Frequency distribution of lithium in leaves of Lycium andersonii

Lvcium andersonii A. Gray is an accumulator of Li. Assays were made of 200 samples of it collected from six different locations within the Northern Mojave Desert. Mean concentrations of Li varied from location to location and tended not to follow loge normal distribution, and to follow a normal distribution only poorly. There was some negative skewness tp the loge distribution which did exist. The results imply that the variation in accumulation of Li depends upon native supply of Li. Possibly the Li supply and the ability of L. andersonii plants to accumulate it are both loge normally distributed. The mean leaf concentration of Li in all locations was 29 μg/g, but the maximum was 166 μg/g.
