. E, grandis, sp? m. — A tall grass, 3—4 ft. high, the erect terete 
iii about 2’ thick, constricted at the black nodes. Leaves poe 
dark-green, paler on the upper face, flat, 15—20‘ long, 4—6” bro 
gradually drawn out to a long icabrons int, bearded at the mouth "at 
the close vagina, otherwise glabrous. Panicle sisewad at last, spreading, 
pyramidal-oblong, narrowing below, 12—15'‘ * 4—5’, the slender rays 
erect-patent, dividing from near the base, mostly in irregular fascicles 
of 4—5, the longest measuring 3!/2—6‘, Main rhachis smooth, bearded 
in the axils with long soft ciliae; rays roughish near their ends only. 
Spikelets subracemose on pedicels of much less than their own length, 
dark-green, lanceolate-oblong, flat, 2"/:—31/2” long, 10—13-flowered, with 
glabrous axis. Outer glumes very acute from a broad base, 1-nerved, 
denticulate at the keels, slightly unequal, each #/s less in height than its 
next floret. Flowering glumes ovate-lanceolate, acute, 3-nerved, the nerves 
uniting at the apex, denticulate at the keels, as are also the bidentate or 
truncate paleae. npr rns ogi en ciaasil
