Selaginella species

   

  
Garden plant for id - 200113 ANB-0027 - Mumbai:   I was told that this plant is popularly known as 'miracle plant' since the leaves unfold when they come in contact with water. Would love to know its name if possible.
looks like dried plant of Selaginella sps., a lower plant belonging to Lycopodiaceae.
I would also go for Selaginella sp. a couple of years back i was working on the ethnomedicinal plants of Bihar and Jharkhand area and the same plant (genus) is sold there by the name 'Sanjeevani Booti'.
is it because it plucks up and greens up with rain, ie revives itself, and hence people think it will help them too??? or does it have some restorative properties?
