amit uid 1 1392011:  Attaching photo of a climber collected from Chopta, Uttarakhand in Quercus
forest at an altitude of about 2900 mts. Please help in identification.

Dioscorea is also possibily, although I thought leaves are more rigid like Smilax. At the same time stipule tendrils of Smilax are not visible in the photograph. Perhaps another photograph with node in focus will help.

I had doubt of it being Discorea deltoidea I am attaching another picture may it help in further identification

Yes Dioscorea. The leaves look thicker than D. deltoidea, but then this could be an older branch.

Sorry no picture of tubers

D. deltoidea i think

after changing the soil in the palm pot this leaf has sprouted after some days. I waited for some days but
it is not growing further . no new leaves no flowers is it wild?
Date/Time- Aug 2011
Location-Place, Altitude, GPS-Pune
Habitat- Garden/ Urban/ Wild/ Type- i do not know
Plant Habit-Tree/ Shrub/ Climber/ Herb- just a leaf
Height/Length- 4-5 cms

Leaves Type/ Shape/ Size- just a single smart looking leaf

looks like Dioscoria bulbifera

That was in september, has it grown any in the meantime: what is it doing… update possible?

I had seen it about a month ago. It was the same only the color of the leaf had become green. When I went to check today it is not there anymore. Probably as it was not growing further the gardener removed it.
