Beacon Hill - Endemics - 14 December 2023

It was wonderful to have old familiar faces join us to botanise and from Beacon Hill we drove to Panpack and began our excursion from there.  It was to be a day filled with endemics.  

We came across Chironia albiflora which is a rare herb growing on the forest margin.  The name "Chironia" is named after Chiron, a centaur who studied medicine, astronomy and arts.

As we entered into the gully just below the dam, we found Anemone brevistylis.In Greek the word anemos meands wind and was named after the nymph Anemone who was turned into a flower by a jealous goddess, and forever buffeted by the north wind.  In Latin brevis means "short"and stylis refers to "style".  Anemones thrive in exposed windy places, their preferred habitat.
