shorter than the glume, keels minutely scabridulous above the 
middle ; grain reddish, ellipsoidal. 
Culm nearly 5 ft. high; basal sheaths to 3 in. long, the upper 
32 to 9 in.; leaves 6 to 12 in. long, greatest width scarcely 
12 line. Root-fibres a good line in diameter. Panicle 11 to 13 in. 
long, by 3 to 4 in. greatest diameter, lowest node hairy, branches 
52 in. long or less, branchlets } in. or less; spikelets generally 
21 to 3 lines long; lower barren gl. } to $ line, upper nearly 1 line 
long ; flowering glumes 1 line; anthers 2 line; grain } line. 
Near the last species (Z. huillensis) which it closely resembles 
in stem- and leaf-characters, but is distinguished by its more 
delicate Aira-like panicle, with whorled branches, less robust 
spikelets, and subequal barren glumes.
