it protrudes out of the calyx ; it is also twisted and knee- 

 bent, like that of an Avena. The panicle of the lanatus is 

 generally of a reddish purple colour, tinged with green, or, 

 when growing under the shade of trees, of a whitish green 

 colour. The panicle of the H. mollis is always of a pale 

 whitish green colour.

The weight of nutritive matter which is lost by leav-

 half of its value, is - - - 1238 15 3 



The proportional value in which the grass of the flowering crop 

 exceeds that of the seed crop is as 9 to 7. 



64 dr. of the roots afford of nutritive matter 5 dr. 2 qr. The 

 nutritive powers of the roots are therefore superior to those of the 

 grass of the flowering crop as 11 to 9, and also superior to the 

 grass of the seeding crop as 11 to 7. 



The above details prove this grass to have merits which, when 

 compared with those of other species, rank it as one of the supe- 

 rior grasses ; but then it produces little herbage in the spring, 

 and the latter-math is next to nothing. It is also a very late 

 grass, and whatever merit it may possess with regard to a crop, at 

 the time of flowering, it can only be taken into the account in re- 

 lation to the soil which naturally produces it, which is a liglit
