Abstract: Using the light microscope and SEM, the characteristic of the morp-hological development of the culturing gametophytes of 11 speices in theSelaginellaceae from China have been studied. They are Selaginella tamariscina (Beauv.) Spring, S. helvetica (L.) Link, S. rossii (Bak.) Warb., S.remolifolia Spring, S. sibirica (Milde) Hieron., S. sinensis (Desv.) Spring, S. delicatula (Desv.) Alston, S. heterostachys Kak., S. labordei Hieron. S.nipponica Franch. et Sav., and S. sanguinclenta (L.) Spring. On the basis of the characteristic of the morphological development ofeach species, the possibility of morphological evolution on the female gam-etophytes of Selaginellaceae has been discussed. We consider that the fem-ale gametophtes may be divided into two typies:Shortening equatorialaxif type and Shortening polar axis type. These two typies are identicalwith the views of dividing The genus Selaginella into Hemoerphyllum andHeterophyllum on the sporophytes And the Heterophyllum seems to be grouped, owing to the morphological development of female gametophytes. Amony them the female gametophytyes of 9 species are the first rep-ort.
