I found hundreds of this most unusual plant growing in the grass at the northern end of the picnic area. It is a relative of the ferns and grows from a short slightly tuberous underground rhizome. The aerial parts (which are visible in the photos) consist of a sterile leafblade and an erect fertile spike that carries the spores. These spikes are only about 5 to 8 cm in height. This species is widespread in subtropical and temperate areas throughout the world. (August 2008)
