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 ...

Primary Vascular Patterns in the Vitaceae
International Journal of Plant Sciences, 2001Vitaceous shoots can be classified into five distinct architectural patterns based on a three‐node sequence of tendril and axillary bud presence. The relationship between two of the more commonly occurring patterns and their primary vasculature was examined.

Woods of the Vitaceae—fossil and modern
Review of Palaeobotany and Palynology, 1994Vitaceoxylon tiffneyi gen. et sp. nov. and Vitaceoxylon carlquistii sp. nov. from the Middle Eocene Clarno formation are the oldest known woods with characteristics of the Vitaceae. They are characterized by a tendency to two diameter classes of vessels, wide and tall rays, and a high proportion of their area is vessel.

Vegetative Features of the Vitaceae
2015This chapter focuses on the nonreproductive features of the grape family, especially the unique and unusual ones. The most unusual is the initiation of the uncommitted primordia directly from the shoot apical meristem (SAM) opposite the leaf primordium.

Reproductive Features of the Vitaceae
2015This chapter discusses aspects of the reproductive features within the Vitaceae from the point of view of development, within a comparative systematics framework. The typical stages of inflorescence initiation and development are illustrated, as well as the variability in mature inflorescence patterns present across the clades.

Noch stets sind die meisten phytochemischen Arbeiten Vitis vinifera und den mit ihr kreuzbaren Wildarten gewidmet. Das ist durchaus verstandlich, obwohl aus taxonomischer Sicht bedauernswert, da Weinbau und Weinbereitung zu den ganz grosen Agrar-Industrien gehoren (1).
