dc.description.abstractThis paper examines the relationship between quantitative variation in floral morphology (sizes of petals, spur and peduncle) and maternal reproductive success (seed production) in Viola cazorlensic (Violaceae), a narrowly endemic violet of south-eastern Spain pollinated by day-flying hawkmoths (Sphingidae). This plant is characterized by broad intraspecific variation in size and proportions of floral parts. Floral morphology does not influence significantly the probability of fruit set. Among flowers setting fruit, spur length and size of petals have no significant effect on seed production, but capsules from long- and short-peduncted flowers contain significantly more seeds than capsules from flowers with intermediate peduncles. Individual plants differ significantly in average floral characteristics. Plants with comparatively long and short peduncles tend to produce more seeds than those with intermediate ones, even after accounting statistically for individual differences in flower production. These findings are interpreted as evidence of disruptive selection on peduncle length during the study season. Floral variability in this species may be explained by the combined action of disruptive selection on peduncle length (the character most variable among individuals) and little, if any, stabilizing selection on spur length and size of petalses_ES
