'5-nerved or ribbed for its whole length, having a small tuft of hairs

i/j'^?' Panicle lax. Sjnkelets mucli compressed, ovate or deltoid, 



•with 3 — 8 closely imbricated florets. Glumes 2, nearly equal, 

 broad, much shorter than the spikelet. Glumellas 2, awnless : 

 outer cymbiform, obtuse, at length coriaceous and rounded on 

 the back below, with a scarious margin ; inner small and flat. 

 Caryopsis adnate with the glumellas, — Name : /3pi^a, some kind 

 of corn ; probably from jSpiOw^ to droop or bend down^ as do the 

 ■spikelets, which are most delicately suspended, 



1. B. media L. (common Q.) ; spikelets broadly ovate of about 

 7 florets, glumes shorter than the lowermost florets, llgule trun- 

 cate or obtuse usually very short. JE. B. t. 340: Parn. Gr. 

 t 30. 



r^jgj [ '- Meadows and pastures, frequent. I/.. 6. — Whole plant very 



elegant. Culms slender, 1 ft. or more high. 'Leaves short, linear- 

 .acuminate. Branches of t\\Q panicle thread-shaped, divaricating, purple. 

 Spikelets tremulous with the slightest breeze, very smooth, shinin^i^, 

 purple, more or less green or greenish-white at the edges. Glumes 

 ■very concave, subcompressed. Outer glumella much like the glumes^ 

 inner one minute, resembling a flat scale.- 



"^' ' 2. B. minor L, {small Q.) ; spikelets triangular about 7- 



'^^^' ' flowered, glumes longer than the florets, ligule elongated lan-

 ck, ( subsecund, Spikelets with 3 or more florets, compressed, with- 



tlie out a bractea at the base. Glumes 2, unequal, shorter than the 



spikelet; lower one keeled. Glumellas 2; outer one keeled, 

 and ciliated at the back, 5-nerved, lanceolate, with a short 

 bristle close to the point, inclosing the caryopsis, — ^^Except in 

 habit, this genus is scarcely distinguishable from Poa^ Koeleria^ 

 and Festuca, — ISTame: SaKrvXoc^ ^finger.
