at Erode in the Madras Presidency, which is undoubtedly the same 

 as that on Sorghum. As neither of these fungi (on Sorghum and 

 Pennisetum') are Himalayan I shall not describe them in detail here ; but 

 in order to enforce my argument that the fungus on Zea is P. Sorghi, 

 whilst that on Sorghutn and Pennisetum is a different species, which I 

 shall call Puccinia Peiiniseti, I subjoin in tabular form their salient 

 characters.

Puccinia Ellisii, De-Toni ? 



On Angelica glauca, Edgw. 



This plant was found by Dr. G. Watt afc Fagoo in August, bearing 

 uredo- and teleutospore pustules, both minute, discrete, and hypophyl- 

 lous ; but whilst the former are pale yellow, the latter are dark brown 

 to black. Both kinds of pustule occurred together on the same leaf. 



The uredospores are round to oval, very pale yellow, very spiny, and 

 when just wetted 30 - 24 X 25 - 20/a. (PI. IV, fig. 9). 



The teleutospores are deep brown, rounded at both ends, slightly 

 constricted at the septum, coming off with little or no stalk adhering, 

 not thickened as a rule at the free end, and tuberculated over both 

 cells (PI. IV, fig. 9). They are sometimes irregular in shape. They 

 measured when just wetted 38 — 22 x 22/x. 



This is possibly Puce. Ellisii, though both the uredo- and teleuto- 

 spores of this last mentioned species are larger, the former measuring 

 35 - 30 X 30 - 24, and the latter 40 - 35 X 25 - 20/x. It is certainly 

 not Puce. Angelicae, Schum. which shows a tendency to erupt along the 

 nerves, among other differing characters. 



Puccinia Oastagnei, Thiim ? 



On Apium graveolens, Linn. 



I have hitherto confused a fungus on this host with Puce. Pirn' 

 pinellae, Strauss ; but it is certainly distinct. 



The uredospores are very pale brown, covered sparsely with spines, 

 and with three germ pores, each covered with a hyaline semilunar
