Cypress Pines, an Australian Tree

Cypress Pines are a conifer tree native to Australia. In Central NSW where I grew up they are one of the most common trees. A big old pine tree was my favourite climbing tree when I was a kid!

When young Cypress pines have a traditional triangular Christmas tree shape

When they are much older Cypress pines develop into a different shape, with the branches extending horizontally

The cones of Cypress pines are small and open fully unlike the layered cones of other pines.

Cypress Pine needles are fine and segmented.

The timber from Cypress pines is prized for its ability to resist termite attack and its atrractive knots which add interest to its grain.

Callistemon trees are called Bottlebrush because because they’re flowers look like the brushes used to clean bottles. They’re flowering now. They’re beautiful and the only feature which distinguishes a Bottlebrush flower from a bottle brush are their beautiful flowers.

The trees come in a variety of sizes from low bushes to small shrubs to small trees. They’re found naturally mostly on the Eastern seaboard of Australia, with some in New Caledonia. And they’ve been transplanted all over the world, popularly used as garden plantings because of their gorgeous blossoms.

Acacia trees are commonly called wattle in Australia. Elsewhere in the world, they’re called Mimosa.

There are over 300 species, of different sizes, shapes and types  of leaves but they all have similar flowers, with hundreds of male anthers bearing pollen which form balls or cylinders. The female stigmas are usually not able to be distinguished They vary in colour from white to deep yellow.

Grevillea plants are an Australian genus of plant which has species from ground cover bushes to trees which grow up to 30m tall. Their size, shape and types of leaves vary widely but their flowers are all of the same form. The flowers have no petals but the other structures are coloured ranging from yellow, orange, red, pink and white.

Because of their appearance sometimes grevillea flowers are called spider flowers

Grevillea flowers grow in groups called a raceme

Silky Oak trees are the largest species of the Grevillea genus

Individual Grevillea flowers can be seen here. The long stalk like structures are the female stigma and style. The male anthers are enclosed in the lower bulbous structure.
