Typha latifolia, called tábua-larga in Flora-On, occurs in ditches, ponds, lakes and slow-flowing watercourses. The profile highlights soils waterlogged for much of the year. It gives a floral feature for confirming the species: the male and female inflorescences touch. This general description confirms neither a population in the municipality nor an identification of a particular plant.
Lentic is the term for still or slow-moving water. That clue concerns the environment; the positions of the two flower clusters concern the plant. Separating the questions improves observation: what is the water like, and which structures can I distinguish? A damp ditch alone does not confirm the species, just as an isolated stem does not describe the whole environment.
Flora-On mentions fresh or slightly mineralised water and a preference for base-rich substrates. It adds that higher phosphorus concentrations in water can favour the plant. This is an ecological relationship described for the species; seeing a cattail cannot replace nutrient measurements or prove that a discharge has occurred.
Comparison with rush helps distinguish habitats: a damp meadow and waterlogged ground beside slow water are not identical descriptions. The diagram in this story offers a way to explore those differences.

The large board finds conditions in ditches, ponds and slow watercourses, with soaking soils during much of the year.
In the description of the species, the sets of male and female flowers are leaned against.
Wet wood · look at the vegetation
The water-blood can grow in forests and margin shrubs, hedges and under coals, in humid places.
