126 Rhodora [JUNE 
Cuscuta arvensis, Beyrich. Oxford and Southbury. Probably in- 
troduced with grass-seed. 
Pentstemon laevigatus, Solander. This appears to be frequently in- 
troduced with grass-seed, when it persists until the original plants die, 
but does not seem to spread. Of four stations which I have known, 
three are extinct. At the fourth in Southbury it still grows.
