 pale yellowish green in colour. Fertile branch erect, a simple 

 spike on an elongate foot-stalk proceeding from the inner base 

 of the sterile branch.

Rhizoma a corm-like crown. 



Koots thick, brittle, and spreading horizontally.

 narrow and oval. The plant also is much later in the year in 

 coming to maturity.
