ation in the atmosphere as to keep them in an apparently spontaneous motion, when they resemble some gro- 
tesque insect crawling on the ground. 
172. Trisetum. (Three bristles) ; on account of the three beards or awns of the flower. Trisetum pubescens, 
according to the Woburn experiments (vii.), possesses several good qualities, which recommend it to parti- 
cular notice. It is hardy, early, and more productive than many others which affect similar soils and situ- 
ations. It appears well calculated for permanent pasture on rich light soils. Trisetum flavescens is also a use- 
ful grass ; but the most valuable as a grass is the Avena elatior, L. the Holcus avenaceus of Eng. Bot., which 
will be noticed hereafter in its proper place. (In Polygamia monoecia, under Arrhenatherum). 
173. Danthonia. A genus containing some incongruous species of Avena, and named after M. Danthoine, a 
French botanist. 
174. Gaudinia. Named in honor of M. Gaudin, a Swiss botanist, who paid great attention to the study of 
grasses, and who published an Agrostographia Helvetica in 1811, still a work of reputation. 
175. Arundo. An ancient name of doubtful origin ; perhaps, as a recent author conjectures, from aru, the 
Celtic word for water. Phragmites is derived from (p^ay/u^s, a hedge or separation. A. donax, Canne, Fr., 
Rohr, Ger,, and Cantii di Giardini, Ital. is common in the south of France and Italy, where it is cultivated as 
fence-wood, for supporting the vine, for fishing-rods, and a great variety of purposes. In Spain and Portugal 
it forms an article of commerce, and supplies materials for the looms, fishing-rods, &c. of this country. The 
striped-leaved variety (gardener's garters) used formerly to be a common inhabitant of gardens. 
A. phragmites, Roseau de Marais, Fr. Gemeine Rohr, Ger. ; and Carina palustre, Ital. is used for thatch- 
ing, for protecting embankments or sea-dykes, for ceilings to cottages, verandahs, and rustic buildings ; to lay 
across the frame of wood work as the foundation for plaister floors, and for screens and hot-bed covers in 
kitchen gardens. The panicles will dye wool green ; and the roots, it is said, are good in liver complaints, like 
those of Triticum repens. 
176. Chrysurus. From x.i»)f0Si gold, and ieoi,, a tail ; the compact heads of flowers are of a bright yellow 
color. 
177. Sesleria. A genus named by Scopoli, after Leonard Sesler, a physician and botanist, who contributed to
