Our specimen accords very well in the general characters and 

 structure to the definition of the mentioned species. Lyngbye 

 gives no illustration of the cellular structure of his plant ; but the 

 figures delineated by Kutzixg are satisfactorily applicable to our 

 plant. The longitudinal splitting of fronds in the upper portions 

 seems to be due to the age. Most of our specimens have their 

 herniated lobes simple and undivided.
