Abstract:
the comparative studies of morphology and anatomy of 19 species of Chinese
Woodsiaceae are reported in the present paper. It includes anatomy of root, rhizome, rachis
and joint on stipe; comparative morphology of the fronds and its parts, trichomes and indusia
and an observation of the spores under SEM. The information is applied to discussing phylo-
geny and systematics briefly. The anatomical studies do provide taxonomic studies with evi-
dence so that they should not be abandoned. For example, the stipe joints of Woodsia have
two types, the stipe joint below the attachment point of the base pair of pinnae and the stipe
joint just at the attachment point of that; the abscission layer of the former does not have pin-
na trace in it and the basic chromosome number is 39. However, the abscission layer of the
latter does and the basic chromosome number is 41. It is obvious that the anatomical cha-
racters can be used for infrageneric subdivision of Woodsia.
