Smilax Bona-nox L. 



Gibson and Vigo Counties. All of my specimens are from low woods on the 

 flood plains of streams. 



Ont. to Minn., southw. to Tenn. and Mo. 



4. Smilax glauca Walt. var. genuina Blake. Sawbrier. Map 670. Our 

 plant is the typical form of the species, distinguished by Blake (Rhodora 

 20: 78-80. 1918) as var. genuina. Infrequent to common in the hilly 

 counties of the southern part of the state and extending as far northward 

 as Marion and Putnam Counties. It is found in open woodland and in fal- 

 low and abandoned fields. When it becomes established in cultivated 

 ground, it is difficult to eradicate on account of its deep, tuberous rhizomes 

 which, when broken, send up new stems. 



Va. to s. 111., southw. to Fla. and Tex. 



5. Smilax Bona-nox L. Fringed Greenbrier. Map 671. I have seen 

 specimens from only the counties indicated on the map and I think 

 Andrews' report from Monroe County can safely be transferred to the 

 next species. So far it has been found only on the high hills near the Ohio 

 River where it is usually associated with the next species. 



Va., s. Ind. to Kans., southw. to Fla. and Tex. 



6. Smilax rotundifdlia L. Roundleaf Greenbrier. Map 672. This species 

 is rare to infrequent in the northern counties, rare or absent in many of 

 the counties in the Tipton Till Plain, becoming frequent to common in the 

 southern counties. It is found in dry soil in woods, clearings, and aban- 

 doned fields where it often forms impenetrable thickets. It forms long 

 vines, and, on account of its many prickles, it is an objectionable plant. 



N. S. to Iowa, southw. to Ga. and Tex. 



7. Smilax hispida Muhl. Hispid Greenbrier. Map 673. An infrequent 

 species throughout the state. It prefers a moist, rich soil. 



Conn., Ont. to Minn., southw. to Va., Tenn., and Tex.
