Temitope Omoniyi Oyebola Oluwaseun Adeniyi Osiyemi Copyright (c) 2022 Emmanuel Chukwudi Chuckum, Kehinde Adegoke Adeniji, Luke Temitope Soyewo, Temitope Omoniyi Oyebola, Oluwaseun Adeniyi Osiyemi https://creativecommons.org/licenses/by/4.0 2022-04-20 2022-04-20 77 1 185 199 10.36253/jopt-12026 Ib Friis, Paulo van Breugel, Odile Weber, Sebsebe Demissew.
