In sandy cultivated fields, but rare. 



In Ray's time it was found at Great Witehingham, Norfolk, and 

 about Elden, Suffolk, by Thomas Willisell. Hudson found it 

 near Guildford. There are specimens in Lightfoot's herbarium, 

 gathered near Brandon, Norfolk, and at Henham, Suffolk. Bat- 

 tersea fields have long been known to produce this grass, which 

 is indubitably a native, though, like all annual plants, variable 

 in its places of growth. 



Annual. July, August. 



Boot fibrous. Stems numerous, bent and decumbent at the base, 

 then ascending, about a foot long, jointed, leafy, striated, smooth. 

 Leaves broacCpointed, striated, wavy at the edges, besprinkled, 

 like their long rather swelling sheaths, with little warts, many 

 of which bear bristly hairs. Spikes from 3 to 8, alternate, spread- 

 ing, crowded at the top of the stem, many-flowered. Common 

 stalk of each spike flat, wavy, winged, rough-edged, with a flat 

 mid-rib at one side, the other beset with 2 rows of unequally 

 cloven, two-flowered, short, erect partial-stalks. Fl. dark pur- 

 plish, erect, elliptic-oblong. Largest valve of the calyx with 

 usually five ribs, its edges rough or downy. Stigmas, and often 

 Anthers, violet coloured. The specific name is said to have ori- 

 ginated in the use made of this grass in Germany, which is to 

 procure bleeding of the nose, by thrusting its spikes up the 

 nostrils. 



Professor Schrader separates from this species, by the name of 

 Syntherisma glabrum, what Leers has described, and represented 

 in his t. 2./. 6. I describe the native English plant, upon which 

 Haller evidently founded his Digitaria. Jussieu copied him, even 

 in his error respecting the character ; nor did he advert to the 

 bivalve corolla, pointed out by Haller himself, in Panicum Dac- 

 tylon, which forms an exception to their definition of Digitaria. 

 1 have therefore concurred with Mr. Brown and other able bota- 

 nists, in applying the name of Cynodon to the preceding genus, 

 retaining Digitaria for this. The advanced state of our know- 

 ledge requires the separation of both from Panicum, with whose 

 character they have never been found. well to accord.
