CAIRNS BRANCH ..........7 1 Editor's Note - There's been ongoing debate about the status of the Emerald TABLELANDS BRANCH....7 Creek Callitris. The leaves, cones and preferred habitat differ from the usual TOWNSVILLE BRANCH....7 Callitris intratropica - notice how the Emerald Creek population grows right on the creek, where most C. intratropica grow on dry hills. The resolution to this debate awaits someone with the time and enthusiasm to sort it out. The large trees with the red leaves HEMEROCALLIDACEAE LECYTHIDIACEAE were Blepharocarya involucrigera Dianella caerulea var. vennata Planchonia careya (Rose butternut). Some Planchonia careya also presented red leaves. PANDANACEAE MALVACEAE Pandanus cookii Grewia retusifolia Hakea persiehana had produced one large capsule, Grevillea glauca POACEAE MORACEAE had many “clothes pegs” and *Melinis repens Ficus rubiginosa forma rubiginosa Ficus rubiginosa forma rubiginosa MYRTACEAE near the waterfall was in fruit. The Eudicots Corymbia erythrophloia small Phyllanthus ? [possibly Phyllanthus fuernrohrii] and ACANTHACEAE Haemodorum coccineum along the way also had many small fruits. Canarium australianum var australianum and Corymbia erythrophloia (with red and brown bark) were distinct trees on the side of the path. Red fungus adorned the branches of Sersalisia Eucalyptus crebra (narrow-leaved sericea. The falls had a good flow ironbark) in spite of the dryness of the Rostellularia adscendens Lophostemon grandiflorus surrounds. No ferns were APOCYNACEAE Melaleuca viridiflora observed.
