Aquatic Macrophyte
Definition
Vascular aquatic plants, including submerged, floating, and emergent species such as Elodea, Potamogeton, Phragmites, and Nymphaea. Fragments of these plants on a body or vehicle indicate the entry point was in or near a vegetated water margin and can narrow the habitat type.

Common questions
How is macrophyte evidence different from diatom evidence in a drowning case?+
Diatoms are microscopic algae that can enter the bloodstream and internal organs and speak to whether drowning occurred in that water body, while macrophytes are visible plant fragments caught on clothing, hair, or a vehicle that place the scene near a specific type of vegetated margin rather than confirm drowning itself.
Can macrophyte fragments help distinguish between water bodies?+
Yes, because species composition varies with water depth, flow, salinity, and region, so matching the fragment species to known flora at a candidate site can narrow or corroborate a recovery location.
