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.
. 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
