Black Wattle

Callicoma serratifolia

“A large spreading shrub ( usually about 4-5m high but can be 10-15m high ) with wattle like flowers” – NPOS p.157

Black wattle is not an Acacia so it’s not a true wattle. It got the name because it’s flowers are similar to the flowers common to wattle trees. The first wattle and daub houses in the colony of NSW were made from the branches and timber of the black wattle.

Leech

Gnatbobdellida libbata

When it’s been raining we get leeches. Jess spotted this one stuck to the underside of her table. From the description on the Australian Museum Leech page this Leech is classified as a “jawed leech” being in the Gnatbobdellida group:

“The jawed leeches or Gnatbobdellida have jaws armed with teeth with which they bite the host. The blood is prevented from clotting by production of a non-enzymatic secretion called hirudin. The land leech commonly encountered by bushwalkers is included in this group.”

The most common species in this group is the Gnatbobdellida libbata, with my 15 minutes of leech identification expertise I reckon that’s what this fella is.

Fishbone Fern

Nephrolepis cordifolia

“A fern with narrow erect fronds, often spreading over large areas.” NPOS p.310

Everyone except me ( neighbors, mum ) seemed to know all about the fishbone fern. Even though it’s a native to Australia where it naturally occurs in Queensland and Northern NSW, it’s considered a weed in Sydney. It does tend to take over parts of the garden, especially places I’ve cleared of other weeds.

The plant sketches in NPOS are usually very good, but for the Fishbone Fern I didn’t think it looked like the plant I saw. I checked a few other sources to make sure I had the right plant.

I’ll be cutting this back in the garden.

Prickly Moses

Acacia ulicifolia

“A wiry, prickly shrub to about 1.5m high…” – NPOS – p.67

I didn’t know what this was when I took the photo, it stood out because there appeared to be two very different types of flower growing on the same plant. It turned out to be two similar looking plants that were intertwined. I still don’t know what the 2nd plant is.

After seeing a plaque at the wildflower garden I’m pretty sure this is a Prickly Moses, one of the many species of Wattle.

Interesting thing about many Wattles, including the Prickly Moses, is they don’t have true leaves. The green leaf like structures are actually the leaf stalks or phyllodes. The leaves themselves have disappeared in many Australian Acacias as an adaption to our hot dry climate.
