leaves variegated with white lines (Parn. Gr. t. 82) is frequent in 
gardens, and called ribbon-grass, striped-grass, or gardener s garters. 
Very different from the last in general habit, but not in essential 
cnaracter. Panicle large, 4 — 8 inches long, often brownish or 
purplish- green. Useful for securing river banks ; it has a creeping 
rhizome, and is here and there tufted. 
6. Piileum Linn. Cat’s-tail-grass. (Tab. VI. f. 6.) 
Panicle spike-like. Spikelets laterally compressed. Glumes 2, 
nearly equal, parallel, acuminate or mucronate-aristate, longer 
than the floret. Glumellas 2, membranous, glabrous, awnless. 
Styles elongated. Caryopsis free. — Named from cpXtog, or 
i phone , formerly applied, it is supposed, to the reed-mace 
( Typha ), to which our grass bears some distant resemblance. 
* Glumes truncate and scarious below the apex . 
1. P. pratense L. ( common C., or Timothy-grass) ; panicle 
cylindrical, glumes truncate mucronate-aristate ciliate at the 
back at least twice as long as the awn, neuter floret wanting. 
E. B. t. 1076 : Parn. Gr. t,t. 6, 77, 78. 
Meadows and pastures, very common. If . 6 — 1 0. — Rhizome 
sometimes tuberous, and then the plant is the P. nodosum Linn. 
Glumes, as in all the species, extremely compressed, keeled with a 
dorsal green nerve running out into a spreading awn, scarcely half as 
long as the glume. 
2. P. alpinum L. ( alpine C .) ; panicle oblong or ovate- 
oblong, glumes truncate mucronate-aristate ciliate at the back 
scarcely as long as the awn, neuter floret wanting. [ — a. awn 
ciliate, upper sheath scarcely inflated and about twice the 
length of the leaf, uppermost ligule oblong acute.] — /3. awn 
scabrous, upper sheath inflated 3 — 4 times the length of the 
leaf, uppermost ligule very short obtuse. E. B. t. 519 : Parn. 
Gr. t. 6. P. commutatum Gaud. 
13. Banks of mountain-streams, rare. Breadalbane mountains ; 
Feula burn, Canlochen Glen, Glashie burn, White Water above Glen 
Dole, Glen Fiadh, and rocks near Loch Brandy, Clova ; Loch-na-gar 
and Braeriach, Aberdeenshire; Garvie moor, Invernesshire. If.. 7. 
— Spihe purplish, variable in length, sometimes only half an inch, 
sometimes lg inch long. The awns in our Scottish plant “are gene- 
rally scabrous ; but in some instances the scabrous processes towards 
the base are so elongated as to become cilias:” Gardn. The car. a. 
has not yet occurred in this country. 
** Glumes acuminate or contracted into a short point but not truncate. 
3. P. usperum Jacq. (rough C.) ; annual, panicle cylindrical, 
glumes wedge-shaped tumid upwards mucronate rough, neuter
