shoots. — Mitten in Lond. Journ. Bot. vii. p. 531: E. B. S. 
t. 2955. 
On cultivated land, amongst various crops, about Ilurstpierpoint, 
Sussex; field near Catterick Bridge, Yorkshire. ©. 7. — With 
this we are scarcely acquainted, and authentic specimens appear to 
have been equally unknown to Kunth. It seems only to differ front 
the next by the glumes being considerably shorter than the spikelets.] 
4. L. temulentum L. ( Darnel ) ; spikelets about 6-flowered 
equal to or shorter than the glume, florets awned or awnless 
elliptical in fruit tumid, root annual without barren shoots. — 
a. florets with rigid awns about as long as or longer than the 
glumella. E. B. t. 1124: Barn. Gr. tt. 64, ”142. — /3. florets 
with soft imperfect awns or awnless. L. arvense With.: E. B. 
t. 1125. 
Corn-fields. Not common in Scotland. 0. 6 — 8. This is best 
distinguished from L. perenne by the truly annual root (without 
barren shoots), and the tumid florets. 
|| Bachis alternately excavated between the joints. 
40. Lepturus B. Brown. Hard-grass. (Tab. VIII. f. 37. ) l 
Spike terete, solitary, separating at the joints. Spikelets soli- 
tary in each joint, imbedded in cavities alternately on opposite 
sides of the rachis and placed edgewise to it, with 1 (or 2) fer- 
tile florets and a superior minute rudimentary (sometimes ob- 
solete) neuter one. Glumes (1 or) 2, collateral, on the oppo- 
site side from the rachis and covering the floret, cartilaginous, 
several-nerved. Glumellas of the fertile floret 2, scarious, awn- 
less. — Name from Xsirro?, slender , and ovpa , a tail; in allusion to 
the slender spikes. 
1. L. incurvatns Trin. (Sea Hi ) ; annual, spike subulate, 
glumes 2, without a membranous keel. — a. spike curved. 
Rottboellia L. : E. B. t. 760 : Pam. Gr. t. 2. — f3. spike filiform 
nearly or quite erect. L. filiformis Trin. Rottboellia Both. R. 
incurvata var. filiformis Hook. : Pam. Gr. t. 3. 
Sea-shores, but not common. Frequent on the Irish coast. /3. 
many places along the coast of England. Rare in Scotland, as 
near Aberlady. 0. 7. — Culms 2 — 8 inches high, more or less 
curved, especially the spike. 
1 Although for aiding the student we describe the spikelets as solitary with 2 
glumes, this is not the case, the spikelets being actually, in pairs in Lepturus 
(Diplerma) incurvatus and filiformis ; the fertile one is sessile, having a single 
glume; the other which is pedicellate, is reduced to the mere pedicel resembling 
the glume of the sessile spikelet, and is usually described as a second glume be- 
longing to it. In the true species of Lepturus „ there is only one spikelet at each 
joint, and it is sessile and with one glume.
