In this second instalment of a descriptive list of the Uredinece of 

 Simla (commenced in this Journal, Vol. LVI, Pt. II, No. 3, 1887), I 

 propose giving the characters of all the Puccinia with which I am 

 acquainted, dividing them artificially into two classes, (a) those occur- 

 ring on hosts other than the grasses (and sedges), and (h) those on the 

 grasses and sedges. The former list is, I believe, fairly complete, but 

 doubtless many additions will bo made in future to the latter. These 

 fungi on grasses are often so inconspicuous that they readily escape even 

 trained observation. 



I had hoped to have completed the list of ^cidial forms by de- 

 scribing those on the Ooniferce, one on Jasminum grandiflorum, L., and 

 another on Qeranium, sp., before proceeding to the teleutosporic forms ; 

 but, as I must delay the publication of a description of the former until 

 I shall have filled up certain gaps in my notes of them by further 

 observation, I think it better to proceed with the other forms rather 

 than to delay the whole series, more especially as my recent absence 

 from India for a year has already interfered with work too long. 



In the list now given, sixteen species are described in the first list, 

 of which three, I believe, are new ; and nine in the second list, of which 

 four are perhaps new. In the case of those species which occur on grasses, 

 it is extremely difficult to decide which should be considered new, and 

 which should not. Any classification of them must remain extremely im- 

 perfect until their life-histories are known. Of the new species in the first 

 list, that which I have named Puccinia Uoscb is interesting in giving rise 

 to a powerful odour, and in possessing an all-pervading mycelium in the 

 shoots attacked. P. Qalii, Pers., exhibits an instance of very unnsally 

 long retained power of germination in the uredospores. P. Buhice 

 appears to be a complete autoecious Uredine in which secidial fructifica- 

 tion has dropped out.* 



I have arranged the species in List I. under group headings Lepto- 

 puceinia, Micropuccinia, &o., as is done by Winter in his workf ; but I
