11th April 2026 - Adeline Park, Faulconbridge

A well-attended walk with 15 members on a sunny autumn day exploring the ridgetop woodland of Adeline Park, part of the Linden Creek Catchment.

Of particular interest on this walk was Eucalyptus burgessiana (Faulconbridge Mallee Ash), whose type specimen was collected here by Laurie Johnson of the Royal Botanic Gardens and Rev. Colin Burgess in 1953. (Burgess was rector of St Albans Leura, 1944-56 and in 1963 wrote the local handbook Blue Mountains Gums. He later worked as a botanist at the Australian National Botanic Gardens.)

In flower we saw Hakea propinqua, Pultenaea tuberculata, Leucopogon microphyllus, Banksia spinulosa, Platysace linearifolia, Bossiaea heterophylla, Woollsia pungens, Lepyrodia scariosa, Actinotus helianthi and A. minor. The prolific Acacia oxycedrus which we saw in bud will be a delight in Spring.

Two heath myrtles, Harmogia densifolia and Baeckea brevifolia, growing side by side, caused initial confusion, sorted by closer observation and consultation of our floras.

14th March 2026 - Coates Park, Hazelbrook

A sunny autumn day raised group expectations in finding a good diversity of plants in Coates Park. At the start of the track we did tuck our long pants into our socks to protect ourselves from any hungry leeches! Then we stayed on a narrow track through swamp surrounded by the large dominant rush, Schoenus melanostachys.

Coates Park is a council reserve, with protected vegetation under the Local Environment Plan 2015 i.e., B.M. Heath & Scrub and B.M. Swamps being present. Also, council mapping shows Corymbia gummifera and Eucalyptus sieberi Open Forest as being present. Additional Eucalypts formed the open canopy for vigorous Proteaceae shrubs such as the Persoonia species.

Persoonia acerosa was a plant of interest, as it is a rare and listed Endangered species. It has very narrow leaves, acerosa, coming from the Latin acerosus meaning ‘needle-shaped’. The plants are killed by fire and recruitment is only from seed. So hazard reduction and bushfire are one of its threats.

It was a delight to see orchid leaves emerging beside the track. We ate our lunch sitting on a log, surrounded by a splendid diversity of plants and then returned back along the track

14 February 2026 - Fairfax Heritage walk, Blackheath

Nine members arrived at the Blue Mountains Heritage Centre in wet and misty conditions. We watched some audiovisual displays in the Auditorium, visited the bookshop and set off on our walk when the weather improved a little.

The track, which was constructed in the mid 1980s, goes to Govetts Leap lookout via a woodland dominated by Eucalyptus piperita, E. sieberi and E. racemosa ssp. racemosa. Also at the site is E. radiata.

The shrub and herb layers of the woodland are very diverse. We particularly noted Daviesia ulicifolia, Gahnia clarkei, Grevillea laurifolia, Haemodorum planifolium, Hakea teretifolia, Persoonia myrtilloides, Polyscias sambucifolia and Acacia rubida. The latter is unusual in that some bipinnate juvenile leaves persist on the plant, as evident in the photo. Most species of Acacia with phyllodes (modified stems) have no juvenile leaves beyond the seedling stage.

Along the way, there were some good-humoured disputes about the pronunciation of botanical names. Should the “c” in ericifolia be hard or soft? Ought we to say “Lambert-ee-a” to properly honour Mr Lambert instead of the usual “Lambersha”? Things got too serious when the discussion turned to the French “au” in the name of botanist Gaudichaud-Beaupré and the Latin “au” in the name of the new tea tree genus Gaudium – at which point we wisely abandoned the subject altogether!

28 January 2026 - Blue Mountains Botanic Garden

This outing was a mid-week bus trip. Ashley Filipovski, the Curator Manager of the Blue Mountains Botanic Garden Mount Tomah, took us on an extensive tour of the botanic garden itself and the tall wet forest juxtaposed with it. Both areas have superb plant assemblages, with the magnificent Eucalyptus fastigata Brown Barrel as the dominant species.

Another common tree in the native forest is Doryphora sassafras Sassafras, the tree in the photo. The ten or so ring of trunks in the foreground are all the same ancient tree. There was once a massive trunk at the centre of the ring, and the younger trunks grew from the periphery of its root system.

Ash provided expert commentary on the increasing role of the garden in nature conservation, the ongoing installation of a sprinkler system to protect against bushfires, the differences between French and English formal gardens, and other topics. All in all, the outing was very enjoyable and educational.
