Polygonum lapathifolium

KINGDOM: Plantae » Class: Magnoliopsida » Order: Polygonales » Family: Polygonaceae

Polygonum lapathifolium
Morphology and biology. The stem
is straight (30-60 cm, rarely up to 1 m), branched. Leaves are linear, rarely
oval or oblong (4-40 cm). The Inflorescence - up to 4 cm long and 1.5 cm
thick. Fruit - Nut as 2.5-3.5 x 1.0 x 2.0 mm. having a smooth shiny surface.

Phlomis tuberosa

KINGDOM: Plantae » Class: Magnoliopsida » Order: Lamiales » Family: Lamiaceae

Phlomis tuberosaNamed for the small tubers that
grow from its roots, this selection is perhaps the most unusual of all. Fuzzy
leaf stems and large green leaves with toothed margins give the plant a
coarse texture that is softened by lilac blossoms with reddish calyxes and
deep crimson flower stems. Such distinctive character mixes especially well
with grasses and Lavenders.

Blooms JuneAugust.

Size: 4' high x 3' wide; hardy to zone 6.

Melandrium album

KINGDOM: Plantae » Class: Magnoliopsida » Order: Caryophyllales » Family: Caryophyllaceae

Melandrium albumSoftly-haired weed with deep,
fleshy root, sometimes with root buds. Stem is erect, hairy, usually ramified
from the base up, 30-100 cm high. Cotyledons are ovate acuminate, gradually
tapering into the petiole. Foliage leaves are in opposite pairs, lower leaves
inverse ovate and petiolate, upper leaves lanceolate and sessile, haired at
the margin and on the veins. Flowers are unisexual, dioecious, in
paniculiform inflorescences, white, fragrant, loosely arranged. Calyx is
15-20 mm long, with 10-20 ribs, does not open until afternoon. Boll opens
with 10 teeth. Seeds are small, 1-1.5 mm long, dark-brown. Shoots emerge in
spring, shallow germination. Flowering period - June - August. The mass of
1000 seeds is 0.5-0.7 g. Seeds per plant : about 6000. Can propagate with
root layers as well.

Melampyrum arvense

KINGDOM: Plantae » Class: Magnoliopsida » Order: Scrophulariales » Family: Scrophulariaceae

Melampyrum arvense
This annual plant is
hemi-parasitic , this means that its roots attach to those of other plants
and it is able to obtain some nutrition from them. Plants grown in the
absence of a host fail to thrive. A wide range of plants can be used as
hosts, especially grasses. Field cow-wheat flowers from June to September,
the flowers being pollinated by bumblebees . The heavy seeds are poor
dispersers and can stay dormant in the soil for about two years . They have a
small oil body at one end, which is attractive to ants, who may carry the
seeds to their nests, eat the oil body then discard the seed . By doing so
they aid in the dispersal of the plant. The seeds are unusual in that they
germinate in the autumn, and the roots develop well before the shoots (which
develop in the spring); presumably this is so that the seedlings can attach
themselves to the roots of host plants quite quickly .

Melampyrum arvense

KINGDOM: Plantae » Class: Magnoliopsida » Order: Scrophulariales » Family: Scrophulariaceae

Melampyrum arvense
This colourful endangered plant
has pale green, toothed and narrow leaves that grow on opposite sides of the
stem. The flowers grow in a spike known as an inflorescence, and are
generally purplish-pink in colour with a yellow throat and lip. Long, thin bracts
also emerge from the flower spike; these can be green, deep pink or white in
colour. A local name for this species is 'poverty weed' as the seeds gave a
bad taste to flour and devalued the price of corn.

Medicago lupulina

KINGDOM: Plantae » Class: Magnoliopsida » Order: Fabales » Family: Fabaceae

Medicago lupulina
Annual with prostrate or
ascending stems up to 2½' long. These stems are light green or reddish
green and densely covered with white hairs (although older stems become less
hairy); they branch occasionally. The alternate compound leaves are trifoliate.
Young trifoliate leaves toward the tips of the stems have short hairy
petioles, while older trifoliate leaves have longer petioles. At the base of
each petiole, there is a pair of stipules that are lanceolate to ovate and
variable in size. The leaflets of the compound leaves are up to 2/3"
long and about half as much across; they are medium to dark green, obovate or
oval-ovate, hairy or nearly hairless, and slightly dentate along their
margins. Each middle leaflet has a short stalk, while the lateral leaflets
are sessile. The upper surface of each leaflet has fine lateral veins that
are light green and straight.

Lythrum salicaria

KINGDOM: Plantae » Class: Magnoliopsida » Order: Myrtales » Family: Lythraceae

Lythrum salicarialanceolate, 3-10 cm long and
5-15 mm broad, downy and sessile, and arranged opposite or in whorls of
three.

The flowers are reddish purple, 10-20 mm diameter, with six petals
(occasionally five) and 12 stamens, and are clustered tightly in the axils of
bracts or leaves; there are three different flower types, with the stamens
and style of different lengths, short, medium or long; each flower type can
only be pollinated by one of the other types, not the same type, thus
ensuring cross-pollination between different plants.

The fruit is a small 3-4 mm capsule containing numerous minute seeds.
Flowering lasts throughout the summer. When the seeds are mature, the leaves
often turn bright red through dehydration in early autumn; the red colour may
last for almost two weeks. The dead stalks from previous growing seasons are
brown.

L. salicaria is very variable in leaf shape and degree of hairiness, and a
number of subspecies and varieties have been described, but it is now
generally regarded as monotypic with none of these variants being considered
of botanical significance. The species Lythrum intermedium Ledeb. ex Colla is
also now considered synonymous.

Lepidium ruderale

KINGDOM: Plantae » Class: Magnoliopsida » Order: Capparales » Family: Brassicaceae

Lepidium ruderale
Annual or biennial, more or less
foetid, 20-30 cm, single-stemmed, much branched above, glabrous or sparsely
covered with short spreading hairs. Basal leaves 2-3 x pinnate,
long-petiolate, forming a loose rosette or withering early. Caulline leaves
pinnate with narrow entire segments; upper segments narrow, oblong, sessile.
Fruiting pedicels slender, ascending, 2-4 mm. Siliculae ovate or broadly
elliptical, narrowly winged above, 2-2.5 x 1.5-2 mm; septum 1.5-2 x 0.5
mm.

Leonurus cardiaca L.

KINGDOM: Plantae » Class: Magnoliopsida » Order: Lamiales » Family: Lamiaceae

Leonurus cardiaca L.
L. cardiaca has a square stem
and opposite leaves. The leaves have serrated margins and are palmately lobed
with long petioles; basal leaves are wedge shaped with three points and while
the upper leaves are more latticed. Flowers appear in leaf axils on the upper
part of the plant and it blooms between June - August. The flowers are small,
pink to lilac in colour often with furry lower lips. The plant grows to about
60-100 cm in . It can be found along roadsides and in vacant fields and
other disturbed areas.

Inula helenium

KINGDOM: Plantae » Class: Magnoliopsida » Order: Asterales » Family: Asteraceae

Inula heleniumIt is a rather rigid herb, the
stem of which attains a of from 3 to 5 feet; the leaves are large and
toothed, the lower ones stalked, the rest embracing the stem; the flowers are
yellow, 2 inches broad, and have many rays, each three-notched at the
extremity. The root is thick, branching and mucilaginous, and has a warm,
