Brenchley . — The Weeds of Arable Land . III. 
Filago ger manic a. Distributed on sandy and chalky soils. 
Gnaphalium uliginosum . Characteristic of sandy soils. (The records 
for this plant obtained in 1910 and 1912 agree as to its habitat, and so do 
not fall into line with the usually accepted idea that it is a denizen of moist 
places.) 
Matricaria Chamomilla. Occurred either on sand or heavy loam. 
Usually infrequent, but once dominant on sand. 
Matricaria inodor a . Distributed over all types of soil and occasionally 
dominant on light and sandy loams. 
Senecio vulgaris. Found on all soils. Once dominant on sand. 
Sonchus arvensis. Associated with all soils, but more especially with 
heavy loam and clay. Occasionally dominant. 
Tussilago Farfara. Practically confined to clay and the heavier 
loams. Never dominant. 
Campanulaceae. Legousia hybrida ( Campanula kybrida). Occurred 
on the lighter soils, though infrequent on sand. Absent from clay. Never 
dominant, often scarce. 
Primulaceae. Anagallis arvensis. Associated with all types of soil, 
but when it occurred on chalk it was scarce in distribution. Never 
dominant. 
Boraginaceae. Echiumvulgare. Characteristic of sand. Once dominant. 
Lycopsis arvensis. Confined to light sandy land — apparently soils may 
be calcareous or not. Usually occasional or scarce. 
My os otis scorpioides (M. arvensis ). Chiefly on sand and loam ; rare 
on chalk. Never dominant. 
Convolvulaceae. Convolvulus arvensis. Universally distributed as to 
soil, and frequently dominant. One of the commonest weeds, and often seen 
on root land before the seeds come up, in company with Cirsium arvense. 
Scrophulariaceae. Bartsia Odontites. Chiefly associated with loam ; 
never seen on chalk. Twice dominant on heavy loam. 
Linar ia Elatine. Characteristic of heavy soils. Scarce. 
Linar ia minor. Associated with sandy soils. Infrequent. 
Linaria vulgaris. Characteristic of chalky soils. Usually distributed. 
Veronica agrestis. 1 Practically confined to light and sandy soils ; 
from chalk. Rarely dominant. 
Veronica arvensis. Chiefly on the lighter soils ; scarce on chalk. 
Never dominant. 
Veronica hederaefolia. Associated with sand and light sandy loams. 
Absent from clay and chalk. Once dominant on loam. 
1 The exact distinction between V. agrestis and V. T oarnefortii was not recognized at the 
beginning of the season’s work, so possibly a few records of V. Tournefortii have been classed as 
V. agrestis , but not vice versa. However, it is evident that the error has not in any way affected the 
final results except as to the exact number of records of each of the two species.
