CVII. GRAMINE^* 



IBromus. 



1}.. 7, 8. 



A sea-side 



outer glumella 5-nerved rather shorter than Its infraterminal 

 awn, leaves linear-lanceolate ribbed. — a/ panicle larger and 

 more drooping, spikelets about 5 -flowered. E. B. t. 1820. 

 Bromus L. Bucetum Parn. Gr. t. 47.-/3. panicle smaller and 

 more erect, spikelets fewer about S-flowered, leaves narrower 

 r. triflora Srn.: E. B. t. 1918. 



Shady woods and moist hedges, — j3. in Norfolk, and near Forfar 

 in Scotland, probably not unfrequent. 

 grass, 3 — 4 feet high, with broad leaves, having the habit and some of 

 the characters of Bromus, but usually arranged by authors with Fes- 

 tuca. Ligule of the uppermost sheath very shoit. Paw zc/e large. Spike^ 

 lets with 3 — 6 florets. Glumes very unequal, larger ones with 3 ribs. 

 Outer c/lumella lanceolate, obscurely ribbed, nearly glabrous, membra- 

 naceous at the edge upward ; the dorsal rib nearly smooth, not ex- 

 tending to the apex, but terminating in the aw7i, which is thus inserted 

 a little below the bifid point, and is twice as long as the glumella : 

 inner glumella scabrous or very minutely ciliated on the nerves, St^/ks 

 certainly terminal.

32. Bromus Li7m. Brorae-grass. (Tab, VIIL f. 29.) 



Panicle lax or coarctate. Spikelets many-flowered, more or 

 less laterally compressed. Glumes 2. unequal, usually keeled, 

 equal to or shorter than the lowermost florets. Glumellas 2, 

 herbaceous ; outer one rounded on the back, two of the lateral 

 nerves usually uniting with the middle one and forming an awn 

 below the bifid extremity ; inner one conspicuously ciliated on 

 the ribs. Styles from below the summit of the caryopsis^ which 

 is villous at the apex and " adheres to the upi^ev glumellas.'' — 

 ISTamed from f3poij.oc^ given by the Greeks to a kind of oat^ and 

 that again from /3^o/xa, food. 



* Lower glume with one, upper with 3 — 5 nerves. Florets lanceolate. 



1. B. erectus Huds. (upright B.) ; panicle simple erect, spike- 

 lets linear-lanceolate, florets subcylindrical remote about twice 

 as long as the straight awn diverging in flower afterwards erect, 

 outer glumella obscurely 7-nerved, that of the lowermost floret 

 one-third longer than the smaller glume, sheaths somewhat hairy 

 the hairs pointing upwards, root-leaves very narrow cilated. 

 a, spikelets glabrous. E. B. t. 471 : Parn. Gr. t. 51.-/3. culms 

 and spiklets hairy. 



In fields and by road-sides, especially in a sandy soil over chalk. 

 In the King's Park, Edinburgh. 2jL. 6, 7.— Culms, 2—3 feet high. 

 This is truly perennial, which docs not appear to be the case with 

 any other Bromus. Its habit is that of Brachj/podium sylvailcum. The 

 root-leaves are narrow : vpper leaf much broader. 



Awn shorter than the larger glume. 



Spikelets erect. 



2. B. dsperL. (hairy Wood B.); panicle slightly branched 

 droopmg, spikelets linear-lanceolate, florets remote subcylindri-
