This grass plant is very similar to the grass reported at sighting 4651511, which it is also growing nearby. However the difference I noticed is the shape and size of the seed heads . This plant has slender slim seed heads and the individual seed is more distinct that at sighting 4651511. The latter plant’s seed heads are chunkier and the seeds held together more tightly. Some of the latter's seedhead stems also alternate between green and brown-red, changing to the other colour at the next node.
