Măceşul (Rosa canina)
It is kind of a wild rose. It is a perennial,
thorny, branched frutex with stems, reaching
1-5 m lеnght. Rosa canina blooms in May June and its petals are pale pink to white, 4-6
cm in dm. The fruit ripe in autumn and are
oval-shaped, red-orange, 1-2 cm, pulpish, full
of plenty of hairy seeds.

Stejar (Quercus robur),
Is a large deciduous tree 25–35 m tall
(exceptionally to 50 m), with lobed and nearly
sessile (very short-stalked) leaves 7–14 cm
long. Flowering takes place in mid spring,
and their fruit, called acorns, ripen by the
following autumn. The acorns are 2–2.5 cm
long, pedunculate (having a peduncle or
acorn-stalk, 3–7 cm long) with one to four
acorns on each peduncle.

Birch ( Mesteacăn)
Birch species are generally small to medium-size trees or
shrubs, mostly of temperate climates. The simple leaves
may be toothed or pointed. The fruit is a small samara,
although the wings may be obscure in some species.
They differ from the alders (Alnus, other genus in the
family) in that the female catkins are not woody and
disintegrate at maturity, falling apart to release the
seeds, unlike the woody cone-like female alder catkins.
The bark of all birches is characteristically marked with
long horizontal lenticels, and often separates into thin
papery plates, especially upon the Paper Birch. It is
practically imperishable, due to the resinous oil which it
contains. Its decided color gives the common names
gray, white, black, silver and yellow birch to different
species.

Papura ( TIPHA)
Typha leaves are alternate and
mostly basal to a simple, jointless
stem that eventually bears the
flowering spikes. The rhizomes
spread horizontally beneath the
surface of muddy ground to start
new upright growth, and the
spread of Typha is an important
part of the process of open water
bodies being converted to
vegetated marshland and
eventually dry land.

Fir (Brad)
Firs (Abies) are a genus of 48–55
species of evergreen conifers in the
family Pinaceae. They are found
through much of Europe, occurring in
mountains over most of the range.
All are trees, reaching heights of 10–
80 m (30–260 ft) tall and trunk
diameters of 0.5–4 m (2–12 ft) when
mature. Firs can be distinguished
from other members of the pine
family by their needle-like leaves,
attached to the twig by a base that
resembles a small suction cup.
