Summary
Pinter M., Martínez-Azorín M., Crespo M. B., Alonso-Vargas M. Á., Pfosser M. & Wetschnig W. 2020. A taxonomic revision of Tenicroa (Hyacinthaceae, Urgineoideae) – including four new species and two new combinations. – Phyton (Horn, Austria) 60: 61–92, with 11 figures.*
Within the framework of a taxonomic revision of Hyacinthaceae subfamily Urgineoideae (Asparagaceae tribe Urgineeae) combining morphological and genetic data from numerous samples across its whole range of distribution, we here present a taxonomic revision of Tenicroa. Species of Tenicroa have a very intricate history and therefore, unlike many others, they have been placed by time in eight different genera. Tenicroa is characterized by having (mostly) synanthous leaves and sheathing cataphylls with raised darker transversal ridges, diurnal stellate flowers with white tepals having a distinct narrow, reddish-brown or greenish band, subbasifixed anthers, and the ovary elliptic-oblong to oblong, with an elongate, deflexed and often sigmoid style, and a papillate stigma. In this context, we here describe four new species (T. applanata, T. fibrosa, T. namibensis, T. polyantha) and present two new combinations (T. flexuosa, T. unifolia) in this genus. An identification key is provided for the 12 accepted species in the genus.
