Locality. "Waste places, not uncommon in the county. A. Fl. 

 June, August. Area, * * * 4. * 



North Division. 



4. North-west District, "In hedges near Bromham," Miss L. 

 Meredith. 



Not unfrequent among rubbish and in waste places, more gene- 

 rally where the soil is calcareous. A highly elegant plant, growing 

 to the height of two feet, with a rather slender round branched 

 stem: the beauty of its finely divided feather-like foliage fully 

 compensates for the inconspicuous character of the inflorescence. 

 It was formerly employed as a remedy in hysteria and dysentery, 

 from its efficacy in restraining the latter, originated the popular 

 name. 



4. S. thalianum, (Gaud.) common Thale Cress, so called after J. 

 Thalius, a German Physician. Engl. Dot. t. 901. Reich. Icones, 

 ii. 60. (Conringia.) 



Locality. On walls, banks, cottage roofs, and dry gravelly soils, 

 frequent. A. Fl. April, May. Area, 1. 2. 3. 4. *

1. South-east District, " Salisbury and its neighbourhood," Mr. 

 James Hussey.

 Major Smith. 



3. South-west District, "Warminster," Mr. Eowden. 



North Division. 



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

 Spye Park walls, by the side of the Chippenham road, near "Wans 

 House," and Monkton Farley. 



This species has the habit of an Arabis, but the cotyledons are 

 incumbent instead of accumbent, characters of so much importance 

 in the generic distinction of this order, that I have not hesitated 

 to follow Sir W. Hooker in retaining it in its present place. Ad- 

 ditional habitats for this species are desired for the Southern as well 

 as Northern part of the county. I have no memoranda for this 

 species in the neighbourhood of Marlborough, where it can scarcely 

 be wanting.
