CLASSIFICATION ACCORDING TO [CH ° 
No other genus of our grasses is like Hordewm. The purely 
superficial resemblances in the inflorescences of Polypogon, Lagurus, 
and Cynosurus echinatus—all extremely rare species—disappear at 
once on examination. 
In Bromus erectus the equally superficial resemblance is due to 
the stiff awns: the spikelet has six to twelve flowers and is stalked. 
It should also be noted that Hordeum sylvaticum occasionally 
has a rudimentary second flower in the lateral spikelets (see note 
p. 105). 
(a) A shade-grass with the central spikelet only 
imperfect ; staminate, or rudimentary, or en- 
tirely wanting. 
HH. sylvaticum, Huds. 
(8) The central spikelet is the perfect one, the 
two lateral barren. Growing in open land. 
(Gi) A perennial meadow-grass. All the 
glumes scabrid and bristle-like. 
H. pratense, Huds. 
(ii) Annuals with some of the glumes at 
least, lanceolate or broad below. 
*  Ruderal plant, with cylindrical spikes, long 
awns; glumes of the central flower dilated 
below. 
H. murinum, With. 
** Maritime plant, more or less glaucous, with 
short ovoid spikes: glumes of the central flower 
bristle-like. 
H. maritimum, With. 
(b) Spike cylindrical, of sessile or nearly sessile 
awned spikelets, densely crowded round the 
axis, the whole resembling a fox’s brush or 
cat’s tail.
