REPORT OF THE LONDON BOTANICAL EXCHANGE CLUB. 147 
Equisetum Moorei, Newman. Sandhills, coast of Wexford, Ireland ; 
Mr. A. G. More 
Mr. More sends a few barren specimens of this very remarkable 
plant, which is said to differ from its allies, by having herbaceous 
stems ; though Mr. More hints that this may be owing to the exposed 
places in which it grows (Journ. Bot. p. 208), but has or has not this 
point been tested by cultivation? The teeth are wholly black, not 
white, as stated by Mr. Newman, and have the tips much more per- 
sistent than in Æ. hyemale, closely resembling those of E. trachyodon, 
A. Braun, but the sheaths are loose, and the stems with a comparatively 
large central hollow, as in Æ. hyemale.
