Public Description:

Asplenium septentrionale, commonly known as “forked spleenwort” or “northern spleenwort”, is native to western North America, Europe, and Asia. Like other ferns, this species does not contain flower, fruit or seed. Although it has a vascular systems as seen in flowering plants, it produces spores instead of seeds to reproduce. It is a small fern which grows in dense clusters superficially resembling tufts of grass. It has long, dark stems which support narrow, leathery leaf blades.
