that time was in flower and held both ui'edo- and teleutospoi'e pustules. 

 Both pustules were mainly hypophylloas, but a few (especially uredo 

 pustules) were epiphyllous. 



The uredo pustules are very brilliantly orange red and circular, but 

 were often so closely aggregated that they ran together. The spores 

 are round or oval, or more or less irregular in shape, and bright orange 

 red (PI. IV, fig. 2). They varied much in size, 28 - 22 x 22 - 17/a. 

 There were no paraphyses. 



The teleutospore pustules are much smaller and appear like minute 

 black dots scattered about irregularly. The spores are very dark brown, 

 generally constricted at the septa, apparently with 2 — 4 pores to each 

 cell, 2 — 5 celled, but usually 4 celled, with a small and inconspicuous 

 mammilla at the free end, looking more like a slight general thickening 

 of the epispore (PL IV, fig. 2). The stalk is long, thin, and inflated at 

 some distance from the attachment to the spore, the inflation containing 

 orange red matter. JSTormal 4 celled spores measured when just wetted 

 68 - 66 X 26/A and a 3 celled spore 54 x 24<fji. 



Of the three species of Phragmidiiim on species of Potentilla de- 

 scribed by De-Toni* only one, namely, Phr. Fragariastri has so few cells 

 to each spore, and the one I have just described is, I think, not identical 

 with it. I have therefore named it Phragmidium nepalense. 



PhBAGMIDIUM OCTOLOCUIiARE, n. s. 

 On Ruhus rosaefolius, Smith. 



The general appeai'ance of the teleutosporic stage of this fungus 

 (the only one I know it in) is very like that of PJir. Bardayi, Dictel,t 

 with somewhat large circular pulverulent hypophyllous pustules. 



The teleutospores are dark brown 7 — 9 celled usually, but mostly 

 8-celled. The surface is distinctly and coarsely tuberculated, and at 

 the free end thei-e is sometimes a minute colourless papilla, but often 

 none. The stalk is long, swells up somewhat in water, is inflated away 

 from the spore, and this lower part of the stalk swells, more than the 

 upper part adjoining the spore (PI. IV, fig. 1). The stalk is not unlike 

 that of Phr. Barolayi. After lying 24 hours in water the gelatinous 

 sheath shrinks upwards towards the spore, leaving a central axis with 

 orange red swellings at the ends. The spore is constricted at each septum 

 to a slight degree. Each cell of the spore is more flattened from above 

 downwards than in the last mentioned species, the vertical depth of 

 each cell being 10/x, against 14/a in Phr. Bardayi. The spores (taking
