Horsetail

Description:

Green plant, about 15 cm in height. The horsetails are a group of plants in the genus Equisetaceae which is more than 300 million years old and at that time could be up to 30 meters in height. They reproduce using spores instead of seeds.

Habitat:

Moist forest ground

Notes:

I am not sure about the species since it is not fully developed yet, but it is definitively a horsetail-specimen.
