 By Wm. West, F.L.S. 



When investigating cryptogamic plants north of Waterville, 

 Kerry, some years ago (1904), I was so struck one morning with the 

 variety of flowering plants on a wall, that I interrupted my day's 

 journey in order to make notes for publication of those I could 

 readily recognize in the last week of May. These notes got mis- 

 placed until quite recently. It illustrates a very peculiar scattered 

 formation, to wit, the association of such pairs of plants as 

 Veronica Beccabunga (on the top of the wall) and Sclerochloa 

 rig Ida, Cotyledon Umbilicus-Veneris and Senecio aquaticus \ The 

 wall was not far from the sea, where frosts are practically absent,
