GRASS TRIBE 65 
oblong; empty glumes fringed at the back, cut off suddenly at the end, 
shortly bristled, sheath of the upper leaf very long and swollen. This rare 
_ grass is found on the banks of alpine streams at altitudes between 2,100 and 
3,600 feet in Perth, Forfar, and Aberdeen. It has a very short bristly panicle, 
rarely exceeding an inch in length, of a purplish-brown colour, and a creeping 
knotted perennial rootstock. It varies in the degree in which its leaf-sheath 
is inflated, as well as in the roughness of its awn. 
3. Rough Cat’s-tail (P. dsperum).—Panicle cylindrical ; empty glumes 
wedge-shaped, swelling upwards, rough. Annual. This is a rare grass of 
dry open fields in some parts of England. Its stem is about a foot high, often 
branched, and in July its leaves are so long and numerous that they almost 
cover the flower. The panicle is about two inches long. It has been found 
occasionally in fields about Bristol, and in other parts of Gloucestershire, but 
not apparently in recent years. 
4, Purple-stalked Cat’s-tail (P. behméri).—Panicle cylindrical ; empty 
glumes narrow, pointed, spine-tipped, and downy at the keel. Perennial. 
This rare grass grows chiefly on dry sandy or chalky fields in Bedfordshire, 
Norfolk, Cambridgeshire, Essex, and Hertfordshire. It has a glossy purple 
unbranched stem, erect, and about a foot high, and but few leaves. It 
flowers in July. The glumes are leathery, green, with a white margin. It 
is also known as P. phalaroides. 
5. Michel’s Cat’s-tail (P. michélii).—Panicle hairy, cylindrical ; empty 
glumes tapering to a point, with a fringed keel. Perennial. This is not an 
indigenous grass. It was stated to be found on the rocky parts of the Clova 
mountains by G. Don, but, as it is not found there now, some mistake is 
supposed to have occurred. 
6. Sea-side Cat’s-tail (P. arendrium).—Panicle oblong, enlarged at the 
top; empty glumes tapering toa point, fringed on the keel. Perennial. This 
is one of our sand-grasses, of which we have no fewer than seventeen, all 
more or less useful in binding the sands. It grows more frequently on the 
eastern sea-shores of Scotland than England, and though its stem varies in 
height it is most frequently about half a foot, several stems rising from one 
root. Its short, crowded, oblong panicle is of yellowish-green, often tinged 
with a little pinkish colour. It will grow only on loose sands, and is there a 
straw-coloured, bright glossy grass in June and July, and, like our sand- 
grasses in general, of no use to the agriculturist. 
8. (20) HARE’S-TAIL-GRASS (Lagirus). 
Ovate Hare’s-tail-grass (L. ovdtus).—Spikes egg-shaped, with long 
awns projecting from among the down. Annual. This is a rare grass, 
inhabiting sandy places in Guernsey, but naturalized near Saffron Walden, 
and occasionally planted in tufts in English gardens. It is from four to twelve 
inches high, with broad leaves and a soft downy head, over an inch long, of 
pale grayish colour, slightly tinged with pink. 
9. (11) MiLuet-erass (Miélium). 
Spreading Millet-grass (J/. effisum).—Branches of the panicle long, 
and in distant tufts, placed alternately on the stem. Perennial. This is a
