Galanthus earlier authors had mainly relied on was shown to be highly homoplasious. A number of species, such as "G. nivalis" and "G. elwesii" demonstrated intraspecific biogeographical clades, indicating problems with speciation and there may be a need for recircumscription. These clades were assigned names, partly according to Davis' previous groupings. In this model clade Platyphyllus is sister to the rest of the genus. By contrast another study performed at the same time, using both nuclear and chloroplast DNA but limited to the 14 species found in Turkey, largely confirmed Davis' series and subseries, and with biogeographical correlation.

Flower Garden (solitaire) bouquet." The top cards of each flower-bed and all of the cards in the bouquet are available for play. Cards can only be moved one at a time and can be built either on the foundations or on the other flower beds. The foundations are built up by suit, from Ace to King (a general idea of the game is to release the aces first). The cards in the garden, on the other hand, can be built down regardless of suit and any empty flower bed can be filled with any card. The cards in the bouquet can be used
