Here's what I've got this week from An Author Bites the Dust by Arthur W. Upfield:
Mulga forests: The mulga can be a small tree up to 9 m, with a well-defined main stem and angled branches, or a shrub 2 to 5 m tall with highly angled branches. The species has a very wide distribution, from Western Australia near Shark Bay, through central Australia to mid-west Queensland and New South Wales.
Gibber flats: barren places that are covered with small stones; characteristic of the Australian Outback
Context: It is a far cry from the inland plains and mulga forests and gibber flats, swooning in the grip of the relentless sun, to the Valley of the Yarra, bright green an luscious and temperatre. (p. 22)
Verdure: The lush greenness of flourishing vegetation.
Context: So here he was a thousand miles or so from his own stamping grounds, seated at ease a few yards from a main highway instead of a winding camel pad, living in a country of flowing water and green verdure instead of flowing sand and brick-red, sun-baked earth. (p. 23-4)
