ON SPERGULA ARYtiNSIS. 



Aberdeenshire, but although S. satira was extremely abundant in 

 most places, S. vulgaris seemed entirely absent ; and'l am informed 

 by Prof. J. W. H. Trail that during his botanical excursions in 

 Aberdeenshire and the surrounding counties he carefully examined 

 the Spergulas he met with, but failed to find S. vulgaris. This 

 negative evidence, coupled with the foregoing facts, goes to prove 

 that although S. vulgaris may be common in some places, it 

 is certainly (m Britain) much the rarer of the two forms. 



To return however, to the specimens in the Kew Herbarium 

 and at the British Museum. By far the greater number are 

 labelled with the aggregate name arvmm, but I have carefully 

 examined them and determined to which of the two forms the 

 different specimens belong. The results show that although 

 8. satira is by far the prevailing plant, as far as Britain is 

 concerned, the very opposite holds good when the total distribution
