Edge of leaf droplets.. what are these?

[Dinu]

I'd seen them before, but yesterday morning I looked closely at the tiny beads of water forming on the edge of the leaves. I found these on my Balsam, Cyanotis cristata and a purple Tradescantia. Pictures from the first two attached. Earlier I had thought it was the dew but these beads are not on other plants. We have had heavy rains during May which is a summer month with temps touching 37C here with minimum of 21-22C. The air is humid. Due to the rains it was a comparatively cool May, though humid. Someone told me that plants holding more water can exude excess of moisture like this. Is this true and can anyone explain the exact phenomenon?

Oops, I hit 'create thread' before attaching pictures.

Above is Cyanotis. Two pictures below are of Balsam.
I was observing this on Balsam for the first time.

I didn't receive much of rain, I hope you could mail me some.

It's guttation.

Did you felt the effect of cyclone passing to NE India, Cyclone Mora?

Thanks for the word and thread link, Rajesh.
In Chennai rain was predicted... and here it was, in the inland. It has gone to NE now.
