divaricate with fl. and fruit. A very large plant, 3 — 6 ft. high. 
— ^. genuina (Syme) ; pan.-branches shorter " divaricate with 
fl. afterwards ascending." — a. Banks near the sea. ;3. Damp

11. F. praten'sis (Huds.) : pan. close subsecund, branches in 
pairs one hearing a single spikelet the other several never divari- 
cate, spikelets linear-oblong of 5 — 10 rather distant fl., dorsal 
rib of lower pale ending at or just below the tip or forming a 
very short awn, 1. linear-lanceolate. — E. B. 1592. P. 46. /''. 
elatior (L. em., Koch). — A smaller plant than the preceding. 
Rachis triangular. Pan.-branches ascending ; one of each pair 
nearly always reduced to a single spikelet. In this and the 
preceding the pale is blunt or acute according as the midrib is 
or is not attached up to the tip. — /3. F. loliacea (Huds.) ; spikes 
solitary alternate long slender truly distichous, lower ones 
stalked, rarely in pairs, upper nearly sessile, fl. distant, lower 
gl. 5^8-ribbed, veins of lower pale parallel, no awn, rachis 
flattish. On water meadows spikelets ai'e often all sessile and 
upper gl. vanishing, [now usually regarded as a hybrid between F. 
pratemsis and LoZiwm peremHC-] — E. B. 1821. P. 45, 113 & 114. — Wet 
meadows. P. VI. VII. E. S. I.

2. B. ramosus (Huds.) ; pan. drooping with long divaricate 
slightly divided branches, spikelets lanceolate, fl. remote linear-
