摘要: 本文研究了无粉银粉背蕨配子体的发育, 孢子四面体, 三裂缝, 孢子萌发为带蕨型, 丝状体2-12个细胞长, 单列或多列, 原叶体裸露, 心脏形, 生殖器较大, 该配子体表现为原始的性状。原叶体发育为铁线蕨型, 或水蕨型, 或两者之间的类型, 在发育中的变异大, 体现中国蕨科配子体的特点。

Abstract: The spore is tetrahedral, trilete.The patterns of spore germination is of Vittaria-type (nayar 1971). Generally the germ filaments develop 2-12cells long, uniseriate, or multiserite. The prothalli are naked and cordate.The sex organs are rather large.It seems that these are common primitive characteristics of the family.The prothallial development is the Adiantum-type, or Ceratopteris-type (Nayar 1971) or the mediate between the two types. It implies that the prothalli are more variable in the development of the taxon, and also reflect the characteristics of the family.
