Nearer to E. hyemcde than to E. tradhyodon. This is the only 

 Equisetum of the present section whose stems are annually 

 deciduous. As compared with E. hyemale, the stems are much 

 more slender and flexile, and taper to a fine point ; the ribs 

 are less numerous; the sheaths a little looser, and their 

 brown appendages more persistent; as in E. hyemale, the 

 black mark at the bottom of the sheaths is usually truncate 

 at the base, and seldom runs down upon the ribs as in E. 

 tradhyodon and the others. 



It is worth inquiry whether the plant which grows on the 

 sandhills at Dundrum, Down, above given under E. hyemcde, 

 may not really belong to E. Moorei. 



E. tradhyodon (A. Braun.) — E. Madkaii (Newman).
