phila arenaria, for preserving a considerable extent of our own coasts 

 and those of Holland from the encroachments of the sea. Culms S — 4 



Leaves glaucous, involute, pungent. Spike 4 — 6 



Glumes 2, lan- 



ft. high, glabrous. 



in. long, Spikekts of about 3 flowers on the rachis. 



ceolate, acuminate, downy. Outer glumella resembling them, but 



broader; inner bifid at the point, ciliated on the nerves or angles. 



2. E. geniculdtus Curt, (pendulous Sea Z.) ; spike lax bent 

 downwards, rachis winged, glumes subulate glabrous longer tTiau 

 the florets. E.B. t. 1586: Parn. Gr. t. 131. 



Near Gravesend, in a salt marsh : very rare, ^. 7. — A most 

 remarkable plant, apparently quite distinct from the preceding ; yet 

 we cannot but wish some one wouldstudy it in its locality, Gravesend^ 

 which is the only station recorded for it in this country : it is said to 

 have been likewise found in Holland. We possess something very 

 like it in a disused state of E. arenarius, gathered in Scotland by Mr, 

 M'Nab.

Spikelets in threes from the same joint of the rachis^ 1 — 2 

 usually neuter or barren : fertile ones with a perfect floret and 

 a rudimentary neuter one. Glumes 2, collateral, awned. Glu- 

 mellas 2, — Name of dubious origin. 



Lateral spikelets perfect, middle ones usually neuter (or imperfect ?). 



1. H. sylvdticum HudiS. (Lyme-grass or WoodB.)'^ all the

Woods and thickets, especially in a chalky soil, apparently not 

 rare in the midland and northern parts of England, but not found in 

 Scotland, 1/.. 7, 8. — In former editions of this work reasons were 

 given for uniting this to Hordeumy rather than to Elymus : we have 

 therefore removed it, but have placed it in a separate section. 



** Lateral spikelets neuter ^ middle one perfect, 



2. H.pratense Huds. (Meadow J5-); all the glumes setaceous 

 and scabrous (not ciliated), outer glumella of the middle spike- 

 lets about as long as its awn, of the lateral ones with a short 

 awn. JE. B. t. 409: Parn. Gr. t. 11.
