Jasione montana is another Dene-plant. This species is partial 

 to sand of all sovts ; but it grows more luxuriantly in the richer 

 soil of Cheshire. 



Lotus corniculatus would not appear in any list of plantm ra- 

 riores, only about Yarmouth — where the uniformity and poverty 

 of the soil diminish the number of the species — every plant is 

 worthy of observation. 



Ranunculus Flammula grows about the edges of shallow grassy 

 pools, often accompanied with Helosciadtum nodifiorum, H. re- 

 pens?, and H. inundaium. 



Rhinanthus Crista-Galji appearsi^as^a^ larger form or with a 

 larger flower on the sand-hills about Caistor, than it usually 

 bears when it appears on rich meadows. Itjljiearly as conspi- 

 cu ous as the form v.liicli i^rcrws jn^jyieXiiMQln_shire^ fens, and 

 which_js called a sjjexdesjindjdi gniiied with th e epithet great. 



The sand-hills about Caistor are covered with Aira canescens 

 {Corynephorus canescens). This with Triticum junceum and Ely- 

 mus arenarius constitute the grassy covering of these Dunes 

 (Denes) . 



The rarest plant we observed was Teesdalia nudicaulis, in 

 fruit. It appeared only in one place, about halfway between 

 Yarmouth and Caistor. Near it we saw a single plant or so of 

 Thalictrum minus (?), or what would have passed muster for this 

 species a score of years ago. 



Sisymbrium Sophia was very abundant on the turf fences 

 skirting the Denes. 



Vicia lathyroides is another of the scarce plants of this tract. 

 It was so scarce that we only saw a single specimen ; but 

 our visit was rather later than the usual flowering period of this 

 Vetch. 



Sedum anglicum was plentiful in many parts of the coast, and 

 especially near Caistor. • It was far from unfrequent on the 

 shores of Suffolk ; aud it was found nearly thirty years ago on 

 the sandy shore of Mersea Island, Essex. In Ray's ' Synopsis,' 

 Dillenius's edition, page 270, it is localized, "in sterilioribus Suf- 

 folcise, itinere a Yarmouth ad Donewich (between Yarmouth and 

 Dunwich). In litore raarino prope i?r«A;e/sAam (sea- coast near, 

 etc ) ." Plantago Coronopus is one of the commonest of the Dene 

 plants, 



Frankenia Icsvis, which in former times, viz. in 1823, abounded
