Individual leaf areas were determined by tracing a leaf onto graph paper; the area of the petiole was not included within the calculations. From each individual plant, a subsample representing three small, three medium and three large leaves were harvested, and the mean of each of the three leaves was taken and used to provide a representative small, medium and large leaf area. The number of small, medium and large leaves in each individual plant was then counted, and the corresponding areas were used to estimate the total leaf surface area. aTotal leaf area was calculated as both the upper and lower sides of the leaves. T. usneoides, a moss, was also placed within the container, but it was not possible to calculate leaf area.
