This main photo is pure Oplismenus hirtellus as it has the awns. It was the taller grass that went to the top of the photo and had long right-angled leaves in the second photo that was Entolasia marginata. But there is also Oplismenus hirtellus in that photo as well. The long weeping flowerheads in the third photo are also E marginata, but the shorter wavy leaves are O hirtellus
