Chionodoxa

''Chionodoxa'', known as glory-of-the-snow, is a small genus of bulbous perennial flowering plants in the family Asparagaceae, subfamily Scilloideae, often included in ''Scilla''. The genus is endemic to the eastern Mediterranean, specifically Crete, Cyprus and Turkey. The blue, white or pink flowers appear early in the year making them valuable garden ornamentals. The common name of the genus is based on the habit of flowering in high alpine zones when the snow melts in spring.
==Taxonomy==

''Chionodoxa'' is distinguished from the closely related genus ''Scilla'' by two features: the tepals are joined at their bases to form a tube rather than being free; and the stamens have flattened stalks (filaments), which look almost like a cup in the centre of the flower. These differences are not considered by some botanists as sufficient to create a separate genus, and ''Chionodoxa'' species are often included in ''Scilla''. ''Chionodoxa'' is also not recognised as a separate genus from ''Scilla'' by the World Checklist of Selected Plant Families,〔(World Checklist of Selected Plant Families: ''Chionodoxa'' Boiss., Diagn. Pl. Orient. 5: 61 (1844). )〕 or the Angiosperm Phylogeny Website.
The taxonomy of the genus is confused. Several of the species are very similar, and the number of species recognized as distinct varies significantly from one source to another. For example, plants occurring in Crete have at one time or another been put into three species: ''C. albescens'', ''C. cretica'' and ''C. nana''. Sfikas' ''Wild flowers of Crete'' recognizes only two of these (''C. cretica'' and ''C. nana''); the Natural History Museum's checklist of the Cretan Flora recognizes only one (''C. nana'', as ''Scilla nana''). The Royal Horticultural Society distinguishes between ''C. forbesii'' and ''C. siehei''; other botanists recognize only ''C. forbesii''.〔
Assuming there are six species, as listed below, three occur in west Turkey, one in south-west Turkey, one in Crete and one in Cyprus.〔 Garden plants have naturalised outside of their native range, e.g. in the UK, Germany, Austria and the Netherlands. A natural hybrid ''C. siehei'' x ''C. luciliae'' also occurs.
