. FloraLlea<ves cloven into 3, the middle segment long and 

 ointing downwards. Woodward. Stems ascending, mostly 

 >ranched, and from 3 to 5 inches high ; sometimes upright, but 

 little branched, and 10 inches high. Flowers mostly in bunches, 

 but sometimes the lower ones forming a panicle. Caljx 4 or 5 

 cleft, widely conical. Stamens 4 or 5. — Dr. Smith says that 

 the T. alpinum differs from this in having a long tubular calyx, 

 out that otherwise they are much alike. In a specimen of the 

 T. alpinum from Switzerland, the leaves are not only broader 

 than in our linophyllum, but standing more upright they clothe 

 and nearly hide the stem, which is never the case with our plant. 



* Cows eat it. Mr. Atkinson says it is much used as a pickle.
