always) slightly emarginate with an apiculus in the notch, to- 

 gether with the spike-like arrangement of the heads, are marked 

 characteristics of this species, which is very abundant in the 

 valley of Llanberis, Caernarvonshire. I have seen what is appa- 

 rently the same plant from Hope in Derbyshire, Berwick-upon- 

 Tweed, Bembridge in the Isle of Wight, and Edinburgh ; but I 

 have not seen the radical leaves of either of these plants.

Stem often 4-5 feet high, its top and the tops of the branches 

 usually nodding, bearing rather loose racemes of heads. Heads 

 small (usually about the size of a hazel-nut), ovoid with flowers, 

 not umbilicate, mostly globular with fruit, greenish, usually 

 much webbed. Radical leaves acute, longer than broad, broadest 

 at one-third above the insertion of the petiole ; teeth very broad 

 but shallow; petioles hollow, slightly angular, scarcely furrowed 

 above. 



This common plant is known by its small ovoid racemose 

 stalked heads, and its very coarsely dentate, not crenate, leaves.
