n = number of plants sampled.
No. of genotypes = number of different genotypes [based on thresholds of 0 (100 % matching bands) and thresholds 1–4 which indicate the maximum genetic distance that is allowed between two individuals to still be clone-mates with the same multilocus genotype]. The size of the clone network is given in parenthesis as the number of clone-mate plants.
Private bands = the number of bands unique to the population; P% = percentage of bands that were variable within populations; G/N = proportion of distinguishable genotypes; I = Shannon's Information Index; D = Simpson's Diversity Index; E = Genotypic evenness measure of Fager.
Populations: Cascade (Cas) neighbourhood 1 and 2, Cascade Walk (CasW) neighbourhood 3, Mulligan's Hut (Mull) neighbourhoods 4 and 5.
SI = plants are self-incompatible; sterile = flowers male and female sterile.
