Abstract

It is well known statistically that outlying values of independent variables contribute disproportionately to the fitting of a regression line. A previous examination of the environmental determinants of numbers of plant species in the British Isles includes one such outlier, Britain itself. Analyses identical to those previously performed are reported here, excluding Britain. Without the outlier, the prior conclusion that environmental heterogeneity contributes to floristic richness is unsupported.
