1. Lespedeza striata (Thunb.) H. & A. Japan Bushclover. Map 

 1253. This is an introduced species that has spread with remarkable 

 rapidity. So far it is restricted to the southern part of the state, our most 

 northern report being from Howard County. I have been well acquainted 

 with the Clark County State Forest of 2,000 acres since 1909. This species 

 was never sown on the cleared land of the forest or in the neighborhood. 

 It appeared spontaneously in the abandoned fields and soon formed dense 

 stands over acres. The forest is so located that the seed could not have 

 been brought in by water. I have no data as to when I first noticed it there. 

 Its sudden and widespread appearance in Indiana is an interesting problem 

 in distribution. Most of my specimens date from 1911-1920. It is usually 

 found in hard, clayey soil, either moist or dry, in open woodland pastures, 

 and fallow fields and along roadsides and railroads. It has been a boon 

 to the grazing industry in that part of the state since it does not appear 

 until August and September and continues until late in autumn.

2. Lespedeza stipulacea Maxim. Korean Lespedeza. Map 1254. 

 This species was introduced into Indiana as a forage crop about 1925 and 

 has freely escaped to roadsides and open woodland in some of the south- 

 ern counties.
