A HISTORY OF NORFOLK 



its bed soil, its temperature, its depth, its flow. A large herbarium may 

 be made of these varying forms. 



The Characese have, as has been said before, one determined 

 characteristic. They object to share their home with any other plant. 

 ' All or nothing ' is their maxim. As soon as other aquatics begin to 

 assert their existence in the ditch, drain or pool, occupied by Charas 

 they retire, and only appear again when spade and shovel have effected a 

 thorough cleaning out of the old home. 



The plants recorded in the following census have been verified by 

 Messrs. H. and J. Groves, to whose labours and investigations we owe 

 almost all that English botanists know of this interesting Order of sub- 

 merged aquatics.

MOSSES (Musci) 



The literature relating to the mosses of Norfolk is extremely scanty. 

 It is confined, indeed, as far as can be ascertained, almost solely to the 

 following three lists : — 



(i) A list of mosses, with localities, in the Sketch of the Natural 

 History of Yarmouth and its Neighbourhood, by C. J. and James Paget, i 834. 



(2) An unlocalised list of species in the Rev. Geo. Munford's List 

 of the Botanical Productions known or reported to inhabit the County of Norfolk, 

 1864. 



(3) A similar list by Miss A. M. Barnard, compiled for Geldart's 

 article on Botany in Mason's History of Norfolk. 



The two later lists are based very greatly on the first ; and Miss 

 Barnard's list, though compiled many years later, adds very little to what is 

 already recorded in the others ; for practical purposes we may therefore say 

 that during the latter half of the century bryological investigation has been 

 at a standstill. In fact, with the exception of a few scattered records, the 

 only available material additional to these lists consists of two or three 

 collections made within the last year or two, viz. : {a) A list of mosses 

 collected in east Norfolk, in 1898 and 1899, by Mr. W. H. Burrell, 

 comprising about 50 species, {b) A collection of about 30 species (kindly 

 made for the purposes of this article) principally from the neighbourhood 

 of Hunstanton, by Mr J. W. Bodger, in 1900. {c) A collection similarly 

 made bv Mr. E. M. Holmes, mostly in the neighbourhood of Holt, in
