AUSTRALIAN WATER DRAGON

The Australian water dragon (Intellagama lesueurii), which includes the eastern water dragon (Intellagama lesueurii lesueurii) and the Gippsland water dragon (Intellagama lesueurii howittii) subspecies, is an arboreal agamid species native to eastern Australia from Victoria northwards to Queensland. There may be a small introduced population on the south-east coast of South Australia.

The Gippsland water dragon is generally the more southern of the two subspecies and the more cold adapted and heat sensitive. Visually distinguishing the Gippsland water dragon from the Eastern water dragon is relatively easy, as long as their skin is reasonably clean and not stained from the water, as identification of the two subspecies depends largely on observable differences in colours and patterns.

Australian water dragons have long powerful limbs and claws for climbing, a long muscular laterally-compressed tail for swimming, and prominent nuchal and vertebral crests (a nuchal crest is a central row of spikes at the base of the head. These spikes continue down the spine, getting smaller as they reach the base of the tail).

Including their tails, which comprise about two-thirds of their total length, adult females grow to about 60 cm long, and adult males can grow slightly longer than one metre and weigh about 1 kg. Males show bolder colouration and have larger heads than females. Colour is less distinct in juveniles.

The Australian water dragon's diet depends on its size. Juveniles and yearlings tend to feed on spiders and small insects such as ants, crickets, and caterpillars. When they get bigger, so does their prey. An adult diet includes small rodents, such as baby mice, other reptiles, frogs, fish, crabs, yabbies, molluscs, worms and eggs, although insects are still the most commonly consumed. Types of vegetation reportedly consumed include figs, lilly-pilly fruits, berries, and other fruits and flowers.

SCAEVOLA

Scaevola is a genus of flowering plants in the Goodenia family, Goodeniaceae. It consists of more than 130 tropical species, with the centre of diversity being Australia and Polynesia. Common names for Scaevola species include scaevolas, fan-flowers, half-flowers, and naupaka, the fan flower's Hawaiian name. The flowers are shaped as if they have been cut in half. The generic name means "left-handed" in Latin.

Many legends have been told to explain the formation of the naupaka's unique half flowers. In one version a woman tears the flower in half after a quarrel with her lover. The gods, angered, turn all naupaka flowers into half flowers and the two lovers remain separated while the man is destined to search in vain for another whole flower.

Scaevola is the only Goodeniaceae genus that is widespread outside of Australia. In at least six separate dispersals, about 40 species have spread throughout the Pacific Basin, with a few reaching the tropical coasts of the Atlantic and Indian Oceans. The Hawaiian Islands are home to ten Scaevola species, nine of which are endemic. Eight of the indigenous species are the result of a single colonisation event.

Scaevola aemula (Fairy Fan-flower or Common Fan-flower, shown here) is a small shrub native to southern Australia. It grows to 50 cm in height and produces white or blue flowers in spikes up to 24 cm long from August to March in its native range. These are followed by rounded, wrinkled berries to 4.5 mm in length. The species occurs in Western Australia, South Australia, Victoria and New South Wales.

The species is thought to be the most commonly cultivated of the genus Scaevola, and a large number of cultivars have been developed. Most of these are mat-forming to a height of 12 cm and spreading up to 1 metre in width. It prefers a sunny or partially shaded, well-drained position and tolerates salt spray and periods of drought. Pruning and pinching of tip growth may be carried out to shape the plant. Propagation is from cuttings or by layering.

ALMA MATER

On the City Campus of the University of Melbourne. Despite the large number of new buildings that have gone up since I was a student there, it was heartening to discover that some green spaces have remained and little nooks such as this one have hardly changed at all.

YARRA VALLEY VIEW

The Yarra Valley is the name given to the region surrounding the Yarra River in Victoria, Australia. The river originates approximately 90 kilometres east of the City of Melbourne and flows towards it and out into Port Phillip Bay. The name Yarra Valley is usually used in reference to the upper regions surrounding the Yarra River and generally does not encompass the lower regions including the city and suburban areas, where the topography flattens out, or the upper reaches which are in inaccessible bushland.

Included in the Yarra Valley is the sub-region of Upper Yarra (or the Upper Yarra Valley) which encompasses the towns of the former Shire of Upper Yarra in the catchment area upstream of and including Woori Yallock. The Yarra Valley a popular day-trip and tourist area, featuring a range of natural features and agricultural produce, as well as the Lilydale to Warburton Rail Trail.The Yarra Valley is host to a thriving wine growing industry.

The area's relatively cool climate makes it particularly suited to the production of high-quality chardonnay, pinot noir and sparkling wine. Vine-grazing is a popular activity for Melburnians and there is a large selection of excellent vineyards making world-class wines in the Yarra Valley.

POSSUMS

The common brushtail possum (Trichosurus vulpecula, from the Greek for "furry tailed" and the Latin for "little fox", previously in the genus Phalangista) is a nocturnal, semi-arboreal marsupial of the family Phalangeridae, it is native to Australia, and the second largest of the possums.  Like most possums, the common brushtail possum is nocturnal. It is mainly a folivore, but has been known to eat small mammals such as rats.

In most Australian habitats, leaves of eucalyptus are a significant part of the diet but rarely the sole item eaten. The tail is prehensile and naked on its lower underside. There are four colour variations: silver-grey, brown, black, and gold.  It is the Australian marsupial most often seen by city-dwellers, as it is one of few that thrives in cities, as well as a wide range of natural and human-modified environments. Around human habitations, common brushtails are inventive and determined foragers with a liking for fruit trees, vegetable gardens, and kitchen raids.

SUMMER IS ON ITS WAY

We had a maximum temperature of 36˚C today, which was a little uncomfortable, especially as it was quite high after the few 20s and mid 20s we'd had previously. The sunset turned out to be quite summery too...

HIPPEASTRUM

Hippeastrum flowering in our garden. Hippeastrum is a genus in the family Amaryllidaceae. The name Hippeastrum, given to it by William Herbert, means "knight's star", although precisely what Herbert meant by the name is not certain.

For many years there was confusion among botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name amaryllis is mainly used for cultivars of this genus, often sold as indoor flowering bulbs particularly at Christmas in the northern hemisphere.

By contrast the generic name Amaryllis applies to bulbs from South Africa, usually grown outdoors. The genus is native to tropical and subtropical regions of the Americas from Argentina north to Mexico and the Caribbean.
