A Shape of body of upper glume: elliptical (0), ovate (1), spatulate (2) [007]24. Texture of the margins of the upper glume: same as body (margin usually appearing as inrolled) (0), tapering (1) [084]25. Submargin of upper glume with distinctive trichomes: absent (0), long cilia (1) tuberculate-based bristles (2) [111]26. Upper glume with 2-keeled margins: absent (0), present (1) [123]27. Upper glume prominently ribbed on the back: no (0), yes (1) [135]28. Upper glume with a small proximal elaiosome: no (0), yes (1) [134]29.

Relative similarity (shape, size, texture, indumentum, chlorophyllous) of upper glume and lower lemma: similar (0), dissimilar (1) [116]31. Similarity of the indumentum (type and distribution) on the upper glume to that on the lower lemma: similar or absent (0), dissimilar (1), very dissimilar (2) [014]32. Shape of apex of lower lemma: truncate (0), obtuse (1), broadly acute (2), narrowly acute (3) [003]33. A Shape of body of lower lemma: elliptical (0), ovate (1), spatulate (2) [088]34. Texture of margin of lower lemma: normal (same as body) (0), tapering (1), hyaline at least proximally (2) [020]35.
