34. SPARTl'NA. CORD-GRASS. 



Calyx one-flowered, of two unequal, lance-shaped, keeled, com- 

 pressed chaff-scales; the inner cleft at the end. Corolla of two 

 lance-shaped, bluntish, compressed, awnless husks, the inner 

 rather longer. Nectaries none. Filaments hair-like, not so long 

 as the corolla; anthers erect, linear, cleft at the base. Germen 

 elliptical. Styles united for a great part of their length, separate 

 at the top ; stigmas feathery, slender. Seed oblong, compressed, 

 loose, covered by the unaltered husk. Named from its resem- 

 blance to Lygeum Spartum. 50. 



1. S. stricta. Twin-spiked Cord-grass. Spikes two or three ; flowers 

 very hairy ; leaves shorter than the spikes, tapering at the base, and 



jointed upon the sheath. Root creeping : the whole plant remarkably 



stiff: straw a foot or more in height: spikes erect, straight, close toge- 

 ther. Perennial : flowers in August : grows in muddy salt marshes on 

 the east and south-east coasts of England : rare. Eng. Bot. vol. vi. 

 pi. 389. Eng. Fl. vol. i. p. 136. 168. 



2. S. alternifolia. Many-spiked Cord-grass. Spikes numerous, flowers 

 glabrous ; leaves equal to or longer than the spikes, dilated at the base 



and continuous with the sheath. Much taller than the preceding. 



Perennial : flowers in August : grows in muddy salt marshes : extremely 

 rare. Discovered in 1836 by Dr. Bromfield, at Itchen Ferry, South-

 35. CYNOSU'RUS. DOG'S-TAIL-GRASS. 



Spikelets in pairs: the outer consisting of numerous two-rowed, 

 lance-shaped, pointed chaff-scales, without corolla or other part 

 of fructification, and resembling a pectinated bractea; the inner 

 of several flowers. Calyx of two equal, lance-shaped, one-ribbed, 

 concave, keeled, taper-pointed, awned chaff-scales, containing 

 two or three perfect flowers, occasionally with rudiments of more. 

 Corolla of two unequal, lance-shaped husks ; the outer concave, 

 keeled, with a straight awn at the summit; the inner two-ribbed, 

 inflected at the edges, cleft at the point, awnless. Nectary of two 

 acute scales. Filaments hair-like, shorter than the corolla ; anthers 

 linear, cleft at both ends. Germen elliptical. Style very short, 

 distinct ; stigmas long, feathery. Seed loose, oblong, invested 

 by the unaltered husks. Named from kyon, a dog, and oura, a 

 tail. 51. 



1. C. cristatws. Crested Dog's-tail-grass. Spike simple, linear ; neu- 

 tral spikelet awnless.- Straws about a foot high, stiff, smooth : spike 

 erect, linear, with a waved rough stalk. This grass is excellently adapted 

 for making straw-plait, and has been employed for that purpose. Cattle 

 hardly ever eat it. Perennial : flowers in July : grows in meadows 

 and pastures, abundantly. Eng. Bot. vol. v. pi. 316. Eng. FL vol. i. 

 p. 137. 170. 



2. C.echinutus. Rough Dog's-tail-grass. Spike compound, egg-shaped ; 



neutral spikelet awned. Straws from ten to twenty inches high ; 



spike dense, bristly with the long rough awns of the perfect flowers.
