The fungus is none the less interesting when compared with Puccinia 

 lobata, B. & C, collected by Wright on Sida lepiota in Texas. The 

 spots are of the same color as in the last-named species, but the 

 spores are decidedly smaller in P. lobata, and more obtuse. What we 

 have called P. Malvacearum, var. Ilalvastri, is exactly intermediate 

 between P. llalvacearum, on the one hand, and P. lobata, on the other, 

 agreeing in the size of the spores with the former and in color with 

 those of the latter. The spores are not so acute as in P. Malvacearum, 

 nor so obtuse as in P. lobata. The connection between P. Malvacea- 

 rum and P. lobata, which the form collected by Mr. Cleveland seems 

 to indicate, is, to say the least, worth consideration.
