Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary with a villous apical appendage or simply hairy; styles inserted at the appendage, short; stigmas plumose, laterally exserted.

Caryopsis oblong to linear in outline, convex-concave, with an apical ciliate appendage, usually tightly enclosed by the palea; hilum filiform, very long.
Morphology Reproductive morphology Inflorescences
Inflorescence a simple terminal raceme (pseudo-spike), with the spikelets alternating in 2 rows on opposite sides of the rhachis. Rhachilla disarticulating above the glumes and between the florets, glabrous, smooth.
