356 GRASS TAMILT. 



viz. Hiek6chloa roreXlis, Seneca or Holt-GraSS, being' rare) : low, 

 slender, soft and smooth ; the pale brown or greenish spikelets crowded in an 

 evident spike-like panicle ;.each composed of a pair of thin very unequal glumes, 

 above and within these a pair of obcordate or 2-lobed hairy empty palets, one 

 with a bent awn from near its base, the other with a shorter awn higher up ; 

 above and within these a pair of very small smooth and roundish palets, of 

 parchment-like texture, enclosing 2 stamens and the 2-styled pistil, finally in- 

 vesting the grain, y. 



Alopectirus prat^nsis. Meadow Foxtaii.. Introduced from Europe 

 abundantly into meadows B. : flowering in spring; stem about 2° high, bearing 

 few pale soft leaves, terminated by a cylindrical soft and dense spike, or what 

 seems to be so, for the spikelets are really borne on short side branches, not on 

 the main axis ; these spikelets very flat contrary to the glumes, which are con- 

 duplicate, united by their edges towards the base, keeled, fringed-ciliate on the 

 keel; these enclose a single conduplicate lower palet (the upper one wholly 

 wanting) which bears a long awn from below the middle of the back, and sur- 

 rounds 3 stamens and the pistil. 



* * Awn, if any, from the apex of the glumes or palets. 



1- Spikelets densely crowded in a long perfectly cylindrical apparent spike, each spike- 

 let strictly l-flowered : glumes 2, keeled and nearly conduplicate, awn-pmnted, 

 much larger and of firmer texture than the thin and truncate awnless palets. 



Phlfeum prat^nse. Cat-tail Grass, Timothy, or Herd's Grass ; 

 introduced from Eu. ; a coarse but most valuable meadow grass, 2° -4° high, 

 with green roughish spike 3' - 8' long ; the small spikelets are crowded on very 

 Bhort branches, and therefore the seeming spike is not a true one. y, 



■*- -1- Spikelets stHctly spiked all on one side of a flattened jointless rhachis, much 

 crowded: the 2- b spikes digitate, i. e. all on the apex of the flowering stem : 

 palets awnless. Finger-grass might be sought here ;• see Panicum below, 



+* Flower only one to each spikelel, and a mere rudiment beyond it, awnless. 



Cip'nodon D^otylon, Bermuda or Scutch Grass. An introduced weed 

 chiefly S., where it is useful in sandy soil, where a better grass is not to 

 be had; creeping extensively, the rigid creeping stems with short flatfish 

 leaves and sending up flowering shoots a few inches high, bearing the 3-5 slender 

 spikes, y. 



*+ *+ Flowers 3-5 or more in each spikdet, the uppermost generally imperfect .• 

 seed loose, proportionally targe, rough-wrinkled. (T) 



Eleusine Indiea, Crab-Grass, Yard-Grass, Dog's-taii., or Wire- 

 Grass. Introduced only in yai-ds or lawns N., more abundant S., where it is 

 valuable for cattle ; low, spreading over the ground, pale ; glumes and palets 

 pointless. 



Daotyloctfenium .ffigyptiactun, Egyptian Grass. Yards and fields, 

 chiefly a weed, S. : creeping over the ground, low ; spikes dense and thickish ; 

 glumes flattened laterally and keeled, one of them awn-pointed, the strongly 

 keeled boat-shaped lower palet also pointed. 



•I- 1- ■<- Spikelets spiked alternately on opposite sides of a zigzag jointed rhachis. 

 ++ Glume only one to the solitary spikelel, which stands edgewise. 



Ii61ium per6nne, Darnel, Eye-Grass, or Ray Grass. Introduced 

 from Europe : a good pasture-grass, 1°- 2° high, with loose spike 5' -6' Jong, 

 of 12 or more about 7-flowered spikelets placed edgewise, so that one row of 

 flowers is next the glume, the other next the rhachis ; lower palet short-awued 

 or awnless. 



++ Glumes a pair to the single spikdet, right and left at each joint oftlie rhachis. 



Tritieum r6pens, Couch-Grass, Quitch or Quick-Grass, &c., belongs 

 to the section with perennial roots ; this spreads amazingly by its vijforous 

 long running rootstooks, is a pest in cultivated fields, and is too coarse and
