NOTES TO TABLE III.
(1) These plants are in the highest degree invasive.
(2) These are seldom invasive, and yet widely and rather
uniformly distributed.
(3) These, though locally invasive, appear to have little
power of dissemination. They occur often in clusters.
(4) These, from some cause or other, will not often re-
establish themselves when once removed. All are probably
diminishing.
(5) The case of the Primrose is peculiar at Felstead. On the
north side of the parish it is extinct, in consequence of its
proximity to an allied species (P. elatior), which somehow acts
detrimentally. On the south side of the parish it occurs in
great profusion and seeds readily. At an intermediate point it
occurs as a lingerer. The tendency within the last fifty years
has been to remove this point still further to the south.
