This one a bit weird. Ligules membranous but rather long for this taxa. Initially thought I had come across the seldom seen D. aculeatum but spikelets not sufficiently pointy I'd say

Not positive on ID of R. ciliosa rather than R. caroliniensis however I believe it is due to hairy leaves and flowers and form of plant
