Notes
I have not seen the GRABOWSKY collection from Borneo on which BOECKELER founded his C. grabowskianus, “species insignis in viciniam C. scabridis et C. ehrenberghiani”. I doubt whether KÜKENTHAL’S reduction to C. compactus is right as the young plant was described as having cylindrical-ovoid, small spikes and 2-flowered spikelets.
