Just came across your discussion on "Shakalu" ..i could not reply there cause i m not a member of that grooup yet.
I have some information that should be useful to you.
The link http://banglapedia.search.com.bd/HT/V_0030.htm tells us that Shakalu is "Yam bean" in English...and its botanical name is Pachyrrhizus tuberosa.
So may be you can update that discussion with this information...if u find it correct.
Thanks and Regards
