Light dry pastures and sandy ground near the sea, not rare in Eng- 

 land. Rare in Scotland, and principally found in Angusshire. ©. 6. 



AH our British grasses of this genus are admirably characterized 



by the form, &c. of their glumes. The present is the smallest species, 

 procumbent at the base and glaucous. 



37. Triticum Zf?2?z. Wheat, or Wheat-grass. (Tab. VIII. f. 34.) 



Spihelets solitary, transverse, the sides (not the backs) of 



the glumes and florets directed to the rachis, compressed, many- 



Howered. Glumes 2, opposite, nearly equal, both with 3 or 



1-2 more nerves or ribs. Glumellas 2, lanceolate, outer one acumi- 



and nate or awned at the summit, inner bifid at the point, fninutely 



G?w- ciliated on the ribs. Caryopsis free. — There are two natural 



! groups in this genus: 1st, the large annual species foreign to 



our country, which are cultivated so extensively as Bread-corn;

 genera, Triticum and Agropyrum (Beauv. LindL') We have 

 only the latter genus or group in Britain.— Name : Triticum^ 

 " quod t7ifuni est e spicis ;" because it is thrashed or beaten 

 from the spikes. 



1. T. "" cristdtum Schreb. (crested TF.); spike short with 

 closely imbricated 3 — 5-flowered spikelets, glumes subulate 

 with a terminal awn 6-nerved, outer glumellas 5 -nerved with 

 an awn as long as themselves, rachis of the spike and spikelets 

 slightly downy, leaves hairy on their upper surface, culm rough.

almost peculiar to the east of Europe and Asia, rarely occurring (and 

 perhaps only when introduced) in the south of Europe, not, we be- 

 lieve, a native of France, and which could not have been indigenous 

 to the station assigned above. On one side of the midrib (or that

which runs into the awn) of the glumes there are 2, on the other 

 S ribs. It somewhat resembles Hordemn maritimum, but is at once 

 distinguished by the solitary several-flowered spikelets. 



2. T. junceum L. (rushy Sea TF.) ; glaucous spikelets distant 

 4 — 6-flowered, glumes obtuse many-ribbed, outer glumella ob- 

 tuse or slightly mucronulate 5 -nerved, keel and mucro of glumes
