Although looking very like a distinct species, I think it will 

 turn out a variety of G macrocepTiala, notwithstanding its fierce, 

 ovate-lanceolate, acuminate bracts, and perigynia scarcely alate 

 below. No stamens were found. They had probably been long 

 fallen from the terminal glumes of the short spikelets.
