Species Synonyms

Within botanical registers, the scientific nomenclature accepted for the classification of this species is Vitis pedicellata Lawson. No other synonyms have been documented.

Historical Background and Geographical Distribution

Vitis pedicellata stands out as the least understood species within the genus Vitis. Its classification as an independent taxonomic entity by the researcher Lawson is still accepted by viticulturists with a certain degree of doubt. The initial description was compiled based on herbarium specimens from the Martius collection gathered in 1848. While J. E. Planchon agreed with Lawson’s conclusions and included the plant in his taxonomy, the authors of this encyclopedia emphasize that due to strong morphological similarities, Vitis pedicellata may represent merely a local high-altitude form of Vitis lanata.

The native range of this vine is extremely limited and confined to a highly specific region. Vitis pedicellata is endemic to the Himalayan mountain system. The only documented wild populations were recorded in the high-altitude zone on the slopes of Mount Kathee at an elevation of approximately 2,100 meters (7,000 feet) above sea level.

Botanical and Morphological Description

  • Growth Habit and Shoots: The plant develops as a typical climbing vine. The tendrils are intermittent. Young shoots and unfolding leaves are densely covered with a thick, felted pubescence of a whitish-rusty coloration. As the cane matures and hardens, this pubescence sheds completely.
  • Leaf: The leaves are medium in size and cordate. The petiolar sinus is open with a smoothed base. The leaf blade can be entirely entire or feature three weakly indicated lobes. The leaf margins are divided into wide but very short and obtuse teeth. The upper surface of the mature leaf is glabrous, while short soft hairs persist on the lower surface exclusively along the path of the primary veins.
  • Inflorescences and Berries: The inflorescence presents as a regular, dense cylindrical-ovoid cluster. The species is characterized by a distinctly pronounced functional dimorphism of the flowers. Male specimens produce exclusively staminate flowers situated on exceptionally long, slender, thread-like pedicels, which served as the basis for the specific name. On female, fruit-bearing vines, the flowers feature significantly shorter and more robust pedicels. The ovary is rounded-ovoid, transitioning into a long, highly conspicuous style. The morphology of mature berries and the anatomical structure of the seeds were not described at the time the primary source was compiled.
