South Division. 



1. South-east District, "Watery places about Salisbury," Major 

 Smith. 



North Division. 



4. North-west District, "About Chippenham," Dr. Alexander 

 Prior. 



It is N. palustre, (De Cand.) and similar in its localities to "N. 

 sylvestre" (R. Br.) which latter plant has not been recorded as yet 

 for Wilts. This species may possibly be not unfrequent : the an- 

 nual not creeping root and the copious short thick pods at once 

 distinguish it from " N. sylvestre." 



Barbarea, (R. Br.) Rocket or Winter Cress. 

 Linn. CI. xv. Ord. ii. 



Name. The " Sanctce Barbara herba." Herb of St. Barbara, of 

 some of the old herbalists probably, from its flowering about her 

 day. 



1. B. vulgaris, (R. Br.) common Yellow Rocket. Bitter Winter 

 Cress. Winter Hedge Mustard. Engl. Bot. t. 443. Reich. Icones, 

 t. ii. 47. 



Locality. In moist waste places, about hedges, banks of ditches, 

 and in marshy meadows, frequent. B. Fl. May, AuguBt. Area, 

 1. 2. 3. 4. 5. 



General in all the Districts throughout the county. A minute 

 species of Tipula or Gall-Gnat, sometimes renders the flower like 

 a hop-blossom, but this metamorphosis does not strictly partake of 

 the nature of galls, as it originates not from the egg, but from the 

 larva, which in the operation of extracting the seed, in some way 

 imparts a morbid action to the juices causing the flower to expand 

 unnaturally. A parasitical white fungus " Uredo Candida" of Persoon 

 is common on the under side of the leaves, and on the stem of this 

 plant in the summer. 



Turritis, (Linn.) Tower Mustard. 

 Linn. CI. xv. Ord. ii. 

 Name. From turris (Lat.) a tower, from the pyramidal growth 

 of the plant.
