Botanical history and nomenclature of three generic eponyms pertinent to the conquest of Tenerife by the Kingdom of Castile (1494 – 1496)
摘要
The Canary Islands genera Lugoa DC. (accepted name Gonospermum Less., Asteraceae, honouring Alonso Fernández de Lugo from Andalusia, Spain), Bencomia Webb & Berthel. (Rosaceae, honouring Mencey Bencomo from Tenerife, Canary Islands, Spain), and Tinguarra Parl. (Apiaceae, honouring Mencey Bencomo’s brother Tinguaro) are dedicated to the main leader of the Spanish troops and to the two resistance chief warriors involved in the invasion and conquest of the island of Tenerife by the Kingdom of Castile in the late 15th century. Biographical accounts of these three personalities are presented; the botanical history, systematics, and phylogenetics of these three genera were revised; and nomenclatural diagnoses are provided. Distribution maps are included for the Canary Islands and Madeira endemics. The research involved assessing holotypes for three species (viz., B. brachystachya Svent., B. exstipulata Svent., and B. sphaerocarpa Svent.); lectotypes are designated here for the names Anthemis revoluta C.Sm. (Asteraceae), B. moquiniana Webb & Berthel., Poterium caudatum Aiton (Rosaceae), P. spinosum var. crispum DC., P. spinosum var. inerme DC., and Seseli cervariifolium DC. (Apiaceae, kindly typified by M. W. Callmander). A review of known botanical artworks was undertaken for species attributed to these genera, and illustrations were found for Athamanta cervariifolia (DC.) DC., A. montana (Christ) K.Spalik, Wojew. & S.R.Downie (Apiaceae), B. caudata (Aiton) Webb & Berthel., B. brachystachya, B. exstipulata, B. sphaerocarpa, G. revolutum (C.Sm.) Sch.Bip. (Asteraceae), Marcetella maderensis (Bornm.) Svent., and M. moquiniana (Webb & Berthel.) Svent. (Rosaceae). Ecological features and conservation actions were also reviewed. Two of the species are Critically Endangered (CR category of IUCN for B. brachystachya and B. sphaerocarpa), M. maderensis is listed as IUCN Endangered (EN) category, and G. revolutum and B. exstipulata are listed under the IUCN Vulnerable (VU) category. The rest of the species have not been red listed yet. Only three species (B. exstipulata, B. sphaerocarpa, and B. caudata) have been the subject of conservation action plans, genetic research, or population viability analyses.
