Overview

Observational study demonstrates that microscopic pollen and bracteole features accurately identify cattail taxa in a hybrid zone, suggesting a low-cost tool for managing invasive wetland hybrids.

Key Points

  • To evaluate whether microscopic reproductive characteristics, specifically pollen and bracteole traits, can accurately distinguish parental cattail species from complex interspecific hybrids.
  • Assessed microscopic pollen and floral bracteole traits in flowering cattail specimens collected across an admixed North American hybrid zone.
  • Compared microscopic morphological identifications directly against genotype-based taxonomic assignments.
  • Microscopic pollen traits accurately matched genotype-based taxonomic assignments in 96% (409/426) of assessed plants.
  • Microscopic bracteole traits matched genotype assignments in 95% (232/244) of plants, with advanced-generation non-F1 hybrids accounting for most classification errors.
