Plants, 273 



coverable in its only known British habitat, near Plymouth, 

 to which I was directed by Mr. Banks himself, and which I 

 diligently explored. I have gathered A. arv^nsis wild on the 

 Continent, where its habitats differ in condition from that 

 at Plymouth. From all I could learn, I was led to conclude 

 that the appearance of this plant, in the Plymouth habitat, 

 was purely adventitious ; and that it must, until new habitats 

 shall have been discovered, be expunged from the list of 

 native British vegetables. — W. A, Bromfeld^ M.D. Hastings^

Doronicum Vardalianches L. grows, in comparative abund- 

 ance, at Saling, near Great Bardfield, in Essex ; but it may, 

 from its situation on the bank of an old enclosure, where 

 there is an ancient mansion, have escaped from a garden 

 [either by the wind's disseminating some of the winged fruits 

 (seeds) of its discoid florets (those of its rayed florets are not 

 winged), or from some of its abundantly produced stolones 

 having been removed from the garden as rubbish]. — 17. G. 

 Lexden, M of Uh Month {April), 1834. 



Sisymbrium polycerdtium L. grows wild at the base of the walls 

 of certain streets of Bury St. Edmunds. I have forgotten its 

 origin there ; but I think that it emanated from the garden of 

 the late Sir Thomas G. Cullum, Bart. The streets in which 

 I have seen most of it are, Northgate Street, Garland Street, 

 Short Brackland, &c. ; but the cleaning efforts of the sur- 

 veyor's men do not allow so many plants as could be wished 

 to bear seeds. — J. D. 



Drosera rotundifblia L. occasionally exhibits its Flowers in an 

 expanded State, (VI. 469.) — ^Drosera rotundifolia must, un- 

 questionably, be considered a shy and capricious plant as 

 regards the expansion of its blossoms ; and we have yet to 

 learn the laws by which its motions in this respect are regu- 

 lated. That they do not depend solely on the presence or 

 absence of sunshine is quite clear; for, though I have known 

 the plant from my early boyhood, I am not quite certain that 

 I ever saw its blossoms fairly expanded till this summer. 

 Botanising, the 27th of July last, on the shores of Coleshill 

 Pool, where the Drosera grows in great profusion, I was sur- 

 prised and delighted at beholding the flowers on every plant 

 fully and beautifully expanded. The day was warm and bright, 

 but the sunshine at intervals interrupted by passing clouds : 

 the hour of the day, I think, must have been from a Httle 

 before twelve to one. In the preceding summer, about 

 July 24. to 26., I happened to have paid two visits to the 

 same spot, when the weather was equally fine and bright; 

 and on both these occasions gathered many specimens of 

 Drosera, but not a single one was to be found with its flowers
