The produce of the space, ditto 



The produce of foliage in the spring from this grass, is comparatively nothing, as is the case ' 

 with the latter-math produce. The root leaves are remarkably short in this species of Canary- 

 grass, and the culms are numerous. At the time of flovrering, the produce may he said to con- 

 sist entirely of culms. It grows naturally in diy sandy places ; said to have been first discovered 

 in Great Britain by Mr. Woodward and Mr. Crow, near Swaffham, Norfolk, in 1780. It is also 

 a native of Germany, where it grows in pastures, orchards, hills, and dry sandy barren places. 

 It is evidently unfit for cultivation in the farm, as the above produce constitutes what it yields 

 in one season, and which, when compared to that of most other grasses affecting a similar' 

 soil, proves greatly inferior. It ripens plenty of seed for its propagation. It thrives best on a ' 

 sandy loam. The structure of the panicle is useful, to shew the last form of a panicle next to a 

 spike. In this it appears a spike, until pressed by the fingers ; it then proves to be a panicle. 

 It flowers in July, and the seed is ripe in the beginning of September. 



Pestuca 



Foxtail-like Fescue-g 



Bromus alopecurus. Bonn's Catalogue. 



Specific character: Spike erect, attenuated ; calyx-valves very unequal, outer large, three- 

 nerved, acuminate, inner very minute, awl-shaped ; corolla, outer valve awned, pubescent 

 at the edges ; inner, two-nerved, slightly ciliate on the nerves. 



Ohs.~l can find no specific description of this grass. I received the seeds from Mr. Donn, 

 and there is therefore no doubt of its being the Bromus Alopecurus of the Cambridge Ca- 

 talogue. It proves to be a Festuca. Culms smooth, upright ; leaves linear, channelled, or 

 doubled together like those of the ^.e«a ^.«,,,,-,^ and like them, slightly glaucous, smooth; 

 sheath smooth, furrowed, sheath-scale minute lacerated ;_spike mostly facing one way, up- 

 right;— palvx lO-flowered, terminatina: floret Ko.... . i „„i...f tl,. Wnssom furnished
