in abundance in a grass-field tliere, 1868. Hundreds of plants 

 on banks by the Military road ; one plant by the footway 

 within a quarter of a mile of the second milestone from Ply- 

 mouth, and three or four by the tramway near the thu'd mile- 

 stone, beyond Crabtree, 1876. In profusion in some spots 

 near Crabtree, 1878. Cattedown, two or three dozen plants, 

 1873. On a wall-top and in a waste spot by a limestone quarry 

 near Billacombe, 1874, &c. 

 VI. In considerable quantity in a field of grass near Ivyb ridge, 1878. 

 I beheve this to be a very recent introduction, probably with the seeds 

 of clovers and grasses ; but it is spreading with such rapidity that it may 

 become a very troublesome weed. It had never been noticed in the 

 neighbourhood until I found it about the year 1867.

 cross, September, 1866.

 a field at Orcherton, August, 1876.

close to the road to Bull Point ; doubtless sown with the crop, 



June, 1879.
