Seeds that travel through the water
The alder has a close relationship with the rivers.

In the form of the University of Évora, published under the name Alnus glutinous, the seeds of the alder have aired tissues that favor dispersion through water. The tree tolerates prolonged periods with submerged roots. The woods in which it dominates are called amial.
The relationship with the water goes, thus, from the installation next to the banks of the journey of the seeds. There is also a change of names to know: Flora-On uses Alnus Lusitanica for Portuguese native aldermen, citing a study of 2017. Each name keeps the link here to its source; the reading does not identify a concrete tree of the municipality.
The form published as Alnus glutinous describes a caducifólia tree: it loses the foliage in a part of the year. The leaves are alternating, with double-bit margin; the peel, smooth as a young man, becomes darker and split. They are characteristics of different parts of the plant and also of different stages of its life.
The flowering indicated in this source runs from December to February. Male flowers appear in elongated groups, the amentos, while the female groups have another form. Winter can thus offer observations that a visit with the canopy full of leaves does not show. This calendar belongs to the description consulted and may vary with the conditions of the place; it does not announce the flowering of a copy of Cabeceiras.
