5. Silene dichotoma Ehrh. Forked Catchfly. Map 919. I have 

 found this species in two places, and in each it seems to be well estab- 

 lished. In 1915, I found it to be common along the roadside 4 miles north 

 of Vevay in Switzerland County. In 1931 I found it to be a common weed 

 in a very sandy alfalfa field about 4 miles southeast of Mongo in Lagrange 

 County. I revisited the place in 1932 and I found the field in corn but the 

 plant was frequent along the sandy roadside which bordered the field; 

 and I found it still persisting in 1937. I believe it is well established in both 

 places and it is entitled to membership in our flora. It has also been col- 

 lected in Fountain, Fulton, and Lawrence Counties.

6. Silene antirrhina L. Sleepy Catchfly. Map 920. This species is 

 variable. It prefers a very sandy habitat and is frequent in railroad bal- 

 last throughout the state. It is less frequent in fallow and cultivated fields, 

 pastures, and waste places and along roadsides. Our manuals give this 

 species as a native of the United States. I do not believe, however, that it 

 was a native of Indiana. Our earliest authors either do not list it or give it 

 as a plant of waste places. M'Murtrie, who published a flora of Louisville 

 in 1819, does not list it, nor does Riddell, who published his "Flora of the 

 Western States" in 1835. Short, Peter & Griswold published a catalogue of 

 the plants of Kentucky in 1833, and they do not list it. Neither do they 

 list it in any of their four supplements, the last published in 1840. Lapham 

 lists it from Illinois in his flora published in 1857. Dr. Clapp records that 

 he found it in 1835 east of Corydon and in the "barrens." Young, in his 

 catalogue of the plants of Jefferson County published in 1871, does not list 

 it. J. M. Coulter, however, reports it in his catalogue published four years 

 later. Schneck, who published a flora of the Lower Wabash Valley in 1876, 

 says : "In poor grounds among cereals, common." Bradner, Phinney, and 

 Van Gorder did not report it in their floras. Apparently it has become a 

 frequent weed during the past 50 years. I believe it has been introduced 

 mostly in grass and grain seed and by railroads. 



A form with the internodes lacking the glutinous band is known as f.
