This is a tufty grass with very long leaves, including leaves that also branch out from the flowering stem (photos 2 & 3 show this, clearest in #2, but better sense of scale in #3). It has grey-green leaves, and the base of the stems, and some parts of the stems themselves have some dark red colouring (refer photo 1, also photo 3 - LH stem 1/3 up from the bottom). (This may be the same Species as the grass at sighting 4651573 which also has segments of stem coloured red, then green in an alternating pattern, amongst other similarities).
