3. South-west District, "On the ascent to the ancient camp, 

 called Clerebury, or Clarebury," Dr. Mafon, Nat. Hist. Wilts. 

 " Not uncommon on the Downs near Warminster," Miss Meredith. 

 I have seen as yet no examples from the northern districts of the 

 county. Similar to the last in general habit, but of more humble 

 growth, paler herbage, and larger paler 4-cleft flowers, and essen- 

 tially distinguished by having the two outer and opposite cal3'cine 

 segments ovate and very broad, covering the two inner, which 

 are narrow and lanceolate. 



Menyanthes, (Linn.) Buck or Bog-bean. 

 Linn. CI. V. Ord. i. 



Name. Menyanthes, is a word used by Pliny for a kind of trefoil. 

 Linnaeus derives the name from (tnen) a month, and (anthos), a 

 flower, because the flowers continue open about that time. 



1. M. trifoliata, (Linn.) trifoliate Buck, or Bog- bean. Engl. Bot.

 pany with " Geiim rivafe," Mr. William Salmon.

 Prior.
