Seed Morphology of Vitaceae

International Journal of Plant Sciences, 2011
Seeds of Vitaceae can be easily recognized by their unique features, a pair of ventral infolds and a dorsal chalaza knot, but the inter- and intrageneric morphological variation in seed morphology has not been explored in detail. To facilitate identification of genera based on seed morphology, a study of 252 extant seeds representing all 15 genera of ...

Seed Coat Morphology in Gentianopsis (Gentianaceae)

Rhodora, 2010
Abstract Seed coat morphology is examined in 16 taxa of Gentianopsis, Pterygocalyx, and Gentianella, including representatives from 14 taxa of Gentianopsis, to resolve inconsistencies in previous reports and make new observations using a low vacuum mode of SEM. Four characters are proposed to describe variation in seed coat morphology of this group: (1)
