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 B. aegyptiaca. Pollen grains were generally single, isopolar, tricolporate, and oblate spheroidal in shape, ranging from 23-23.5µm in B. aegyptiaca and 22-23µm in B. wilsoniana, in length. The exine was generally finely reticulate with indistinct lumina and thin in both species while pollen shape was oblate spheroidal in B. aegyptiaca and prolate spheroidal in B. wilsoniana. 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.","PeriodicalId":39391,"journal":{"name":"Webbia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47686549","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 same applies to the country’s biodiversity, with several introduced plants persisting as naturalized or invasive species. Among these, the tea plant, Camellia sinensis, 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 C. sinensis 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.

It was established originally as a joint endeavor between sugar magnate Edwin F. Atkins and Harvard University in 1901. Between 1925 and 1934, the research yacht Utowana performed ample plant germplasm collections for the USDA in the New and Old World as well as archeological and zoological surveys in the Neotropics. The botanical expeditions were conducted mostly, under the leadership of David Fairchild. In this contribution we review to what extent Utowana expeditions and collections were instrumental in building the living collections of Cienfuegos Botanical Garden. A total of 278 accessions (comprising 254 species) were introduced into this garden directly or indirectly through these expeditions. Currently 57 of these species (132 individuals) are still part of its living collections. Interestingly, five of the Caribbean expeditions of this research yacht carried plant material between the Cienfuegos Botanical Garden and two other botanic gardens that were operated by US entities, namely the Lancetilla Botanical Garden in Honduras (owned by the United Fruit Company) and the Summit Gardens in Panama City (managed by the Panama Canal governmental agency). Our study also shows that plant material collected during Utowana expeditions was sent from Old World and Caribbean Island botanic gardens to Cienfuegos Botanical Garden. Thomas Barbour, director of this botanical institution between 1927 and 1946 joined four of these plant hunting endeavors. He provided strong support for the growing of the Cienfuegos Botanical Garden living collections with plant material collected during Utowana expeditions.
