Cheiio podium album, L. 



Atriplex annustifolia, Sm. 



Riunex coiKjlomeratua, Murr. 



R. obtimfolhts, Auct.

 this district.

[I have never noticed any member of the Euphorbiacea on the 

 Moor.] 



Ulmus montana, Sm. — Planted. 



Quercus Robur, L. 



Y Si>Y. pedunculata, ^hrh. — A form of scrub oak is native and 

 plentiful in most of the Lancashire doughs or dales. There is 

 evidence that this oak likewise abounded formerly in the clough 

 through which Singleton Brook runs. Indeed, the name Kersal 

 would appear to signify oak-grove. 



Fayus sylvatica, L., Corylus Avellana, L., Alnus glutinosa, L., 

 Betula alba, L., Populus nigra, L., P. tremula, L. — All these trees 

 occur either on the Moor or in its immediate neighbourhood.

S. cinerea, L. 



8. Capj'ea, Li. 



Sparganium ramosum, Huds. — Abundant and very fine by 

 Singleton Brook.

 Moor, in hedge skirting the road to Rainsough village.

P. pusillus, L. 



Triglochin palustre, L. — Boggy parts of the moor by Singleton 

 Brook. 



Alisma Plantago, L. — This plant holds its own almost into the 

 very heart of Manchester, wherever there is a piece of water, 

 however stagnant. It is especially frequent in the brickfields, &c., 

 towards Oldham and elsewhere. 



Elodea canadensis, Mich. — Reservoir, Bleackley's Works, bor- 

 dering on the Moor. 



Crocus vermis. All. — Very sparingly, and perhaps extinct on 

 the Prestwich hills bordering the Moor. 



C. nudiJloruH, Sm. — Most abundant, and a characteristic plant 

 of the locality in the meadow land by Singleton Brook, and also 

 more rarely by Bleackley's Works.
