RIVERSIDES, PONDS AND MARSHES 3t 
one foot or more. Panicle pyramidal and diffuse, with very evident 
half-whorls of unequal branches, 3-5 at each insertion. Spikelets 
about 4 inch long, obconic, yellowish purple, usually 2-, sometimes 
3-flowered. All the glumes have erose tips (¢.e. truncate and with 
shallow notches—a perfectly distinctive character), and are awnless ; 
empty glumes unequal, and not more than half the length of the 
‘eo ones, the latter 3-nerved. Perennial, flowering June, 
uly. 
Calamagrostis lanceolata, the Purple-flowered Small-reed, pre- 
fers the shade of woods and hedges, though sometimes occurring 
in open situations, but always on moist or swampy ground ; it is 
confined to England, and local. Rootstock creeping with long 
stolons. Leaves linear, with numerous unequal slender ribs, flaccid. 
Culms 2-4 ft., slender. Panicle rather lax, spreading at time of 
flowering, tinged with rose-purple, shining. Spikelets nearly 7 
inch long, numerous, I-flowered ; empty glumes very narrow and 
much longer than the flowering one, awnless; flowering glume 
enveloped by silky hairs which slightly exceed its tip, and with an 
extremely minute awn springing from the apical notch. Perennial, 
flowering in July. 
Alopecurus fulvus, the Orange-anthered Foxtail, is closely allied 
to A. geniculatus and occurs in the same habitats, but is restricted 
‘to the southern half of England. Comparing the two species, the 
distinctive characters of A. fu/vus are: leaves pale green with 
slightly rough ribs ; empty glumes a little shorter than the flower- 
ing one ; awn arising from the middle of the flowering glume and 
extending very little beyond the tip. The anthers are shortly 
oblong (not narrow), and bright orange scarlet, which enables one 
to recognise the species at a glance when it is in flower. Perennial, 
flowering June to autumn. 
Leersia oryzoides, the European Cut-grass, as a British plant is 
only recorded from a few localities in S.E, England; it grows by 
the sides of streams and in marshes ; abundant by the Boldre 
River, Hants; Surrey, Sussex. Rootstock extensively creeping. 
Leaves flat, broadly linear-lanceolate with excessively scabrid 
margins, pale green. Culms 2~3 ft. Panicle lax with capillary 
branches, partly concealed in the inflated sheath of the uppermost 
leaf. Spikelets nearly 4 inch long, half oval, pale green and trans- 
lucent, I-flowered ; no empty glumes; flowering glume 3-nerved, 
keeled, awnless, the nerves ciliated with stiff hairs ; palea with 
only one nerve or keel, also ciliate. Flowers of the exserted 
portion of the panicle mostly abortive. Perennial, flowering in 
autumn. 
Deyeuxia neglecta, the Narrow Small-reed, is extremely rare ; 
found in bogs at Oakmere, Cheshire ; on the shores of Lough 
‘Neagh, Ireland, and in Caithness. Very closely allied to Calama- 
grostis lanceolata. Rootstock shortly creeping ; leaves extremely 
narrow with few ribs, flaccid ; uppermost ligule blunt. Culms 2-3 ft. 
Panicle very narrow and lax. Spikelets 4 inch long, containing 
one flower and a rudiment in the form ofa pedicel tipped with a
