山东石松类和蕨类植物新记录

New records of lycophytes and ferns from Shandong Province

该研究报道了山东地区4种1变种和1变型石松类和蕨类植物新记录,分别是石松类的伏地卷柏(Selaginella nipponica Franch.et Sav.),蕨类的小戟叶耳蕨[Polystichum hancockii(Hance)Diels]、阔羽贯众(Cyrtomium yamamotoi Tagawa)、粗齿阔羽贯众[C.yamamotoi Tagawa var.intermedium(Diels)Ching et Shing ex Shing]、小羽贯众[C.fortunei J.Sm.f.polypterum(Diels)Ching]、远叶瓦韦[Lepisorus ussuriensis var.distans(Makino)Tagawa]。同时采用扫描电镜对其孢子形态进行了观察,该研究结果为其分类鉴定提供了孢粉学依据。

Four species,one variety and one form of lycophytes and ferns are reported for the first time from Shandong Province. They are Selaginella nipponica Franch. et Sav.,Polystichum hancockii（ Hance） Diels,Cyrtomium yamamotoi Tagawa,C. yamamotoi var. intermedium（ Diels） Ching et Shing ex Shing,C. fortunei J. Sm. f. polypterum（ Diels） Ching,and Lepisorus ussuriensis var. distans（ Makino） Tagawa respectively. The spore ornamentations are examined by means of scanning electron microscopy（ SEM） to facilitate the palynology identification of these species.
