Common questions
Why do forensic botanists usually report identification at family, genus, or species rather than a finer level?+
Diagnostic morphological or genetic features available from trace plant material, such as a seed fragment or pollen grain, often only support confident identification to genus or species, and subspecies-level distinctions typically require more complete material or genetic data than a trace sample provides.
What happens when a plant fragment can only be identified to a higher taxon, such as family?+
The examiner reports the identification at the level the evidence actually supports and states the limitation explicitly, since overstating precision, for example claiming a species match from features that only distinguish family, would misrepresent the strength of the evidence.
