Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 8-15; digitate; erect, or ascending; unilateral; 9-11 cm long. Rhachis subterete. Spikelet packing broadside to rhachis; regular. Spikelets appressed; solitary. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
