Small Leaved Privet

By: Michael Fox

Discriminating between environmental weeds and similar looking native species can be difficult at times:

Chinese privet (Ligustrum sinense) may also be confused with native privet (Ligustrum australianum), which is present in northern and central Queensland. Native privet is not a pest plant. (Queensland Department of Agriculture and Fisheries)

Working at Roly Chapman Reserve Bushcare with Liz and Marshal, I was confident we were dealing with a grove of Small Leaved Privet but to be sure I Googled the Ag and Fisheries site.

The description matched except for “Deep-green finely hairy leaves”. Deep-green was right but the leaves looked smooth not hairy.

Liz and I had both watched Todd Sampson’s Redesign My Brain on ABC the night before. In the series Todd works with Dr. Michael Merzenich, Chief Scientific Officer, Posit Science, to explore brain training. Our sense of touch was one area explored in the program so Liz and I decided to experiment with our sense of touch to detect fine hairs we could not see.

Running our fingers then thumbs over the leaves we could feel the “finely hairy” even though we could not see it. Apparently we have 3,000 touch receptors or neurons in each finger tip. However, we lose neurons as we age reducing our touch sensitivity. Brain training can help compensate for the loss of neurons. Interestingly both Liz and I found that, like Todd, our thumbs were more sensitive to touch.

To actually see the fine hairs on the Privet leaf I had to take a macro-photo with my iPhone and AlloClip adapter. Click on photo to enlarge further.
