144 Brenchley . — The Weeds of Arable Land . III. 
Geranium dissectum. Associated with heavy soils. Never dominant. 
Geranium molle (including var. aequale ). Confined to light and chalky 
soils. Once dominant on sand, but usually distributed. 
Geranium pusillum. Only seen on light and chalky soils. Never 
dominant. 
Rosaceae. Alchemilla arvensis. Characteristic of light and of sandy 
soils, very rare on chalk. Occasionally dominant, usually distributed. 
Potentilla Anserina. Chiefly associated with medium soils, less fre- 
quent on sand and rare on clay. Occasionally dominant. 
Potentilla reptans. Occurred on the heavier soils, especially clay, but 
never seen in any quantity. 
Umbelliferae. Daucus Carota. Associated with all types of soil and 
occasionally dominant. 
Scandix Pecten-veneris . Found on all soils except chalk, though seen 
occasionally on chalky loam. Once dominant on light loam. 
Rubiaceae. Galium Aparine . Chiefly on heavy loam and clay. 
Never dominant, and only seen frequently at Bressingham and Harleston. 
Galium sp. Distributed on all types of soils. (This was a species 
which defied identification. The plant grew flat against the ground, in 
a kind of mimic rosette, the leaves usually being in whorls of four. In 
many ways it resembled a squat form of G. Aparine , but it was never seen 
in flower or fruit. This form was only seen in West Norfolk, in the districts 
round Swaffham and Snettisham ; G. Aparine occurred alongside it in some 
cases.) 
Sherardia arvensis. Found on all types of soil, but more usually 
on the lighter loams and chalk. Usually occasional or scarce, but generally 
distributed on chalk. 
Dipsaceae. Scabiosa arvensis. Chiefly on light and sandy soils, 
absent from clay. Distributed or scarce. 
Compositae. Anthemis arvensis. Chiefly on sandy soils and chalk. 
Very rare on clay. Occasionally dominant. 
Anthemis Cotida. Usually occurred on loam, but not often seen. 
Artemisia vulgaris . Distributed on light calcareous soils. 
Carduus nutans. Occurred on light and calcareous soils. Once domi- 
nant on sand. 
Centaur ea Scabiosa. Associated with light and chalky soils. Never 
seen on clay. Once dominant on sand. 
Chrysanthemum segetum. Confined to non-calcareous sand. Not very 
frequent, but usually dominant when present. 
Cichorium Intybus. Associated with chalky soils, though twice seen 
on sand. Usually scarce. 
Cirsium arvense (Carduus arvensis). By far the most common of all 
weeds. Ubiquitous among all crops and on all soils. Frequently dominant.
