''Vittaria'', the shoestring ferns, is a genus of ferns in the Vittarioideae subfamily of the family Pteridaceae.〔 It had previously been placed in the family Vittariaceae,〔Karl U. Kramer. 1990. "Vittariaceae". pages 272-277. In: Klaus Kubitzki (general editor); Karl U. Kramer and Peter S. Green (volume editors) ''The Families and Genera of Vascular Plants'' volume I. Springer-Verlag: Berlin;Heidelberg, Germany. ISBN 978-0-387-51794-0〕 but that family is no longer recognized.〔Alan R. Smith, Kathleen M. Pryer, Eric Schuettpelz, Petra Korall, Harald Schneider, and Paul G. Wolf. 2008. "Davalliaceae". pages 443-444. In: "Fern Classification". pages 417-467. In: Tom A. Ranker and Christopher H. Haufler (editors). ''Biology and Evolution of Ferns and Lycophytes''. Cambridge University Press. ISBN 978-0-521-87411-3〕 ''Vittaria'' consists of epiphytes, with simple, entire, narrowly linear fronds.〔David J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK. ISBN 978-0-521-82071-4〕 It comprises six species, five of which are native to the neotropics. ''Vittaria isoetifolia'' is native to tropical Africa and islands of the southwestern Indian Ocean.〔Edmund H. Crane. 1997. "A Revised Circumscription of the Genera of the Fern Family Vittariaceae". ''Systematic Botany'' 22(3):509-517.〕 ''Vittaria isoetifolia'' and ''Vittaria lineata'' are known, albeit rarely, in cultivation.〔Anthony Huxley, Mark Griffiths, and Margot Levy (1992). ''The New Royal Horticultural Society Dictionary of Gardening''. The Macmillan Press,Limited: London. The Stockton Press: New York. ISBN 978-0-333-47494-5 (set).〕 ''Vittaria'' was named by James Edward Smith in 1793 〔''Vittaria'' in International Plant Names Index. (see ''External links'' below).〕 in ''Mémoires de l'Académie Royale des Sciences (Turin)''.〔James Edward Smith. 1793. ''Mémoires de l'Académie Royale des Sciences (Turin)'' 5:413, pl. 9.〕 The generic name is derived from the Latin, ''vitta'', meaning "a band or ribbon".〔Umberto Quattrocchi. 2000. ''CRC World Dictionary of Plant Names'' volume IV, page ?. CRC Press: Boca Raton; New York; Washington,DC;, USA. London, UK. ISBN 978-0-8493-2673-8 (set). (see ''External links'' below).〕 In 1990, ''Vittaria'' was defined broadly and estimated to have between 50 and 80 species.〔 The genus is difficult to divide into species, and many of the species are only doubtfully distinct. In a 1997 revision of the vittarioid ferns, only 34 species were recognized in ''Vittaria'' sensu lato.〔 Twenty of these were transferred to ''Haplopteris'' and eight to ''Radiovittaria'', leaving only six in ''Vittaria''.〔 == Species == ''Vittaria'' includes the following species (but this list may be incomplete). * ''Vittaria lineata'' * ''Vittaria appalachiana'' * ''Vittaria dimorpha'' * ''Vittaria flavicosta'' * ''Vittaria graminifolia'' * ''Vittaria isoetifolia'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vittaria」の詳細全文を読む スポンサード リンク
