Poisoning by O^nanthe crocata. — Mr. W. G. Smith has com- 

 municated an account of a fatal case of poisoning at Staplehurst, 

 Kent. A carter ate some of the roots whilst at work, supposing tiiem 

 to be wild parsneps ; in about another hour he became unconscious 

 and convulsed, and death occurred in half an hour, and before medical 

 aid could be obtained. The man had fed his horse with roots of the 

 same plant, and the animal also expired about two hours after eatino- 

 them. Specimens of the plant were sent up to Mr. Smith for identifica- 

 tion. It is worth notice that he observed the juice to be yellow. 



POTAMOGBTON ZOSTERIFOLIUS, Schmn., AND P. ACUTIFOLIUS, 



L. — Any botanist who knows of existing localities for either of these 

 species within a day's excursion of London, will greatly oblige the 

 editors by communicating them to this Journal. 



A Note tor the ' Middlesex Flora.' — Juncus compressus, Jacq., 

 Poa compressa, L., Melilotus leucantka, Koch, Reseda Luteola, L., Hg- 

 pericum hirsutum, L., Erytlircea Centaurium, Pers. : six species more or 

 less local in Middlesex, are at present in flower at Shepherd's Bush. 

 They grow in two adjoining and now abandoned brickfields, which 

 occupy part of the angle which the Uxbridge Road makes with Wood 

 Lane, just to the north of St. Stephen's Church. The survival and 

 concurrence of these six plants at the very edge of the bricks and mor- 

 tar of advancing London is worth record. In one or two years their 

 station must be built over. One of the chief interests of a metropolitan 

 Flora is to supply data which mark the gradual extension of a great 

 city. — J. L. Warren. 



PoTTiA PALLIDA, Lhidb., A NEW BRITISH Moss. — Mr. Holmes, of 

 Plymouth, has found near that place a species of FoUia, which he sent 

 me under the name of P. Wilsoni, but which is at once distinguishable 

 from that species by its smooth calyptra, though resembling it in havino- 

 octofarious leaves and an excurrent nerve. I have no doubt it is P. pal- 

 lida, Lindberg, hitherto only found on the coast of Spain, and differin"-
