Abstract
Field studies of fruit production from Lepidosperma concavum R.Br., L. laterale R.Br. and L. longitudinale Labill. showed that large proportions (21-77%) of fruits were unfilled and that filled and unfilled fruits looked alike. Bagging of inflorescences demonstrated that filled fruits tended to be shed, while empty fruits remained within the inflorescence. Time of collection was critical for obtaining viable seeds, with successful harvesting limited to a short period (weeks) after maturation. The timing of flowering and fruit maturation were fairly consistent between species, populations and years in our study area. In L. concavum fruit production was increased in cultivation compared with w..
