The thin cane of swamp (Phragmites australis) is one of the most typical species of the sweet water swamp and it covers wide areas
Thin cane of swamp
large underground rhizome;
rigid culm, erected and sturdy, high average from 50 to 250 cm.;
lanceolate leaves, with acute apex and sometimes of cartilaginoid consistency.
The thin cane of swamp is a perennial plant of unmistakable aspect equipped of
Typha angustifolia
Typha, from the Greek, tufh
(typhe), perhaps from typhein,
to smoke or to emit smoke, in
allusion either to the use of the
spikes for maintaining smoky
fires or to the smoky brown
color of the fruiting spikes
angustifolia, from the Latin,
angustus, "narrow", and folius,
"leaf"; hence, "narrow leaf"
The Typha angustifolia is an erect, rhizomatous, semiaquatic or aquatic, perennial herb.
The Leaves are: erect,
linear, flat, basal, very
narrow, and flattened; 4-
12 millimeter wide and
30-60 cm. tall; 12-16
leaves arising from each
vegetative shoot.
The Stems are stout
and erect
Rhizomes stout are produced at the leafbase
Flower structure a dense, fuzzy, cylindrical spike on the end of stem. Both male and female sections are roughly the same length. Male flowers lighter brown; female flowers often green during bloom turning dark brown during seed maturation. Individual blossoms minute and closely packed on spike. Bloom May-June.
•Fruits cigar-shaped and with soft, downy seeds.
•Seed a tiny nutlet, about 1 mm long, with downy hairs underneath
The Typha angustifolia has less rhizomes but more
extended than the latifolia on, and this lead up to a
smaller colonization rate, but at the same time it
allows to grow in deeper waters.
The Tamarisk is a small tree that the height goes from the 4 to the 8 meters and is enough long-lived.
The Tamarisk
It has a expanded gait and it has long branches, erected and curved in the external way. The bark is of ash-dark color and it is smooth.
It prefers the litoral sandy lands. It blooms between June and August. The wood is semihard; it is used for small works because, it is fragile and of not long duration.
The leaves are small, simple and are thickened in little bunches, with oval form and green-glaucous colour. The flowers are small, most numerous, in racemes. The fruit is a trigonal-pyramidal capsule, that contains few seeds, with some down in the high part.
Characteristics: Erected plant with dark oblique rhizome with one centimeter of diameter and shaft and in part erect that can be long such as the leaves.
The greenish leaves
start from the base of
the plant, becoming fan-
shaped; they are of
sword shape with
prominent median
nervation ,and wide up
to 3 cm. The flowered
spathes have lower
sizes.
Every year the plant
delivers new jets from
the rhizome. The
flowers are in groups
of actinomorphic form
and have a diameter
that can surpass the
10 cm and they are of
a intense golden
yellow colour.
The external verticil is
formed by big tepals
that turn down and are
speckled with brown.
The three internal
tepals are smaller and
with a prolonged form
that goes overlook the
high.
The morphology of this flower is quite complex, being
formed by two verticils with three tepals in alternating
position.
SCHOENOPLECTUS LACUSTRIS
Lacustrine hurds
Reign:Plaint
Class:Monocotyledonous
Order:Juncales
Family:Cyperaceae
Nature:Schoenoplects
Specie:lacustris
Order:Juncales
.
Vilucchione - Calystegia sepium
Perennial from rhizomes,
trailing or climbing vine to e
metres long, with distinct
triangular leaves. The
flowers have 5 Regular Parts
and are up to 7.5cm long (3
inches). They are white
sometimes pink. Blooms first
appear in mid spring and
continue into mid summer.
Once established, it is very difficult to eradicate the plant because it has very deep roots and is capable of re-growing from any part of the root left in the ground.
The flowers open in sunny weather
and remain closed during dull
weatherThe plant prefers light
(sandy), medium (loamy) and
heavy (clay) soils. The plant
prefers acid, neutral and basic
(alkaline) soils. It can grow in
semi-shade (light woodland) or no
shade. It requires moist soil
