GENUS XX\'.-OphiOglOSSUm, Linn. Adders Tongue. 



O. \ I LCiATlM, Linn. Adders Tongiu: Rhizome fleshy, with a descending- axis, 

 spreading: fleshy roots, and a sheathed terminal bud or growing- point. Frond a few 

 inches in heigfht ; stipe erect, succulent, hollow, bearing- a sessile leaf-like frond, sub- 

 tending: the erect fertile peduncle which bears the flesy spore cases imbedded in a series 

 or row on each marg-in of the spike ; they ultimately split horizontally and give it a 

 toothed appearance. Sometimes the fruit-spike is forked, and it is so fi.gured in very 

 old books. This probably orig^inated the name Ophiog-lossum, or Adder's Tong-ue.
