Abstract
Seed was collected from plants ofLobelia urens growing in three populations in southern England. Metrical measurements were made on individuals grown from sub-samples of these seeds in a common garden experiment. Electrophoresis of soluble seed proteins was also carried out. Plants from the isolated populations, growing at the northern edge of the species' range, displayed a high level of overall similarity, though some differentiation of one population appeared to have occurred. More significant variation occurred between families within populations.
