TRIAND. DIGYN. 45 



Except the fibrous roots and long awns, it is difficult to point out a 

 mark to distinguish this from the foregoing species. In its fructifi- 

 cation, and that of Tr.caninum and Tr.ji<nceu»i, the varieties are 

 so numerous that it is scarcely possible to draw the line of discri- 

 mination. 



4. Tr. cristaium [crested IV heat- grass), valves of the cal. sub- 

 ulate keeled aristate scarcely nerved of about 4 avvned flowers, 

 spikelets much crowded. E.B. t. 2267. 



Hab. Sea-side between Arbroath and Montrose, G.Don. F/. July. 1/ , 

 Culm 1 foot or more high, pubescent upward. Leaves linear, acu- 

 minated, hairy on the upper surface. Spike dense, oblong, al- 

 most 4-sided. Spikelets very regularly distichous, standing out 

 nearly horizontally, lanceolate. C'«/. valves small, subulate, awned. 

 Outer valve of the cor. lanceolate, longer than its awn. — A rare 

 Grass, very little known even on the continent. 



** Spike secund. 



5. Tr. loUaceiim {spiked Sea Wheat-grass), valves of the cal. 

 indistinctly 3-nerved obtuse of many awnless flowers, root 

 fibrous annual. E. B.t. 22\. 



Hab. Sea-coast, Angus-shire, G. Don. Shore of the Isle of May and 

 Firth of Forth, plentiful, D. Don. \Valls, Caroline Park ; and 

 rocks east of Granton, and west pier of Burntisland, Edinb., Mr. 

 Arnott. Pettycur, Fiteshire, abundant, Mr. Greville. Fl. June, 

 July. ©. 



Singularly stiftand wiry, equally so with Poa rigida. 3 — 4 inches high. 

 Leaves linear, rigid, plane. Spikelets more or less distant, secund, 

 on veiy short footstalks ; lower ones sometimes 2 — 3 together. 

 Ext. valve of the cor. broadly ovate, concave. 



2S. LOLIUM. 



1. L. peremw {perennial Darnel o\' i?ye-gra5i), spikelets much 

 longer than the cat., florets awnless linear-oblong compressed, 

 root perennial. IJgliif. p. 107. E. B.t.^Xo. 



Hab. ^^'ay -sides, pastures and waste places, abundant. Fl. June, 



July. %. 

 One to one foot and a half high. Spike with the habit of Triticum 



rep., sometimes from luxuriance compound. F/ore^s linear-oblong, 



nerved. 



2. L. arvense {annual Darnel), spikelets about as long as the 

 calyx, florets elliptical with very short soft awns, root annual, 

 JE. B. t. 1125. 



Hab. Forfar, and fields Angus-shire, G.Don. Fl. July. ©. 

 Very nearly allied to the following species. 



3. L. temulentum [bearded Darnel), spikelets shorter than 

 the cal., florets elliptical about as long as the rigid awn, root 

 annual. Light/, p. \07. E. B.t. l\2L
