floret subulate, stem often branched. Pam. Gr. t. 79- P. 
paniculatum Huds. : E. B. t. 1077. 
Rare in dry open fields, in the western and midland parts of Eng- 
land. 0. 7. — Culms very leafy; the long spikes are partly con- 
cealed among them. 
4. P. Boehmeri Wibel {purple- stalked C .) ; perennial, panicle 
cylindrical, glumes linear-lanceolate suddenly acuminate-aristate 
hispidly ciliateon the keel above the middle, neuter floret subu- 
late. Parn. Gr. t. 80. Phalaris phleoides L. : E. B. t. 459. 
Dry sandy and chalky fields, rare ; principally in Norfolk and 
Cambridgeshire. 2/.. 7. — Culms simple, erect, sparingly leafy, 
slender, shining purple. 
[5. P. * Michelii All. ( Micheli's C .) ; perennial, panicle 
nearly cylindrical, glumes lanceolate acuminate strongly ciliate 
at the back the whole length. E. B. t. 2265 : Parn. Gr. t. 7. 
Rocky parts of the high mountains of Clova, Scotland : C. Don. 
U. 7,8. — Distinguishable at once from the preceding species by 
its gradually tapering glumes, and from the next by the perennial root. 
No one has succeeded in verifying Don’s discovery ; all the specimens 
communicated by him were from his garden at Forfar.] 
6. P. arendrium L. ( Sea C .) ; annual, panicle obovato- 
cylindrical, glumes lanceolate acute ciliate at the back above 
the middle. Parn. Gr. t. 7. Phalaris Huds.: E. B. t. 222. 
On loose sand, especially near the sea. ©. 5, 6. — Culms 5 — 6 
inches high, many from the same root. Glumellas half as long as the 
glumes, membranous, truncate. 
Iff Glumes 2. Styles very short. Stigmas elongated , hairy 
or plumose. 
7. Lagtjrus Linn. Hare’s-tail-grass. (Tab. VI. f. 7.) 
Panicle spike-like. Spikelets laterally compressed. Glumes 2, 
lengthened into a long subulate point, fringed to the end, 
longer than the floret. Glumellas 2, membranous ; outer one 
bifid, ending in 2 long bristles, with a dorsal twisted jointed 
awn. Stigmas slender, slightly hairy. — Named from Kayuioc, 
a hare, and ovpa, a tail. 
1. L. ovdtus L. (ovate H.) : E. B. t. 1334: Parn. Gr. t. 88. 
Very rare. Sandy grounds in the north and west of Guernsey. 
©. 6. — The only species of the genus. Remarkable for its soft and 
pale heads of flowers, from among which the long awns are protruded. 
8. Psamma Beauv. Sea-reed. (Tab. VI. f. 5.) 
Panicle spike-like. Spikelets laterally compressed. Glumes 2, 
nearly equal, keeled, membranous, diverging, longer than the
