| 英文摘要 |
This paper deals with the gametophyte development of an unfamiliar fern recently discovered by the writer in the vicinity of Taipei, Taiwan. The striking characteristics of the plant itself made obvious of its systematic position, belonging to the family Hymenophylaceae, genus Trichomanes and species saxifragoides, Presl. In order to bring about a better understanding of the life cycle of Trichomanes saxifragoides and its phylogenetic relations which are not yet fully known, the writer has studied the stages in the development of its gametophyte based on sufficient materials collected and laboratory cultures of this newly found plant. The obervations made thus far are presented here in this preliminary report. Other problems concerning the life cycle and phylogeny of Trichomanes Presl., in detail, will be treated thereafter. |
