\Panicum. 
In a narrow mountain valley, called Kella (Cally?) in Angusshire: 
G. Don. Near Thurso, Caithness: Mr. Robert Dick (1854). I/.. 
5. — About 1 foot high, glabrous. Leaves linear-acuminate. Panicle 
brownish, glossy. Spihelets broadly ovate. Glumes ovate, acute, 
rather unequal, sometimes a little serrate at the point. Florets rather 
longer than the glumes ; the outer glumellas are of a firmer texture, 
scabrous when highly magnified, distinctly fringed at the margin, the 
point sharp, but not awned. Central floret the smallest. Smell re- 
sembling that of Anthoxanthum odoratum. Don’s station has not been 
verified; but the plant is abundant near Thurso. 
24. Paniccm Linn. Panic-grass. (Tab. VII. f. 21.) 
Spikelets flat in front, convex on the back, 2-flowered, with- 
out bristles at the base, usually on one side of the partial rachis, 
and arranged in a compound spike, raceme, or panicle. Glumes 
2 ; lower one (in front) small, upper as long as the spikelet. 
Lower (or anterior) floret as long as the upper, barren and 
triandrous or neuter: glumellas 1 — 2; outer with the texture of 
and as long as the upper glume. Upper floret perfect ; glumellas 
2, cartilaginous, enveloping the caryopsis, neither awned nor 
setigerous, very rarely mucronulate. — Named from panis , bread; 
the seeds of some species being used for bread. — The British 
species belongs to that section called by Beauvois Echinochloa , 
and distinguished by the spikelets in a compound raceme , the 
upper glume and lower glumella of the sterile floret with a long 
awn-like bristle. 
1. P. (Ech.) *Crus-galli L. (loose P.) ; “culms erect tufted 
at the base, leaves linear acuminate more or less scabrous on 
the upper side, sheaths glabrous, ligule none, spike compound 
erect, partial ones alternate unilateral somewhat close-pressed 
to the compressed triquetrous common rachis, spikelets ovate 
turgid hispid (greenish), lower glume broadly cordate-ovate 
with an embracing base mucronate thrice shorter than the 
spikelet, upper ovate acuminate 5-nerved, neuter floret with 
2 glumellas the lower with a longish bristle, caryopsis even 
gibbous ovate with a hispid point.” E. B. t. 876. Echinochloa

7. — The whole group called Echinochloa is in so great confusion, 
that we scarcely know what the naturalized British species really is, or 
whether there are not several. The above character of the true P. 
Crus-galli by Nees v. Esenbeck is derived from foreign specimens. 
25. Setaria Beauv. Bristle-grass. (Tab. VII. f. 22.) 
Panicle compound, somewhat cylindrical, spike-like. Spihe- 
lets flat in front, convex on the back, 2-flowered, 1 — 3 together,
