0b$. This is an introduced and pernicious weed. The plant has n resinous 

 od r ; ami is believed to produce troublesome sores on horses and horned cattle,— 

 especially those which have white feet and noses— the skin o\' such being more 

 lender, or irritable. Tin; dew which collects on the plant appears to become 

 acrid ; as I have ten the backs of white cows covered with s »res, wherever '.he 

 bushy ends of their tails had been applied, after draggling through the St. John's

 effect in some complaints of the stomach and bowels.
