 REMARKS:— Comparing this witli other species of Phragmidlum already 

 known to grow on Horn, I am disposed to regard it as a new species. 



Ba:s"Di (1) makes the >tatement that Ph. subcortidwii (Schrank.) Wint fails to 

 attack Mosa rugona even when artificially infected. Rosa arkansana, R. hlunda, 

 R. setigera, R. foliosa, R. iiilida, R. Engelmumii, R. gymnocarpa, R pisocarpa, R. 

 Woodisii, R rubiginosa, R. ruhrifolid, and R. lucida in the Botanical gr.rdcn of onr 

 College have proved to be perfectly immune to IJ^ragnüdiuim, while Ro-'<a rugosa, 

 planted near by, is seriously infected by two different species of Pliragji.idiuvi, boili 

 of which are peculiar to our c.iuntry ; namely Ph. Rosae-rugosae n. sp and Ph. 

 yczojuse n. sp. Macroscopically the present species is allied to Ph. .^ubcorficiuni 

 (Schrank.) Wint. with regard to the form of its cseomata and other st:ig<As But 

 in the following points they are at variance.
