Gen. Char. Inflorescence spiked ; spikes imbricated. Rachis 
( common receptacle) many-flowered, continuous, elongated, tooth- 
ed alternately, at each side, and flattened just above. Spikelcts 
(figs. 1 & 2.) 2 or 3 at each tooth of the rachis, parallel, 2- or 
3-flowered, all perfect. Calyx (see figs. 2 & 3.) of 2 unequal, 
upright, strap-spear-shaped, or awl-shaped, pointed or awned, more 
or less keeled glumes, both on one side of the spikelet. Corolla 
(fig. 3.) of 2, unequal, egg-spear-shaped palese ; the outermost 
largest, keeled, ribbed, pointed or awned ; the awn straight and 
terminal ; inner palea flat, cloven, inflexed at the edges, with a rib 
at each side. Nectary (fig. 5.) of 2 spear-shaped scales. Filaments 
(see fig. 3.) 3, hair-like, shorter than the corolla. Anthers strap- 
shaped, notched at each end. Germen (fig. 4.) turbinate. Styles 
(see fig. 4.) 2, distant, very short. Stigmas feathery, spreading. 
Seed (figs. 6 & 7.) strap-shaped, or spear-shaped, channelled along 
the upper side, very hairy at the summit, more or less attached to 
the unchanged paleae of the corolla. 
The 2- or many-flowered spikelets, 2 or 3 together at each tooth 
of the rachis ; and the calyx of 2 parallel glumes, 2- or 3-flowered, 
all perfect; will distinguish this from other genera, with a spiked 
inflorescence, in the same class and order. 
Three species British. 
E'LYMUS EUROPrE'US. European Lyme-grass. Wood Lyme- 
grass. Wood Barley-grass. Great Wood Rye-grass. 
Spec. Char. Leaves flat, pliant. Spike upright, compact, 
smooth. Spikelets ternate, 1- or 2-flowered. Calyx-glumes bris- 
tle-like. Florets terminated by a long awn.
