GRAMINEiE. 
3. B. sterilis (L.) ; panicle drooping, peduncles long slightly 
branched, spikelets lanceolate, fl. remote linear-lanceolate, outer 
palea glabrous shorter than its awn with 7 distinct equidistant ribs, 
L pubescent.— E. B. 1030. R. 1583. Par. 50.— Height 1—2 feet. 
L. broad, flat. — Waste places. A. VI. 
4. B. madritensis (L.) ; panicle erect scarcely branched, pe- 
duncles short, spikelets lanceolate, fl. linear remote subcylindrical, 
outer palea 7-ribbed twice as long as the smaller glume and about 
as long as its awn. — E. B. 1006. R. 1584. Par. 50. B.diandrus 
Curt. — St. 6 — 12 in. high, glabrous. Rachis and pedicels sca- 
brous. Remarkable for its erect panicle. — /3. rigidus (Bab.) ; 
panicle compact, pedicels very short, upper part of the st., pedi- 
cels, rachis and glumes pubescent. B. rigidus (Roth) R. 
1586. — Dry sandy places, rare. &. Channel Islands. A. VI. 
VII. E. S. 
5. B. maximus (Desf. ?) ; panicle erect lax at length nodding 
slightly branched, peduncles elongated after flowering, spikelets 
lanceolate downy, outer palea 7-ribbed about half as long as its 
awn. E. B. S. 2820.— Height 1—2 feet. A most beautiful 
grass. — Probably it is B. Gussonii (Pari.) and perhaps distinct 
from the original B. maximus which I have not seen. — Sandy 
places. Channel Islands. A. VII. 0. 
42. Serrafalcus Parlatore. 
1. S. secalinus ; panicle loose drooping in fr. slightly com- 
pound, simple peduncles about equalling the oblong glabrous 
spikelets, fl. at first loosely imbricated afterwards distinct about 
as long as the straight awn, outer palea not overlapping the next 
fl., 1. hairy with nearly smooth sheaths. — Bromus E. B. 1171. 
Par. 49. — In fr. the fl. are quite separate and the spikelets pen- 
dulous. Summit of the larger glume half-way between its base 
and the summit of the second fl. on the same side. Outer palea 
not twice as long as broad, longer than the inner. — /3. velutinus 
(Koch) ; panicle nearly simple, fl. larger downy. B. velutinus 
Sm. E. B. 1884. I follow Koch in considering this to be a 
var. of S. secalinus. — Corn-fields. /3. Between Edinburgh and 
Newhaven. Sm. A. VI. VII. 
2. S. commutatus ; panicle loose slightly drooping compound, 
simple peduncles equalling or longer than the oblong-lanceolate 
glabrous spikelets, fl. loosely imbricated about as long as the 
straight awn, L and sheaths hairy. — Bromus Schrad. B.pratensis 
Sm. E. B. 920. B. arvensis Par. 49. — Outer palea only slightly 
overlapping that of the next fl. at the base when in fruit. Summit 
of the larger glume half-way between its base and the summit of the 
second ft . on the same side. Outer palea twice as long as broad, 
longer than the inner.— Common. A. VI. VII.
