1b. Ampelopsis vitifolia subsp. hazarganjiensis Nazim & Qaiser, subsp. Nov.


Frutex erectus, caulis glaber, cortex decortinaris, ramii juveniles pubescetes, folia reniformes vel cordates, basis profondant vadum cordata, dentatus cum acutibus triangularibus dentibus, superficies inferior pubescentis, folia vetera pubescentis solum in nervibus.

Plant erect shrub, stem glabrous, bark peeling, young branches pubescent. Leaves reniform or cordate, not lobed, deeply or shallowly cordate at base, dentate with acute triangular teeth, lower surface pubescent, older leaves pubescent on nerves only. Inflorescences pubescent, pedicel glabrous.

This taxon differs from the sub sp. vitifolia in having hairs on the lower surface of the leaves and peduncle, shape of the leaves are reniform- deeply cordate. The plant is not climber as in former taxon. The two subspecies are also geographically isolated. The former is distributed in Persia, Afghanistan and northern region of Pakistan from Rawalpindi to Chitral while the later is restricted in the type locality near Quetta, Baluchistan.

Holotype: Reserved Forest Valley of Hazarganji, near Quetta. M. Qaiser & A. Ghafoor 1327 (KUH).

Distribution: Endemic to Quetta, Baluchistan.

While studying Ampelopsis vitifolia group we have come across with a specimen from Swat, M. Qaiser & Ampelopsis Ghafoor 4641 (KUH) which differs from Ampelopsis vitifolia (Boiss) Planch. by having tendrilar habit, leaves tomentose beneath and hairy on nerves above. The fruits are also rugose. It may turn out to be a new species, however, more material is needed for proper evaluation of this taxon.
