Transcript Thin cane of swamp

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
The thin cane of swamp is a perennial plant
of unmistakable aspect equipped of
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.
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; 412 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
The Tamarisk is a small tree that the height goes from
the 4 to the 8 meters and is enough long-lived.
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.
IL GIAGGIOLO
THE IRIS
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 fanshaped; 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 morphology of this flower is quite complex, being
formed by two verticils with three tepals in alternating
position.
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.
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
