SHORT NOTES. 



AsTEU Novi-Belgii, L. — This plant has become established in 

 three localities in Surrey, in the neig-hbourhood of London, and it is 

 probable that many other localities exist for it under like circumstances. 

 Two of the places where I have seen the plant are on the banks of the 

 Thames ; one about half a mile below Richmond railway bridge, where 

 Mr. Baker has observed it in previous years, and the other about half 

 a mile above Hammersmith bridge, where Mr. Britten has noticed it 

 for several years. It also occurs in Putney parish, by a ditch in some 

 waste ground close to Bayeley bridge, near Wimbledon Common. The 

 plant has been seen by Prof. Asa Gray, and the name of Aster Novi- 

 Belgii, L., has been approved by him. Several species of Aster will 

 probably be found to establish themselves in Britain, and it is worth 

 while to record them as they appear. This is an American plant, and in 

 this respect differs* from Aster salignns, Willd., which is European, 

 and has occurred in Cambridgeshire and other places. — W. P. Hiekn. 



CoTULA CORONOPIFOLIA, L. — This inconspicuous Composite weed 

 has occurred in some plenty this autumn in a brickfield in Green 

 Lanes, Highbury New Park, London, where it was found by Mr. P. 

 Gray, to whom we are indebted for specimens. The plant occurs in 

 East Eriesland, Oldenburg, and near Hamburg, in places near the 

 coast of the Ger.man Ocean ; and also in Spain. Out of Europe it has 

 an extensive range, being found in Brazil and Chili, at the Cape of 

 Good Hope, in New Zealand and Van Diemen's Land, and elsewhere. 

 C. aurea, L., a native of S. Europe and the East, occurred a year or 

 two ago in cornfields at Mitcham, where it was associated with many 

 other exotics, obviously introduced with foreign grain. 



Erica vagams, L. — We have been shown specimens of this, said to 

 have been gathered last August, in a perfectly wild state, in North 

 Wales, between Dolgelly and Machynlleth. This species has been re- 

 corded from Glamorgan, and many other counties^ besides Cornwall, 



* Professor Babington, following De Candolle, considers A . salignus, Willd., 

 exclusively European (Journ. of Bot. Vol. V. 368) ; but it seems to be scarcely 

 separable from the American plants called A. longifolius, Lam., A. simplej; 

 Willd., and A. puniceus, L. (see Journ. of Bot. Vol. VII. pp. 139, 140). Pro- 

 fessor Asa Gray, indeed, quotes (Man. Bot. Northern U.S. p. 234) A.sali- 

 cifoUus, Sclioller(a synonym oi A. salignua) under A. longifolius. — [Editoes
