Abstract Pollen grains of Wightia and related genera of Bignoniaceae and Scrophulariaceae were examined under LM and SEM with an attempt to show how the genus Wightia correlates with the two families and therefore further determine its position systematically, and at the same time to clarify Chinese species within the genus Wightia.
The result shows that the size, the character of aperture and the ratio of sexine to nexine of the pollen of Wightia are more similar to that of Scrophulari-aceae than to those of Bignoniaceae, for example the former two taxa have small to medium-sized, 3 -colporate or 2 - 4 colporate (or colpate) pollen grains withsexine equal to nexine.
