(P = 0.3), Phlox (P = 0.1) and Rosa (P = 0.3) were examined individually. We were
unable to detect an effect in Lathyrus, which flowered a little, but no single plant
went to seed. None of the plants in the study produced fruits and only three fruits
were found when the field inside and outside the fence was surveyed.

a) The relationship between seed mass and flower number for Phlox (n = 60), Rosa (n = 48) and Rhus
(n = 60) respectively.
Both seed
mass and flower number were square root transformed, b) The relationship between the residuals
(mean ± 1 SE) of seed mass versus flower number and the percent leaf removal for Phlox (n = 60), Rosa (n = 48)
and Rhus (n = 60) respectively.
The meristem removal treatment had a significantly negative effect on flower
number in both Phlox and Rosa (Figure 4a). The individuals in the meristem re-
moval treatment produced very few flowers when compared to those individuals
in the control and leaf removal treatments. Meristem removal also caused the seed
mass to be significantly lower in Rosa, though the seed masses of both Phlox and
Rhus remained unaffected (Figure 4b).
