A SURVKY OF THE LOWER TKES MARSHES 137 



For the lowland plant I suggest the name 7'elictus. 



Glaux marttima next claims our attention. The reader 

 will have perceived that it thrusts itself upon one everywhere 

 in Saltholme and the Saltmarshes ; in water and out of it, 

 nothing seems to inconvenience it, and soil long since 

 deprived of even a modicum of salt satisfies it as well as the 

 saltiest of salty water, although in the latter habitat it assumes 

 a long ragged-looking habit. No other halophyte shows any 

 such adaptive possibilities as this save perhaps, to a very 

 slight degree, Carex distans and Triglochin maritimnin ; even 

 Armeria maritima and Plantago man'tima, recurring in the far 

 west of Durham, show no tendencies like these to transgress 

 their limits here. 



As, we have already seen, the prevalence of Orchidaceae at 

 Billingham is quite remarkable; nowhere else in Durham have 

 I seen such a plethora of forms. Even yet the related genera 

 Orchis and Gymnadem'a, with their various forms and hybrids, 

 will amply repay study, as my discovery of Orchis incarnata, 

 Gymnadenia densiflora and the hybrids previously recorded 

 demonstrates. Helleborine palnstris, now extinct at Blackball 

 Rocks, still draws our attention in the Trollius Marsh, and 

 long ere its detection I had predicted its occurrence with other 

 forms which will yet appear. 



The same marsh can yet boast of Thalictrum flavum, 

 another plant lost in many of its former stations, and there, 

 too, the form rufinerve can be found ; this likewise was a 

 welcome reappearance long despaired of. I have a record for 

 1901 on the banks of the Team at Lamesley but that, as many 

 other old habitats, will see it no more. 



Floristically, it will be seen that my results have surpassed 

 one's wildest hopes aroused by the rediscovery of Trollius. 

 Independent of any influence of my Yorkshire experiences, 

 my ambitions were toned down by the knowledge of the 

 futility of efforts parallel to endeavouring to repeat Brewster's 

 record of Salicornia etiropaea in Saltholme Marsh, or of the 

 same plant at Samphire (I) Point. Not therefore expecting 

 great things, correspondingly greater has been the surprise.
