12 ALOPE GURUS AGRESTIS. 



ovate-oblong, and having two green ribs on each side. Awn lengthy, 

 slender, commencing slightly above the base of the palea, and extend- 

 ing considerably beyond it. 



Filaments three in number, slender. Anthers protruding, each end 

 notched. Styles united and short. Stigmas long, downy, and two in 

 number. Stem circular, upright, slender, rough, bearing three or four 

 leaves, with rough, striated, swollen sheaths, upper sheath carrying at 

 its apex a blunt downy ligule, and being longer than its leaf. Joints 

 smooth. Leaves flat, rough, striated, and acute. Inflorescence simple, 

 panicled. Length from one to two feet. Root small, fibrous, annual. 



This species is easily known by its attenuated panicles, which are 

 often purplish in colour; and by the rough stem and sheaths, and the 

 long dorsal awn. 



Dr. Parnell mentions that it can be recognised from A. pratensis in 

 the slenderness of the panicle, in the spikelets being larger, the ligules 

 considerably longer, the roughness of the stem and sheaths, and in the 

 keels of the calyx being but slightly hairy; whilst in A. pratensis the 

 ligule is short and blunt, keels of calyx and lateral ribs having long 

 hairs, and the stem and sheaths being quite smooth. In A. geniculatus 

 the stem and sheaths are also smooth, the awns shorter, the spikelets 

 less, ligule shorter, calyx less acute and different in shape, and the 

 panicle not so tapering. In A. fulvus the stem and sheaths are 

 smooth, the panicle less tapering, spikelets less, ligule shorter. 



Flowers in the first week in July, and ripens its seeds in October. 



My thanks are due to Mr. Joseph Sidebotham, of Manchester, and 

 to Dr. Wilson for good specimens of this Grass.
