seeded. In 1933 I found it in Steuben County and in 1934 1 found it in 

 La Porte County. This is a pernicious weed.

3041. HESPERIS [Tourn.] L. 



1. Hesperis matronalis L. Dames Rocket. Map 1054. This species has 

 long been used and is still commonly planted as an ornamental plant. It 

 was never reported, however, by our early authors. The first report is that 

 of Grimes in 1910. Nieuwland, in 1915, reported it as escaped along the 

 bank of the St. Joseph River in St. Joseph County. In 1921 I found it to 

 be frequent in a wooded ravine about a half mile west of Aurora in Dear- 

 born County. In 1933 I found it to be a common and abundant weed along 

 the roadside and in an adjacent, fallow field just west of Aurora. Naomi 

 Mullendore has collected it in Johnson County.

3055. CONRINGIA [Heist.] Adans. 



1. Conringia orientalis (L.) Dumort. Hares-ear Mustard. Map 

 1055. All of my specimens except one are from railroad ballast. It has 

 been reported from seven counties and all who mention its habitat except 

 one say that it was found along railroads. Apparently this species is slow 

 to establish itself in fields and may not become a serious pest.
