Not many Australian plants are deciduous, but this one is bare of leaves from June to September.

It can grow to about 9m in height, but on the islands, or the coast as here, it’s usually wind-pruned to a much shorter maximum height.

Here’s another one from Karnup.
The species is apparently endemic to Australia, but records are so scarce for the two species in the genus that that may not be accurate. Nothing is known about the larvae.

An annual herb sometimes as much as 90cm tall, but usually much less. It originated in southern Europe and the Mediterranean Basin, but is now widespread and sometimes weedy.

It grows to about a meter and half tall, and dies off at the end of the season. It was introduced to Australia as a hardy, nitrogen-fixing forage crop, despite being somewhat poisonous, and rapidly became a problem.

The seeds are formed with a fatty growth on one end, so they will be collected by ants, dragged to their nests, and dumped in the fertile soil of the ant’s garbage heap after they’re eaten the bait.

Quite variable in size and colour, sometimes reaching 12m in height, and sometimes reddish-purple or bronze in colour. Some of that variation is due to selective breeding. Some cultivars are grown as ornamentals, but others are used for oil production.

Under optimal conditions, a duckweed farm can produce 10 to 30 tons of dried duckweed per hectare per year. They’ve also been genetically engineered to produce pharmaceuticals.
Tomato Lake, Belmont, Perth. Believe me, the duckweed isn’t NEARLY as big a problem as the Salvinia was.

They can rapidly multiple to fill still waterways, but they are also useful in bioremidiation of polluted waterways, and dried duckweed meal is a good quality cattle feed.

B. lutea is easily the most abundant species throughout Australia. Often found cohabiting with termites under stones or rotting logs, and preying on the latter. Also common in suburban areas, where they not infrequently sting people.

‘Yellow short wrinkled ant’.
A de-alate queen looking for a good spot to start a nest after her nuptial flight. This species has unusually large queens for Ponerine standards, and they are immediately recognisable by their size.

It can reach 2m in height but most of that is the leaves, since it doesn’t have a visible trunk, unlike the better-known species of grasstree. Like the other grasstrees, the flowerspike is a very rich source of nectar and pollen.
