Ischaemum rugosum (Actually there are two racemes adpressed to each other like a lock and key and appear as a single raceme. They usually sometimes split apart partially or fully on maturity. You can forcefully open up the two racemes). Rugosum means wrinkled. You can see the wrinkles on the lower glume of the spikelets
