The Rev. Dr. William Richardson has introduced this variety 

 of the Agrostis slolonij'era to the agricultural world under the name 

 of Fiorin, and has shewn its merits and properties, deduced from 

 his own experiments, in a variety of publications on the sul)ject, 

 to which the reader is referred. It is greatly superior, in point of 

 produce and nutritive powers, to the other varieties of the Agr^alia 

 stoloriifera which have been enumerated ; this will be manifest on 

 referring to the details of experiments made upon them, as given 

 under the head of grasses natural to moist soils. 



On comparing the specimens of these different varieties, their 

 resemblance to each other is so great, that they may be easily 

 mistaken for each other, without a close inspection, and some 

 knowledge of botany to assist it. It was before observed, that this 

 variety (larger creeping bent or fiorin) appears to be confined to 

 rich ancient pasture land as its natural place of growth, and 

 the other varieties to various soils and situations ; and that vviien 

 taken from these different soils, and cultivated together under 

 the same circumstances, they retain the discriminating characters 

 before mentioned. 



On damp clayey soils the second variety is the most common 

 grass. To moors and bog soils the third variety is chiefly, or (at 

 least according to my observations) altogether confined. To light 

 sandy soils, particularly when more or less shaded, the fourth va- 

 riety is peculiar ; and the fifth variety is seldom found but in the 

 bottom of ditches, or by the sides of rivulets. The first variety 

 being therefore scarce, and the otlu rs very common, there is litth; 

 room for surprise at the contradictory results of experiments that 

 have been made on one or other of these inferior varieties, by 

 Gentlemen equally eminent for agricultural knowledge, under the 

 conviction of their being one and the same grass as recommended 

 by Dr. Richardson, under the name of fiorin ; whereas, though
