2 'Q\lLYA\ Adventitious Vegetation of St. Anne s-on-the-Sea. 



discharge the ballast which they had taken in in foreign 

 lands. And yet its adventitious vegetation is somewhat 

 remarkable. Excluding the escapes of cultivation — 

 which are numerous — I confine the following remarks to 

 the four aliens which are the special subject of this paper. 



Its sandhills and waste places yield an abundant 

 supply of one of the North American evening primroses, 

 CEnotJiera biennis, Linn. How long this plant has been 

 growing in the district is not known, but it has been 

 established in other parts of the Lancashire coast for the 

 last seventy or eighty years. Whenever the land is dis- 

 turbed, or the sand removed to form new roads, this plant 

 is one of the earliest to grow upon it, and, although its 

 conspicuous flowers make it an easy prey for constant 

 plucking, it survives these depredations and continues to 

 spread more and more. 



The roadsides and sandhills furnish a home for large 

 numbers of another colonist, the Sisyvibrinin pannonicum 

 of Jacquin, belonging to central and eastern Europe, and 

 from western Asia to India. It is an annual plant, 

 growing from two to three feet in height, and fruiting 

 freely, so that it is likely to become more disseminated 

 than at present. Compared with my last year's observa- 

 tion of the plant, it occupies a larger area this year, and 

 it is extending inland. Mr. J. A. Wheldon, of Walton, 

 tells me that it occurs about Preston, and that he has 

 seen it this summer in the neighbourhood of the corn- 

 elevators at Fleetwood. Its general habit may be seen 

 from the living and dead plants now shown to the 

 members, which were collected a day or two ago. 



I have now to report the occurrence of a third alien 

 which, though not occupying anything like the extent of 

 ground possessed by the GEnothera and SisymbriutJi, has 

 ever)- appearance of having been established for some
