BOTANY 



for folypella glomerata Leonh. are Plumstead Marshes and Folkestone Warren ; the scarce 

 1. frolifera Leonh. being restricted to ditches near Snodland. Nitella flexilis Agardh, 

 collected once near West Peckham, and TV. opaca Agardh, from six stations in districts 7, 8 

 and 9, complete our somewhat meagre list. 



LICHENS (Lichenes). 

 The lichen flora of Kent is peculiar in relation to subalpine species, which are mostly 

 confined to the district known as Lydd Beach. These probably have grown from spores 

 carried by the wind from Devon, or from the opposite French coast. 



The published records of lichens for Kent are comparatively few. Many of those given by 

 Foster and Jenner, in the Flora of Tunbridge Wells, have now disappeared, and the list given 

 by the present writer in the Journal of Botany for 1888 has since had little added to it. 



In the following list the rarer species are marked with an asterisk. The classification 

 adopted is that of Crombie's British Lichens as far as the genus Pertusaria, and beyond that 

 genus, that of the third edition of Leighton's Lichen Flora of Great Britain.
