groups in this genus: 1st, the large annual species foreign to 
our country, which are cultivated so extensively as bread-corn; 
and, 2ndly, the smaller perennial species, many of which are 
natives with us. These some authors look upon as 2 distinct 
genera, Triticum and Agropyrum ; we have only the latter genus 
or group in Britain. — Name: Triticum , “quod tritum est e 
spicis ; ” because it is thrashed or beaten from the spikes. 
[1. T. *cristatum Schreb. ( crested IF.) ; spike short with 
closely imbricate 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.

“ On steep banks and rocks by the sea-side between Arbroath and 
Montrose:” G. Don, who alone has found it. It- 7. — A plant al- 
most 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 cotild 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 
3 ribs. It somewhat resembles Hordenm maritimum, but is at once 
distinguished by the solitary several-flowered spikelets.] 
2. T. junceum L. (rushy Sea IF.) ; glaucous, spikelets distant 
4 — 6-flowered, glumes obtuse or apiculate many-ribbed, outer 
glumella obtuse or slightly mucronulate 5-nerved, rachis of the 
spike glabrous brittle at the nodes in fruit, leaves involute pun- 
gent downy above with numerous soft very short spreading 
hairs on each rib, rhizome creeping. E. B. t. 814: Pam. Gr. 
t. 63. 
Sandy sea-shores, frequent. 1/.. 7, 8. — Whole plant glaucous, 
rigid, lit — 3 feet high. Spike long. Spikelets oblong, much com- 
pressed, their rachis glabrous or slightly downy, especially on the 
angles. Glumes oblong-lanceolate, often 3-toothed at the summit, 
oblique, 6 — 10- (usually 6-) ribbed ; the midrib, which is the longest, 
and sometimes forms a small apiculus, is not in the centre, but has 
more ribs or nerves on one side than on the other ; besides these 
principal ribs, there are usually intermediate smaller ones at the base, 
which disappear about the middle. Outer glumellas similar to the 
glumes, but equal-sided, all or the upper ones with a blunt mucro 
formed by the excurrent midrib. 
3. T. laxum F ries ( fiat-leaved Sea IF.) ; glaucous, spikelets 
often approximate 5 — 8-flowered, glumes obtuse or mucronate 
about 7-ribbed, outer glumella obtuse apiculate 5-nerved, rachis 
of the spike smooth or minutely toothed on the angles tenacious, 
of the spikelets downy, leaves usually flat scabrous above with 
many acute points on each rib involute when dry, rhizome more 
or less creeping. T. junceum j3. Br. FI. ed. 6.
