islands of Fiinen and Laaland. The outer flowers were "brown- 

 violet, the inner yellow." 



During the month of June, 1910, it was the writer's privilege 

 to make frequent observations upon both T. porrifolius and 

 T. pratensis along the right-of-way of the C. M. & St. P. R. R. 

 at Elgin, 111. For a distance of several hundred feet the two 

 species were abundant, the former occurring in the northern half 

 of the tract and the latter in the southern half. Where the 

 two kinds met, there were found not only plants of each species' 

 but also some thirty or more plants quite distinct. In size, 

 the last plants more nearly resembled T. porrifolius, which in 

 that vicinity was considerably the more robust plant. The 

 flowers possessed, to a remarkable extent, the color pattern ob- 

 served by Lange in the hybrids of Fiinen and Laaland; the 

 outer flowers of each head being a reddish "brown-violet" and 

 the inner a yellow color. The involucral bracts were mostly 

 equal in length to the ray flowers. A remarkable uniformity 

 prevailed in the flower-colorations, size of the mature plants, 

 and proportionate length of the bracts. Individual plants were 

 examined from time to time and in no case were they found to 

 bear pure yellow or pure purple heads. However ramose the 

 plant, its several branches produced heads with uniformly the 

 outer flowers reddish brown-violet and the inner flowers yellows 



It thus becomes obvious that these plants were nothing more 

 or less than hybrids between the two species that abounded in 

 either direction. It is the more obvious because they were found 

 growing only in a small restricted area of about three square rods 

 where the two pure stocks met.
