Abstract

In the last issue of taiwania(1) we discussed the Selaginella of Taiwan. A key, based on stem anatomy characters,was given to the known species,and descriptions of the anatomy of each was given.This study is still being continued. Plate I gives illustrations of six species. S. doederleinii Hieron.shows a stem without an aerenchyma zone.The cortex has an outer thick walled, lignified zone and an inner parenchyma zone which extends to the stele.
