these seeds reached the spot on which the plants were found I am 

 quite unable to say, but would deem it not improbable that tliey had 

 been carried to the garden in water from a neighbouring pond, in 

 which I have never seen the Limosella, but to which its seeds may 

 have been borne by a flood- stream two years ago, from a more distant 

 pond, within which the plant has been repeatedly observed. The 

 alternative conjecture, that the seeds had remained dormant in the 

 soil of the garden foi- twenty or thirty years, seems less likely to be 

 the true explanation. But by whatever way the seeds contrived to 

 be on the spot in question, the fact of the Lim6sella being found as 

 a weed on cultivated ground is worthy of record, as a marked instance 

 of change from the ordinary habitat of an " aquatic " plant. — Heiaett

342. Note on Symphytum asperrimum. One fine evening last month 

 during a stroll along the banks of the river Tame, in Cheshire, I fell 

 in with a quantity of Symphytum asperrimum, apparently wild, grow- 

 ing in a meadow. There is no garden in the vicinity, from which it 

 could have escaped, indeed I have never seen it cultivated in the gar- 

 dens about here, though I am aware it is occasionally to be met with. 

 Perhaps some of your correspondents may know something about the 

 plant, and on whose authority it was placed in the Supplement to 

 Francis's Catalogue. — J. Sidehotham ; Manchester, July 7, 1843. 



343. New habitat for Lepidimn Draha. This plant is of such rare 

 occurrence, and so local, as very seldom to be brought within the reach 

 of the collecting botanist ; indeed, unless recent research has multi- 

 plied localities, I know but of two spots where the plant may be cer- 

 tainly found in Britain. Hence I was much pleased at discovering a 

 new colony of the Lepidium Draba, a few weeks since, and the an- 

 nouncement may perhaps gratify other botanists. What is most re- 

 markable in the matter is, that I feel certain the plant was never there 

 until the present season, as I have doubtless passed the spot it now 

 occupies almost a thousand and one times within the last few years, 

 although this season thirty or forty plants have suddenly sprung up 

 in one particular place. I am almost afraid to indicate the exact 

 locality, lest a file of men from the Worcestershire Natural-History 

 Society should reduce the whole colony to mummies ; but suffice it to 

 say that it grows on the glacis of the embankment of the new road 

 made about seven years since, to the iron bridge over the Teme at 

 Powick, and not near any habitation or ploughed field. It also grows 

 mixed up with the quick of the hedge planted since the road was 

 formed, in company with a rank growth of Malva sylvestris, Sisym-
