Ko. VIII. On the Vegetation of the Fens. 



As the kind of vegetation which formerly occupied the Great 

 Level of the Fens is very little known to botanists, to most of 

 whom the Fens are nearly a " terra incognita," it seems desirable 

 to give a complete list of the plants which have been recently 

 found growing in Wicken Fen. A * is appended to the names 

 of those which most abound there. The plant which forms the 

 great mass of the herbage is Cladium Mariscus, which is still 

 there regarded as a crop, although an uncultivated one.
