Abstract
The occurrence of gynodioecy in two populations in northern England of the normally hermaphroditeSaxifraga granulata is reported. Female plants have aborted stamens, and smaller petals than hermaphrodites. At Staindrop, County Durham, an estimated 23% of the flowering stems were female; at Macclesfield, Cheshire, 4% were female. The inheritance of male sterility is not simple, and probably involves at least one cytoplasmic and two nuclear genes. The secondary sexual characteristics, hermaphrodite-predominant sex ratios, and complex inheritance of male sterility, are typical of gynodioecious populations.
