INDIVIDUAL SPECIES, 39 
Anthyllis Vulneraria. 
This plant is not indigenous to this farm, but, as shown by 
Table I., the seed has often been included in seeds-mixtures in 
recent years. It was first introduced on Area 2 in 1908, but at 
the rate of only fb. per acre. On this area rare plants were to be 
found up to 24 years, but on Areas 1 and 2, where it was also 
sown, it was not found after 14 years. 
On Area 6, it gave remarkable results in the hay crop at 
1} years from a seeding of 2lb. per acre, but it had almost 
completely disappeared at 24 years except on the thinnest soil, 
and even here it was not recorded in P.c. fr. examinations at 44 
years and subsequently, nor in the Sp. fr. examination at 54 years. 
It also developed fairly well up to 14 years on Area 7, but it then 
disappeared, and was not recorded in the detailed examinations of 
this area, 
Medicago sativa (Exotic). 
This was sown on Areas 6 and 7, but it made a very poor 
development, and was not recorded in the examinations. 
Medicago lupulina (Exotic). 
This was sown on Area 5, but was not recorded in the Sp. fr. 
examination at 10} years. 
Trifolium dubium (Not sown). 
The seed of this plant has never been intentionally sown on 
the farm, but it often occurs as an impurity in seed sarnples of 
Trifolium repens and TJ. hybridum (8), (II). The plant is some- 
times plentiful in a well-manvred permanent hay field on the 
farm, but otherwise it is not very noticeable. 
On the present areas its highest P.c. fr. was 2-6 on Area 6 at 
6} years, but by the following year its P.c. fr. on this area was 
only o-g. Its highest Sp. fr. was 4 on Area 1 at 4 years, and on 
Area 6 at 54 years. 
Lathyrus sp, (Not sown). 
Traces of this genus were found on Area 2 at 6}, 74, 84 and 
gd years, but it was not otherwise recorded,
