other. The naked seed is linear-oblong, tapering to a 

 point at each end, the upper end the narrowest. Not 

 subject to disease. 

 liefer. 1. Seed of the natural size. 



1. The same magnified, exhibiting the concave side of 



the seed. 



2. Magnified, exhibiting the convex side of the seed. 

 Fig. 3. Eriophorum vaginatum, sheathed cotton-grass. 



The long w^hite hairs attached to the seed of the different 

 species of cotton-grass, particularly distinguish it ; the 

 body of the seed is three-cornered. 

 Kefer. 1. Seed of the natural size.

2. View of the interior side of the seed, with its long 



woolly hairs. 

 Fig. 4. Phalaris canariensis, canary-grass. 



The seed is covered with the husks of the blossom 

 like a crust, nor open : from a round it becomes tapering 

 to a point at each end ; surface smooth and glossy. 

 Refer. 1. Husks and seed. 



2. Seed the natural size. 

 2. The same magnified. 

 Fig. 5. Phleum pratetise, meadow cat's-tail-grass. 



The seed is loosely covered with the husks, which 

 separate from it in cleaning ; the naked seed, as shewn 

 at 2, 2, fig. 5, is roundish, and very small. The two 

 valves which form the husks or seed-vessel are furnished 

 with white straight hairs on the back : they also ter- 

 minate with two dagger-like points, which afford a good 

 character of distinction between this and the seed of 

 fox-tail-grass (Alopecurus). 

 Refer. 1. Seed enclosed by the husk. 



1. The same magnified, shews, more clearly than the 



natural size, the fringes of hairs, which gradually 

 terminate towards the middle of the dagger-like 

 points ; while in the spurious cat's-tail the fringes 

 terminate abruptly before they reach the origin of 

 these points. See fig. 27. — No. 1. 



2. The naked seed, roundish, of the natural size. 

 2. The same magnified.
