of rarities than not :—Chenopodium rubrum. Allium vineale. Scirpus

“@. Saxifraga tridactylites and Hieracium umbellatum are not in- 
cluded. Does the compiler of the List think them less common than S. 
granulata and H. cesium? My experience is quite the reverse. I also 
thought Hriophorum vaginatum much more common than Z. latifolinm.” 
On comparing the above remarks with the printed List, it 
appears that about 40 species are liable to expulsion from said 
List, or about one-tenth of the plants supposed common are not 
so. We hope that our enumeration of reputed common plants 
will not share the fate of the Mussulman’s pig; yet we fear that 
if other correspondents cut off so liberal slices, the whole will 
eventually disappear, as the pig did, from the head to the tail. 
Some have requested us to tell our readers how they can avail 
themselves of our List in order to promote the knowledge of the 
range of plants. We submit to such the remarks of our two 
acute correspondents. If such will take the trouble to compare 
the Floras of their respective localities with the enumeration pub- 
lished in our May number, and send us their notes, whether 
these be affirmative or negative, something promotive of this 
branch of the science will be elicited.
