satellite, Crepis paludosa. Of the orchids, O. incarnata 

 vanishes, and O. maculata becomes less usual, although 

 Helleborine palustris, Listera ovata, Gyinnadenia coiwpsea (in 

 descending order of frequency) still flourish, and so too does 

 Faniassius palustris. 



In all parts of the marsh previously studied, a remarkable 

 absence of the common Ramincnbis pianwiula strikes one as 

 peculiar, yet here it makes a belated appearance in small — 

 very small — quantity, just enough to force more clearly upon 

 one its failure elsewhere. Triglochin palustre, likewise sparingly 

 found in the eastern upper marsh, not uncommonly thrusts 

 itself upon one, whilst Pulicaria is very plentiful.

Of the Salicetum, owing to its obviously (so to speak) faulty 

 condition, there is not much more to say than that Salix 

 caprea is certainly not now dominant, Nevertheless, in some 

 not far distant future, it will recover from the devastating 

 effects of fire, for already rejuvenescence is occuring both from 

 the old roots, and by means of a goodly stock of seedlings.
