REMARKS. There are two species of Puccinia which have been known 
to grow on Anthoxanthum. They are Puccinia Anthoxanthi Fuck, and P. 
borealis Juel. Puccinia Anthoxanthi of Europe is distinguished macroscopi- 
cally from the present species by its naked sorus. From Puccinia borealis of 
America it differs in the form and size of the teleutospores. In P. borealis 
the spore is clavate or subclavate, and smaller (35 —45 X 13 — 20 p ). 
This species approaches in its spore-shape to Puccinia dispersa. But 
the attenuation of the lower cell of the teleutospore in this species is not so 
abrupt as in the latter species. The general form of the spore is rather 
cylindrical than oblong-clavate in our species. Its septum is located in a 
lower position than that of P. dispersa. 
I have not yet seen any specimen of its uredostage, which I believe will 
be found after a careful search. This fact makes the identification still more 
difficult. At any rate, the points of difference from the related species, which 
I have discussed, would justify us in considering this plant as a new species. 
b. Teleutosorus naked.
