cornia herbacea, Glaux maritima, Leptuvus incuivatus, &c. On the 

 sandy shore towards Marazion, Eryngium raaritimum, Salsola Kali, 

 Alsine peploides, Atriplex rosea, Beta maritima, Cakile maritima, 

 Carduus tenuiflorus, Convolvulus Soldanella, Glauciura luteum spa- 

 ringly. Polygonum Rail, Pyrethrum maiitimum &c. are met with. On 

 the sea cliffs, at the Logan-stone, St. Ives, &c., Daucus maritimus and 

 Crithmum maritimum grow abundantly ; I can scarcely believe that 

 the former of these plants is more than a maritime variety of Daucus 

 Carota, which is a most abundant plant in Cornwall, and appears to 

 assume a more fleshy character as it approaches the sea, as is the case 

 with many other plants ; the points of distinction are very slight, and 

 such as are likely to be caused by the effect of salt air, viz., the thick 

 leaves and short comb-like prickles on the capsules. Aster Tripo- 

 lium, Plantago maritima, Silene maritima, &c., are generally found on 

 the cliffs, and those at Newlyn produce Centranthus ruber. On the 

 western green we find Fceniculum vulgare, while on the eastern side 

 is Erodium maritimum, which is however more plentiful on St. 

 Michael's Mount ; Lavatera arborea grows on the cliffs at Mousehole. 

 Near this little fishing village is a large cave, formed in the cliff by 

 the action of the water, the lofty roof and sides of which are beauti- 

 fully festooned with luxuriant ferns of very large size ; Aspleniura 

 marinum is here most abundant, and it is not uncommon along the 

 coast. I saw it at the Logan, St. Michael's Mount, &c. Senebiera 

 didyma grows on the road-side near the wherry, and on the sands near 

 the same spot, Trifolium subterraneum is met with sparingly. The 

 very rare Cynodon Dactylon grows plentifully in many parts of the 

 green towards Marazion, particularly opposite Gulval Church ; when 

 not in flower it may readily be distinguished by its glaucous foliage 

 and creeping stems. Though the few last may not exactly belong to 

 the head of sea plants, yet as their localities are similar to those given 

 for others of that class, it seemed to be the most natural place to re- 

 fer them to. Diotis maritima, which grew here in Ray's time, has long 

 since disappeared, and Euphorbia Peplis has not been gathered for 

 several years as I am informed, and must therefore be considered lost 

 in this locality ; I carefully searched the sands and the green from 

 Marazion to Penzance, but could find no trace of it. In the bog- 

 plants, Penzance is rich, as many of the upland moors and boggy val- 

 leys present us with some very interesting species. Chyangall is one of 

 the most productive of these moors, though limited in extent ; here I 

 gathered Cicendia filiformis, Littorella lacustris, Illecebrum verticilla- 

 tum abundantly, Anagallis tenella, Peplis Portula, Isolepis fluitans,
