A Remarkable Case of Fasciation in Oenothera 



Biennis. 



Paul Weatherwax 



Near the middle of last July a student brought into one of the laboratories 

 of the Botany Department of Indiana University a specimen of Oenothera 

 biennis L., the stem of which was fasciated to such a remarkable degree that 

 it is considered worthy of mention here. 



The height of the plant was about 1.5 meters, which is probably a little 

 more than the average for the plant in the vicinity of Bloomington; but the 

 width and thickness of the stem were very much out of proportion to the 

 height and to each other. Near the ground it was 5 em. wade and 2 cm.
