their removal has offered a favourable opportunity for germination ; 

 but it would be interesting for any botanist, who might be able to visit 

 the locality, to ascertain if it occurs in small quantity or in abundance, 

 and whether there is any probability of its becoming permanently 

 naturalized in this country." 



Anacharis Alsinastrum. 



u 



1 am afraid the Anacharis can hardly be considered even natu- 

 ralized, much less ' truly indigenous,' in this county. In the only 

 station yet recorded (Phytol. iv. 365), it grows at Kirby Wiske, in a 

 pond immediately beneath the garden of the Rev. R. Pulleyne, and 

 was planted there for ornament, about three years ago, in company 

 with various other British and foreign aquatics, since which it has 

 increased so rapidly as to fill up the, pond with a dense mat-work of 

 stems, which effectually prevent the growth of its less hardy neigh- 

 bours ; so that it is no longer a desirable occupant, but bids defiance 

 to all attempts to destroy it. In time of flood this pond communi- 

 cates with the river Wiske ; so that the Anacharis will most likely 

 become established along the course of the stream in process of time, 

 and thence be conveyed to some of the numerous broad ditches that 

 intersect the low meadows in the neighbourhood, which are all that 

 remains of what was once Newshara Carr." 



Serrafalcus patulus, Pail. 



" This plant appears thoroughly established, in considerable abun- 

 dance, along with Apera Spica-venti and Lolium temulentum, on the 

 disused ballast-hills at the mouth of the Tees, on the Durham side of 

 the river, some of which are now partially brought under cultivation j 

 it, however, seems entirely] absent from the deposits on the oppo- 

 site (Yorkshire) bank, many of which are of more recent formation ; 

 but its place is supplied by numerous other plants which are not of 

 frequent occurrence in the North, amongst which are Lepidium Draba 

 and L. ruderale, Sinapis alba and S. nigra, Scirpus Tabernaemontani, 

 Festuca pseudo-Myurus, Hordeum maritimum, Melilotus alba, Pasti- 

 naca sativa, Fceniculum vulgare, &c." 



Ranunculus confusus, Gr. & Godr. 



" This plant is plentiful in the salt-water ditches that intersect Coat- 

 ham marshes, and is subject to almost as many variations in habit and 

 character as its intimate ally, R. aquatilis, from which it appears 

 essentially distinguished by its slender, ovate-conic receptacle, and
