of each of the lower pairs of branches is divaricated after flower- 
ing.—Banks. P. VI. VII. 
8. F. pratensis (Huds.); panicle close, branches in pairs one 
bearing @ single spikelet the other several never divaricated, 
spikelets of 5—10 f1., dorsal rib of outer pale terminating at or 
Just below the apex or forming a very short awn, 1. linear-lanceo- 
late.—E. B. 1592. P. 46. F. elatior Koch.—A smaller plant 
than the preceding. Branches of the panicle ascending, not diva- 
nicated after flowering; one of each pair nearly always reduced 
to a single spikelet. Spikelets leaning to one side. In this 
and the preceding the outer pale is obtuse or acute according 
as the midrib is or is not attached up to the summit.—. F. 
loliacea (Huds.); spikelets solitary alternate, truly distichons, 
lower ones stalked, upper sessile. This var. is distinguished from 
Glyceria fluitans, to which it bears much resemblance, by its 
very short ligule, 3-ribbed upper glume and 5-ribbed outer pale. 
FE. B. 1821. P. 45,113 and 114. Mr. Borrer considers these 
pee ie distinct. They deserve careful study.—Wet meadows. 
42. Bromus Linn.' 
* Spikelets broader upwards when in flower. 
1. B. erectus (Huds.); panicle erect, spikelets lanceolate, fl. 
remote subcylindrical, outer pale indistinctly 7-nerved 4 longer 
than the smaller glume and longer than its awn, root-l. very 
narrow ciliated.—H#. B. 471. P. 51.—St. 2—3 feet high, erect. 
Upper |. broader than the others, sheaths somewhat hairy, the 
hairs pointing upwards.—8. villosus; outer pale hairy.—On dry 
sandy and chalky soil. P. VI. VII. 
2. B. asper (L.); panicle drooping with long slightly divided 
branches, spikelets lanceolate, fl. remote linear-lanceolate, outer 
pale hairy 5—7-ribbed twice as long as the smaller glume and 
longer than its awn, l. broad bairy—E. B.1172. P. 51.—St. 
4—5 feet high. LL. broad, flat, the lower ones broadest, sheaths 
with hairs pointing downwards.—Damp woods and thickets. A. 
or B. VII. 
** Spikelets always broader upwards. 
3. B. sterilis (L.); panicle drooping, with long slightly divided 
branches, fl. remote lnear-lanceolate, outer pale glabrous shorter 
than its awn with 7 distinct equidistant ribs, |..pubescent.—E. B. 
1030. P. 50.—Height 1—2 feet. L. broad, flat.— Waste places. 
A. VI. 
4. B. diandrus (Curt.) ; panicle erect, branches scarcely divided 
short, spikelets lanceolate, fl. linear remote subcylindrical, outer 
pale 7-ribbed about as long as its awn, 2 lateral ribs close together 
1 Synonymous with the genus Schedonorus of Fries.
