racliis, with 3 or more perfect florets. Glumes solitary, or 2 Avith 



the one next the rachis small ; outer with several nerves, as long- 



or longer than the lowest contiguous floret, ° 



40. Lepturus. Spike simple, cylindrical. Spikelets solitary in each 



joint imbedded in alternate cavities on opposite sides of the rachis 

 and placed edgewise to it. Glumes 2, coriaceous, collateral on the 

 outside of the cavity 'and covering it. 

 Knappia. Spikelets shortly stalked, solitary, arranged on two sides 

 of the simple rachis and forming a simple unilateral spike-like 

 raceme, 1 -flowered, awnless. Glumes 2, opposite, truncate, nearly 

 equal, rather longer than the floret, membranaceous, 1 -nerved. 

 Outer glumella hairy, membranaceous, jagged; inner sometimes 

 wanting. 



Spikelets (with 1 perfect flower) arranged only on one side of the partial 

 rachisy and forming a racemose or digitate compound spike or raceme, 



Spartina. Partial spikes erect. Spikelets sessile, lateral^ com- 

 pressed, with scarcely any rudimentary neuter floret. Glumes 

 very unequal. Glumellas compressed, lanceolate, acuminate. 

 Styles united to near the middle. Stigmas elongated. 



43. Cynodox. Partial spikes spreading. Spikelets almost sessile, 



laterally compressed, with a rudimentaiy neuter floret. Glumes 

 nearly equal. Glumellas compressed ; outer one cymbiform. Stjdes 

 distinct. Stigmas oval. 



44. DiGiTAKiA. Partial spikes spreading. Spikelets in pairs on short 



unequal pedicels, fiat in front, rounded on the back, with a neuter 

 floret in front as large as the perfect one. Styles distinct.

Panicle spiked, Spikelets with 1 perfect central floret, and 

 two outer larger neuter ones. Glumes 2, very unequal ; upper

 neuter florets single, awned. — Name:

 5, 6. — A foot high, its agreeable smell in the act of drying, like 

 that of Woodruff (A sperula odorata), gives the well-known scent to 

 new-made hay. Leaves short. Panicle compact, spiked, yellow in 



Glumes very unequal. Mr. Brown first pointed out the true 

 structure of the spikelets of this genus : previously the two neuter 

 florets were considered by some an inner pair of glumes, by others
