AUSTRALASIAN GREBE

The Australasian grebe (Tachybaptus novaehollandiae) is a small waterbird common on fresh water lakes and rivers in greater Australia, New Zealand and on nearby Pacific islands. At 25–27 cm in length, it is one of the smallest members of the grebe family, along with the least grebe and little grebe.

The Australasian grebe is common on fresh water ponds and small rivers or lakes throughout most of Australia, New Zealand and on the nearby islands. They eat small fish and aquatic insects. In winter, adult birds have dark greyish-brown upperparts and mostly silvery-grey underparts and a white oval patch of bare skin at the base of the bill when in non-breeding plumage. Breeding plumage is considerably brighter: the head is glossy-black with a rufous or chestnut stripe that extends from just behind the eye to the base of the neck, the eye is gold and the patch of bare skin at the base of the bill is pale yellow. Males and females look the same.

When breeding, grebes conceal their floating nests amongst reeds on the surface of the water. The chicks can swim at birth. A peculiar habit that grebes have is they eat their feathers and feed them to their young. Although it is not known with certainty why they do this, several hypotheses have been proposed, including; to prevent injury from swallowed fish bones; to assist with pellet formation; and to reduce their vulnerability to gastric parasites.

CHRISTMAS BUSH

Ceratopetalum gummiferum, the New South Wales Christmas Bush, is a tall shrub or small tree popular in cultivation due to its sepals that turn bright red-pink at around Christmas time. The petals are actually small and white - it is the sepals that enlarge to about 12mm after the flower sets fruit and starts to dry out. The specific name gummiferum alludes to the large amounts of gum that is discharged from cut bark.

Plants initially grow as rounded shrubs but mature to pyramidical trees. The leaves comprise three leaflets and are up to 8 cm long. The petioles are grooved on the upper side and are 10 to 20 mm long. Small, white five-petalled flowers appear in spays from October in the species native range. As these die the sepals enlarge and become pink to red in colour, the display peaking at Christmas time in Australia (i.e. during Summer).

Ceratopatalum gummiferum is one of nine species in the genus Ceratopetalum int eh family Cunoniaceae, which occur in Australia and Papua New Guinea. The species was first formally described by English botanist James Edward Smith in 1793 in 'A Specimen of the Botany of New Holland'.

The species is endemic to New South Wales where it occurs to the east of the Great Dividing Range from Ulladulla in the south to Evans Head in the north. In cultivation, plants usually grow to no more than 6 metres in height. Plants may be propagated from seed or cuttings, the latter method being preferred to maintain good colour forms. Well-drained soil is required to avoid problems with dieback associated with root-rot fungus.

EDELWEISS

Leontopodium nivale, commonly called edelweiss, is a well-known mountain flower, belonging to the Asteraceae (daisy or sunflower family). The plant prefers rocky limestone places at about 1,800–3,000 metres altitude. It is non-toxic, and has been used traditionally in folk medicine as a remedy against abdominal and respiratory diseases. The dense hair appears to be an adaptation to high altitudes, protecting the plant from cold, aridity, and ultraviolet radiation.

As a scarce, short-lived flower found in remote mountain areas, the plant has been used as a symbol for alpinism, for rugged beauty and purity associated with the Alps and Carpathians, and as a national symbol, especially of Austria, Bulgaria, Romania, Slovenia, and Switzerland. According to folk tradition, giving this flower to a loved one is a promise of dedication.
