SYSTEMATIC ANALYSIS OF THE GENUS SCILLA L. S. L. (HYACINTHACEAE) (GEM.)

A historical survey is given showing the changes of what belonged to t he genera Scilla L., Hyacinthus L. and Ornithogalum L. during the cent uries. Many efforts have been made to find a natural system and to enl ighten the phylogeny. According to karyological and morphological char acters the species of the extensive genus Scilla L. form related group s all of which have been confirmed by DNA sequencing data. Therefore i t is very reasonable to address these groups as genera. The Scilla of the ancient Greeks and Romans and some relative genera form the subfam ily Urgineoideae SPETA subfam. nova. The genera Urginea STEINH., Drimi a JACQ., Thuranthos WRIGHT, Charybdis SPETA nom. novum, Rhadamanthus S ALISB., Fusifilum RAF., Rhadamanthopsis (OBERM.) SPETA stat. novus, Ig idia SPETA gen. novum, Ebertia SPETA gen. novum, Urginavia SPETA gen. novum, Tenicroa RAF., Urgineopsis COMPTON are dealt with. The Urgineoi deae are clearly distinct from the Ornithogaloideae SPETA subfam. nova and the Hyacinthoideae LINK. Most species of Scilla s. l. belong to t he Hyacintheae DUMORT. Scilla L. s. str. (= S. bifolia-relationship an d Chionodoxa BOISS.), Schnarfia SPETA gen. novum (= S. messeniaca-rel. ), Zagrosia SPETA gen. novum (= S, persica-rel.), Nectaroscilla PARL. (= S, hyacinthoides-rel.), Chouardia SPETA. gen. novum (= S. litardier ei-rel.), Fessia SPETA gen. novum (= S. hohenackeri- and S. bisotunens is-rel.), Pfosseria SPETA gen. novum (= S. bithynica-rel.), Othocallis SALISB. (= S. siberica-rel.), Prospero SALISB. (= S. autumnalis-rel.) , Hyacinthoides MEDICUS (= S. non-scripta-rel.), Tractema RAF. (= S. v erna-rel.), Oncostema RAF. (= S. peruviana-rel.), Autonoe (WEBB & BERT H.) SPETA stat. novus (= S. haemorrhoidalis-rel,), Barnardia LINDLEY ( = S. scilloides-rel.), while Ledebouria ROTH (= S. hyacinthoides-rel.) , Schizocarphus MERWE (= S. nervosa-rel.), Resnova MERWE, Avonsera SPE TA gen. novum, Merwilla SPETA gen. novum and Pseudoprospero SPETA gen. novum belong to the Massonieae BAKER. The South American genus Oziroe RAF, forms the subfamily Oziroeoideae SPETA subfam, nova. The North A merican genus Camassia LINDLEY belongs to the Chlorogaloideae SPETA su bfam. nova. Because of the new genera 128 new combinations for specifi c names were necessary.
