keel. Corolla quite smooth. Not indigenous to Scotland. See Mur- 

 ray's Northern Flora. 



4. A. biilbosus, h. (tuberous Fox-fail-grass) ; culm erect, panicle 

 spiked cylindrical acuminate, calyx-glumes acute slightly hairy 

 free, root tuberous. E. Bot. t. 1249. 



Wet salt-marshes in England, but rare : near Yarmouth and We}'- 

 raouth. In CarditF marshes, Wales. Fl. July. %. — The inflorescence, 

 though very dense, is not a true spihe. The pedicels mostly bear shigle 

 flowers, but often another very small abortive one. Calyx-glumes en- 

 tirely distinct to the base. 



5. A. geniculdtus, L. (foating Fox-tail-grass) ; culm ascend- 

 ing bent at the joints, panicle spiked cylindrical obtuse, calyx- 

 glumes united at the base obtuse slightly liairy and fringed, awn 

 twice as long as the corolla. E. Bot. t. 1250. 



In pools and wet and marshy places, sometimes on dry ground. Fl. 

 July, Aug. 1^. 



6. A. fi'ih-iis, Sm. {orange-spiked Fox-tail-grass) I culms ascend- 

 ing bent at the joints, panicle spiked cylindrical obtuse, calyx- 

 glumes united at the base obtuse slightly hairy and fringed, awn 

 the length of the calyx. E. Bot. t. 1467. Hook. Scot. i. p. 22 {tm- 

 der A. genicidutus.) — A. geniculattis, Host, Gram. Austr.v.ii.t. 32. 



Ponds and ditches ; near Birminffham ; Norwich ; Essex ; Wrexham ; 

 and in Angus and Fifeshire, Fl. July. "U.— l had certainly considered 

 this plant, in Fl. Scotica, as not diti'erent from A. geniculutus. Awrt 

 inserted higher up than in A. genie; spihe more slender and paler. Ari- 

 thers orange-coloured. 



15. Phalaris. Linn. Canary-grass. 



1. * P. Canariensis, L. (cultivated Canary-grass); panicle spiked 

 ovate, cal. -glumes boat-shaped entire at the point accompanied 

 by the single valves of 2 other florets. E. Bot. t. 1310. 



Naturalized in many parts of England and Scotland. Fl. July. O . — • 

 1 — 2 feet high, glaucous, ieoues broad. Spihes handsome, composed 

 of large, pale, yellow-green calyx-glumes, marked with deeper lines and 

 singularly keeled at the back. Canary-seed, as we see it, is not only the 

 seed of this plant, but the seed invested closely (as all grass-seeds are) 

 with the pericarp, and that again with the hardened corolla, which occa- 

 sions its glossy appearance and pointed form. 



2. P. arundindcea, L. (Reed Canary- grass); panicle erect its 

 branches patent, florets clustered secund, imperfect floret con- 

 sisting of a small hairy valve. E. Bot. t. 402, and t. 2160,^ 2. 

 — Arundo coloi-ata, Fl. Br. — Digraphis, Trin. Lindl. 



Sides of lakes and rivers, common. Fl. July, Aug. If. .—Frequent in 

 gardens, with variegated leaves and called ribband-grass. Very different 

 from the last in general habit, but not in essential character. Panicle 

 large, 6 — 8 inches long, often brownish or purplish green. Excellent for 

 securing river hanks ; its roots are creeping, and here and there tufted. 



16. Ammophila. Host. Sea-reed. 

 1. A. arundincicea, Host, (common Sea-reed, Mariim, or 3Iat'
