centre of the gibbous (not triangular) outer side, which fails to reach 

 the beak, and is, in fact, only the central nerve or rib, not more dis- 

 tinct or prominent than the lateral ones ; * whilst on the outer side of 

 the beak, I perceive only an occasional thickening, now and then 

 forming a slight ridge, hardly to be called a wing, and as often or 

 oftener obsolete as present Again, 1 find the (fully ripe) perigynes 

 by no means " obscurely many-nerved," but, on the contrary, that the 

 nerves are for the most part very distinct, prominent, and rib-like on 

 both sides at the base, vanishing at different distances in their course 

 upwards towards the beak, into which, or nearly so, one or more of the 

 central nerves very commonly extends. The densely tufted and 

 matted fibres of the roots form, with the soil which they bind into a 

 firm mass with their own substance, large conical mounds, often seve- 

 ral feet in height, used, it is said, in some English counties for has- 

 socks, and serving as stepping-stones, enable the botanist to traverse 

 the boggy thickets with dry feet. The long tough culms are employed 

 in this island as a cheap though inferior substitute for straw, in 

 thatching ricks, &c, occasionally.
