The effect of plant size on reproductive characteristics was examined in a natural population of Erythronium americanum Ker. The number of ovules, fertilized ovules, unfertilized ovules, aborted seeds, and seeds and the fruit weight were found to be correlated positively with plant weight. Only 35% of the available ovules per plant were fertilized and 24% became seeds. Despite the low rate of ovule fertilization, nearly one-third of the fertilized ovules aborted before maturing into seeds. The majority of plant biomass was placed into nonsexual stuctures and, of these, the corm accounted for 60% of the dry weight, leaves 21%, and stem 12%. The remaining 7% was allocated to sexual structures.
