Summary An examination of the native flora over the course of nine years throughout Tanzania by Barry Yinger and Robert Sikawa, co‐founders of the Tanzania Sansevieria Foundation, has resulted in a large number of unknown Sansevieria species being brought into cultivation for the purposes of ex situ conservation, taxonomic examination, and research. In cooperation with the National Herbarium of Tanzania and Potsdam University Botanical Garden, sixteen new species have been described, with many more awaiting this attention. Field work throughout the country has provided insights into the genus as a whole.
Summary We report the rediscovery of the holotype of Tricyrtis macranthopsis Masam. an ornamental herbaceous perennial, endemic to the Kii peninsula, Honshū, Japan, closely related to Tricyrtis macrantha Maxim. T. macranthopsis is illustrated here, and its taxonomic relationships, morphology, ecology and notes on its cultivation are discussed.
Summary Tolpis Adanson is a genus of some 15 species distributed primarily in the Macaronesian archipelagos of the Azores, Canary Islands, Madeira, and Cape Verde Islands. A phylogenomic study resolved Tolpis as monophyletic with the Madeiran endemic species Tolpis macrorhiz a sister to the remainder of the genus. This paper describes the new genus Madeirina to accommodate Tolpis macrorhiz a. The combination of morphological characters distinguishing the new genus from Tolpis sensu stricto is enumerated; the reproductive biology, ecology, chromosome number, conservation status and distribution of the new genus are discussed.
Summary The life and work of the Irish botanist E. Charles Nelson (1951–2024) is explored in the context of his interest in botanical art, especially considering the Irish native and garden floras.
