Order XCVIII. GRAMINEiE. 
Fl. perfect or unisexual, 1, 2 or more seated bifariously on a 
common axis which is contained within an involucre of 2 (or 1) 
valves (glumes) or rarely none, the whole forming a locusta oi 
spikelet. Each fl. of 1 or 2 scales (pales) of which the outer 
or lower is simple and usually keeled, the inner with 2 veins 
or keels. Hypogynous scales 2, 3 or none. Stam. hypogynous, 
1 — 6, usually 3. Anth. versatile, notched at both ends. Ovary 
1 -celled. Styles usually 2, rarely 1 or 3. Embryo on the out- 
side of the albumen and at its base. — L. with split sheaths.' 
Flowers closed. Styles or stigmas long, protruded at or near 
to the top of the flower. 
A. Rachis of in/torescence tvithout lateral excavations. 
Tribel. PANICE^E. Spikeletsdorsa/iy compressed, \-floicered, 
or with 1 fl. and an inferior glumelike rudiment or a neuter 
flower. Lower gl. much the smaller, often rudimentary. 
1. DiGiTARlA. Spikes fingered. Spikelets in pairs on one 
side of the flattened rachis, awnless, 1-tlowered, with an 
inferior rudiment. Gl. 2, lower smaller or 0, upper 3- 
veined. Sterile fl. of one 5 — 7-veined pale equalling the

[Since the last edition appeared a large number of so-called varieties of 
Grasses have been published as British ; many of these we have ignored, being 
apparently merely trivial and transitory variations characterized by slight difl'er- 
ences in stature, habit, or colour, more condensed or extended inflorescence, 
broader or narrower leaves, greater or less hairiness, and the like.— H. & J. G.] 
- The suborders of Fries although convenient for us will not apply generally , 
see Bentham, Linn. Soc. Journ. xix. 26. Bentham says practically useless except 
for grasses in a living state. They are retained here as we use them in that 
state of the plants.
