BOTANY 



THE LIVERWORTS {Hepatic^) 



When we consider the elegance of form, variety of hue, and curious 

 structure of many of the Hepatics, classified by the botanists of the last 

 century with the mosses to which they are nearly allied, one wonders at 

 first why they have not been more studied. The chief reason perhaps 

 is the difficulty of finding them in fruit, a circumstance which I have 

 frequently experienced. They occur chiefly on damp soil, in bogs or on 

 old trunks of trees. Hence those who knew best our Sussex forests have 

 given them most attention. This group comprises Marchantia, Junger- 

 mannia, Riccia and Anthoceros, all of which are represented in Sussex. 

 In this county they have been most fully examined by the Rev. E. N, 

 Bloomfield, of Guestling, whose list with a few additions I here subjoin. 

 The list is arranged according to Dr. Cooke's Handbook of the British 

 Hepaticce, 1894.

FRESHWATER ALG^E 



Although considerable attention has been paid to the Sussex fresh- 

 water algae in several of the districts, the county with respect to them 

 has been by no means thoroughly explored. In his Flora of Tiinbridge 

 Wells and the Surrounding Country., Mr. E. Jenner has given a list of 

 those which occur in the Medway district, with their localities, and as 

 these include Ashdown Forest, Waterdown Forest and the commons, 

 bogs, streams and ponds therein, it is very useful for reference. Zygnema 

 Hasseli and Z. Jenneri are first recorded from this county, the latter at 

 Mark Cross. In his Flora of Hastings, the Rev, E. N. Bloomfield 

 published a list of those in the East Rother district, which includes divers
