3. Sporobolus neglectus Nash. Map 231. Infrequent throughout the 

 state. It seems to have much the same habitat as Sporobolus vaginiflorus 

 and is often found with it.

4. Sporobolus cryptandrus (Torr.) Gray. Sand Dropseed. Map 232. 

 Infrequent in dry, sandy soil in the area shown on the map. The specimen 

 from Lawrence County was found in an old stone quarry and the Marion 

 County specimen was found in a waste place on North Meridian Street in 

 Indianapolis. I regard these plants as waifs. The fact that the panicle 

 sometimes remains in the sheath and does not expand has caused a form 

 to be named. I am following Hitchcock, considering the form to be without 

 taxonomic significance.

5. Sporobolus heterolepis Gray. Prairie Dropseed. Map 233. 

 species is infrequent to very local in a few of our northern counties, 

 found in dry or moist prairie habitats.

6. Sporobolus asper (Michx.) Kunth. Map 234. This species is infre- 

 quent throughout the state. It is doubtful that this species is a native. 

 I have noted its advent into the state during the past few years. It now 

 often forms complete stands for rods along railroads, highways, and 

 adjacent fields. It will no doubt, in time, become a weed.

80-216. BRACHYELYTRUM Beauv. 



1. Brachyelytrum erectum (Schreb.) Beauv. Map 235.. Infrequent to 

 frequent in all parts of the state where beech and sugar maple woods or 

 black and white oak woods are found. It prefers dry slopes and, for 

 this reason, it is often very local in some counties. I have botanized Wells
