Galanthus (convolute). He merged "Nivalis" and "Plicati" into series "Galanthus", and divided "Latifolii" into two subseries, "Glaucaefolii" and "Viridifolii" . Early molecular phylogenetic studies confirmed the genus was monophyletic and suggested four clades, which were labelled as series, and showed that Davis' subseries were not monophyletic. An expanded study in 2013 demonstrated seven major clades corresponding to biogeographical distribution. This study used nuclear encoded nrITS (Nuclear ribosomal internal transcribed spacer), and plastid encoded "matK" (Maturase K), "trnL-F", "ndhF", and "psbK–psbI", and examined all species recognised at the time, and also two naturally occurring putative hybrids. The morphological characteristic of vernation that
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
