1 All of the teliosporic material used in this set of experiments was obtained by inoculating Pentstemon 
laevigatus with the teliospores of Puccinia ellisiana in the spring of 1913. The resulting asciospores from the 
Pentstemon leaves were then sown on A ndropogon virgmicus. All was done under control conditions in 
the greenhouse. The rust thus obtained on A ndropogon virginicus is here called “ Fuceinia ellisiana from 
Pentstemon/' although it does not differ materially from the ordinary Puccinia andropogonis whose serial 
host is normally Pentstemon. 
2 The teliosporic material used in these experiments was on Andropogon virginicus and came from two 
sources: (1) Pedigreed greenhouse material inoculated and grown under control conditions at the green¬ 
houses of the Department of Agriculture at Washington, D. C.: and (2) pedigreed material grown under 
observation for 3 years at Queen, Va.
