rough, and not easily observable. Stems sometimes branched. 
Not distinct from P. nemoralis. 
31. Poa nemoralis.—Cheshire, June 7, 1827, (hedges and 
woods, but rare.)—I perceive no difference between this and 
P. glauca, as to the shape of the spikelet, and in both the 
outer calyz-glume is 3-ribbed; nor is there any difference in 
the florets, the outer valve in P. nemoralis being blunt as in 
P. glauca. 
32. Festuca uniglumis.— Garden, June 11, 1827, the seeds 
from Anglesea in 1825.—No styles visible. Stigmas much 
branched, but not feathery. Germen bristly at the summit, 
at first turbinate, afterwards much elongated. Stem 4-angled, 
near the top.—By cultivation, this grass becomes very tall, 
(more than 12 inches high,) and perfectly erect: in a wild 
State, its stems are mostly decumbent. ‘The description in 
Eng. Fl. very good. 
33. Arundo Phragmites.—September 16, 1826.—Outer 
glume of calyx brownish-purple, with several ribs: inner 3- 
ribbed, and purple like the florets; lower floret (in a dwarf 
specimen, ) without any pistil, but with a nectary of 3 scales, 
(the additional one smaller and opposite to the inner valve,) 
the other florets have a nectary of two scales, which are large, 
rounded, and a little dilated, sometimes very slightly notched. 
Stamens between the nectary and pistil: hairs of the upper 
florets in two opposite tufts, placed on the be of the com- 
mon stalk, immediately below the floret. 
34. Lolium perenne.—September, 1896. Noctary « of 9 
ovate, acute scales, not cloven or concave, very fleshy below : ; 
outer valve of the corolla 5-ribbed. 
35. Lolium £emulentum.—W ales, June, 1826. — This. and 
L. arvense are but varieties of one species; both are found, 
with intermediate states, in the same field. In L. temulentum, 
however, the stem is smooth as well as the sheath; this cir- 
cumstance and the difference in the shape, size, and direction 
ofits awn, are the only characters visible. | 
.36. Hordeum murinum.—The calyx of the lateral flowers 
very nearly resembles that of the central one. I distinguish
