Studies of Vietnamese pteridophyte flora
<p>Two new records, <i>Adiantum capillus-junonis</i> and <i>Actinostachys wagneri</i> are reported for Vietnam based on our new collections. A new species <i>Hymenophyllum</i> <i>bryoides</i><i> </i>is described to accommodate its morphological and genetical distinctiveness from other congeneric species. Photographs of key characters, distributions, ecology, and notes of all the above species are provided.</p>
