We investigated whole-plant leaf area in relation to ontogenetic variation in leaf-size for a forest perennial herb, Cardiocrinum cordatum.The 200-fold ontogenetic variability in C.cordatum leaf area followed a power-law dependence on total leaf number, a measure of developmental stage.

When we normalized for plant size, 2014 dodge ram 1500 fender flares the function describing the size of single leaves along the stem was similar among different-sized plants, implying that the caruso rhodiola different-sized canopies observed at different times in the growth trajectory were fundamentally similar to each other.We conclude that the growth trajectory of a population of C.cordatum plant leaves obeyed a dynamic scaling law, the first reported for a growth trajectory at the whole-plant level.
