The Na^tukaltst. 



possible til at I may have overlooked a plant or two, it is not probable 

 that a further search would make any important addition to the list 

 which I give. Of the plants mentioned in my former paper, some 

 seem to require such decidedly maritime conditions for their develop- 

 ment, that they do not appear above Grimsby ; of the rest, the 

 highest stations ascertained are the following : — CaJcile maritima, 

 Triticum junceum, Great Coates : Statice Limonium, Suoeda maritimaj 

 Killingholme : Armeria maritima, Triticum repens, var. litioralis, 

 Hordeum maritimum^ Atriplex littoralis, Goxhill : Artemisia mari- 

 tima, New Holland : Spergularia marginata (Syme), Ferriby : Leptu- 

 rus fiUformis, Winteringham : Spergularia neglecta (Syme), Plantago 

 maritima, Trlglochin maritimum, Sclerochloa maritima, Alkbro : 

 Gla.ux maritima, Juncus Gerardi, Sclerochlea distans, Keadby : Aster 

 IVipolium,, Burringham : Apium graveolens, Scirpus maritimus, Sus- 

 worth : Rumex maritimus, Ferry Flash. 



Of quasi-maritime plants, Trifolium fragiferum occurs about Keadby 

 and Burringham, Samolus Valerandi in the neighbourhood of Owston 

 and Haxey, and Flantago coronopus at Burton Stather ; to none of 

 these three, however, does salt water seem to be a necessary of life? 

 as they are frequently seen at considerable distances from either the 

 sea or tidal rivers. As on the Ouse, so on the Trent, the three 

 really maritime plants that ascend highest are, Rumex maritimus, 

 Apium graveolens, and Scirpus maritimus ; the last-named, however, 

 was not flowering at Susworth, and seemed to be dying out. Between 

 Owston Ferry and Gainsborough, none of the above-named plants 

 were noticed ; the following growing very luxuriantly, and occupying 

 all available room on the banks : — Ranunculus repens, R. sceleratus. 

 Geranium pratense, Spirota ulmaria, Angelica sylvestris, Valeriana 

 oficinalis, Dipsacus sylvestris, Tanacetum vulgare, Petasites vulgaris, 

 Arctium ma jus (Schk.), Arundo Fhragmites, Salix viminalis, and 

 twining about amongst them and over them. Convolvulus sepium, with 

 its large white flowers. 



Eoughly speaking, the distance from Grimsby at the Humber 

 mouth to Goxhill, at the north-east corner of Lincolnshire, is 15 

 miles — from Goxhill to Alkbro, near the Trent falls, 20 miles — and 

 from Trent falls to Owston Ferry 20 miles more ; from which 

 it appears that a few maritime plants are to be found at least 50 

 miles from the sea-coast, not strictly speaking inland, but on the 

 "banks of a tidal river, at that distance from the sea.
