Hybrids of monocots in the flora of Ukraine: Preliminary synopsis
Keywords:
hybrid; monocots; Liliopsida; flora of Ukraine; accepted name; nomenclature; synonym
Abstract
Monocots include ca. 74 000–85 000 species. It is one of the most species rich, ecologically and economically important groups of plants. At the same time, monocots are a key component of ecosystems and have utilitarian significance. In agriculture the majority of the biomass produced comes from monocots. Many plants from this group are used as ornamentals or medicinal plants. This work is devoted to the study of the nomenclature of monocot hybrids in the flora of Ukraine. In general, there are many unsolved problems in the nomenclature of hybrids. Numerous names require clarification. The aim of this study is to compile a list of intergeneric and interspecific hybrids of monocots in the flora of Ukraine. This list includes wild hybrids, as well as cultivated ones that grow spontaneously in the wild. The list of hybrids is compiled mainly on the basis of literary sources. The names of taxa and nothotaxa are indicated according to IPNI. Formulas of the hybrids, basionyms and synonyms are given for the hybrids. The list of monocots' hybrids in the flora of Ukraine offered here includes 87 hybrids. There are many hybrids in the following families: Cyperaceae (20), Orchidaceae (25), Poaceae (22) and Potamogetonaceae (8). In other families there are not many hybrids: Amaryllidaceae (1), Araceae (2), Asparagaceae (1), Commelinaceae (1), Iridaceae (1), Juncaceae (4), Liliaceae (1), Typhaceae (1). There were a number of difficulties during the preparation of this article: 1) there is not enough information, the hybridization of plant species is poorly studied in Ukraine, 2) it is difficult to draw a clear line between hybrids and species of hybridogenic origin, 3) disputed status of parental taxa (i.e. different researchers consider parental taxa in different ranks). Therefore, this list should be considered preliminary.References
