104 A. Bai'clay — A Descriptive List of the Uredinea? [No. 2, 



Cooke, considered both species identical (see Indian Forester, 

 Vol. Ill, 1877-78) and named it Periderminm orientate, C. but as 1 thiuk 

 there is no doubt whatever they are quite distinct I have re-named both 

 species. 



In a paper describing a Chrysomyxa (G. Himalense) which is ex- 

 ceedingly common in Simla on Rhododendron arboreum, Sin., I have 

 drawn attention to a possible connection between the Aecidium on 

 P. excelsa and this Chrysomyxa* and have given reasons why a connec- 

 tion with the Aecidium on P. longifolia is not probable. The occurrence 

 of a double crop of aecidia on P. longifolia, of which I did not know 

 when I wrote tbe paper referred to above, renders it, however, still more 

 difficult to conjecture the life history of this parasite. 



N. B. — In order to complete this list I would here draw attention 

 to three other Aecidia on other species of the Goniferae, namely, two 

 distinct species on the needles of Picea Morinda and one on the Deodar. 

 These I had already fully described in this Journal before I commenced 

 a systematic review of all the Uredineae of this region. For one of 

 those on Picea Morinda {Abies Smithiana) described in Vol. LV, Pt. II, 

 No. 1, 1886, I propose to retain the name 



3. Aecidium Thomsoni, Berkeley. 



although there is some doubt as to the identity of that species with the 

 species in this region ; and for the other, described in the same volume, 

 Pt. 2, No. 2, I propose the name 



4. Aecidium Piceae, nov. sp. 



The species I have described on the Deodar, Volume LV, Pt. II, 

 No. 2, 1886, I now propose naming 



5. Aec. Cedri, nov. sp. 

 6. Aecidium Plectranthi, nov. sp. 



On Plectranthus Coetsa, Ham. 



An inconspicuous and rare Aecidium was found first on the 4th 

 July, and then shortly aiterwards on a very few bushes in the same 

 locality. The aecidial patches are small, and a single leaf sometimes 

 contained several of them ; but usually only one or two. On the upper 

 surface of patches spermogonia could be seen with a field lens, while 

 the under surface bore the peridia. These are short cups open stellately,
