these slopes.

AMARYLLIDACEAE 
Agave virginica L. American aloe was 
seen on stony slopes at Allen Lake and 
Cave Creek, and on loess slopes at Fults, 
Sampson, and Phegley. It was observed 
also on rock ledges at South Prairie du 
Rocher and Stotz. The mature plants 
seem to flower every year. In thin soil 
on rock, the plants have short vertical 
stems and leaf-bases that vary in length 
with the depth of the soil. The fleshy roots 
radiate horizontally over the rock surface. 
In places, chiefly on rock ledges, the ro- 
settes form fair-sized patches.
