Unsure if grass or something else
Lanky growth from the recent rains (1.5m - 2m high), and profusely flowering. Growing in the forest on the Eastern side of Dandenong Creek, on the South-west slopes.
A population in the roadside vegetation of 400+ plants
Very slender leaves, growing in a swampy area. I thought it was austral Brooklime but leaves seem much too narrow
Patches of Poa tenera growing around Gahnia tussocks and along a bank. Stoloniferous habit.
Masses of white seed heads instead of the masses of Yellow flowers a few weeks ago.
