Yet another edible wild plant ...

I came to know of this just by accident. It is none other than our bright pink flowered coral vine. It's tubers are edible!

Thanks to Google Books ...

...it helped me find the much required missing link, the taxonomic name. I only vaguely remember the Telugu name. Batani. But the term `batani' more commonly refers to garden peas and it has, as expected retrieved cookery websites. When I used bataani and flower it retrieved cookery websites which dealt with garden peas and plaintain flower used as a vegetable. But, there was one Google Book result - Biodiversity in India - which contained the term `batani teega'. Yes! that is the local name and when I searched with that term I landed on its scientific name - Antigonon leptopus, the key to the wealth of world's literature on the plant in question.
