 smaller, erect, or erect-patent, often purplish. From this, B. tectorum 

 (introduced near the new mill at Hoddesdon, Hertfordshire) is prin- 

 cipally distinguished by the unilateral droopingpanicle, and the outer 

 glumella much longer than the inner one.

 floret equal to the larger glume, leaves downy on both sides.

On the sands of St, Aubin's Bay, the Greve d'Azette and the

 larger glume being as long us the adjacent glumella, the conspicuous 

 equidistant 7 nerves to the glumella, and "by a sharp conical point 

 aj the base of the florets." Parn. Stamens often only 2.
