Abstract:
Testa SEM characters of Lardizabalaceae and Sargentodoxaceae have not been
used in former studies of taxonomy and phylogeny. In this work examined by scanning elec-
tron microscope (SEM). was the testa surface of 5 genera including 15 species of Lardizaba-
laceae and Sargentodoxaceae. Sargentodoxaceae is found quite different from Lardizabalaceae
in its smooth test. The testa sculpture of Akebia, Holboellia and Stauntonia is basically
striate, but that of Sinofranchetia, though striate, is verrucous on striations. Decaisnea is very
isolated for its mosaic testa sculpture.
The tesa examination confirms the rationality of the taxonomic treatment of Sargentodoxa-
ceae by Stapf, the isolated taxonomic position of Decaisnea and Sinofranchetia in Lardizabala-
ceae, and the close interrelationship among Akebia, Holboellia, and Stauntonia.
