Urbdo Ichnooarpi, n. s. 

 On Ichnocarpus frutescens, Br. 



This fungus was also collected by Dr. Watt in the same neighbour- 

 hood, and at the same time. The leaves bore a few scattered isolated, 

 bright orange red pustules on the under leaf surface. The spores were 

 readily scraped off. They are bright orange red, oval, studded with 

 large coarse warts or spines, and measure when just wetted 24 — 20 x 

 16 — 2lfi. Even in empty spores I could not detect any germ pores. 

 Among the scraped off uredospores I saw some immature single celled 

 stalked spores which I imagine are teleutospores ( Uromyces) ; but they 

 were too immature to allow of decision. They were colourless at this 

 early stage. 



An Aecidium Apocyni, Schwein. is known to occur in Carolina, 

 Kansas, and Illinois ; but it is impossible as yet to say whether it is in 

 any way related to the Himalayan fungus : probably it is not, 



Uredo Ipomabab, n. s. 

 On Ipomaea hederacea, Jacq. 

 This plant was collected by Dr. Watt near Sairi in September with 

 numerous, white, irregularly shaped covered pustules on the under leaf 

 surface. On examining the pustules they were found to contain an 

 abundance of white powdery spores. The spores are colourless, round 

 or squarish, apparently quite smooth on the surface, and measuring when 

 just wetted 20 — 17 x 16 — 14/*. Although I have placed this fungus 

 here among Uredo forms I should note that it looks much like the 

 Aecidium of a Phragmidium, differing only in not being coloured. 



Uredo Pileab, n. s. 

 On Filea trinervia, Wt. 



I found a few of these plants in the woods at Mashobra early in 

 October, attacked by a Uredo. The pustules were minute, pale yellow, 

 and scattered on the under leaf surface. The spores are oval, very pale 

 yellow, studded with prominent spines, and measured when just wetted 

 25 — 20 X 20 — 14/x. I could find no trace of any teleutospore form up 

 to the middle of October. 



Uredo Ehretiae, n. s. 

 On Ehretia serrata, Eioxb, 



This fungus was collected by Mr. J. S. Gramble on the banks of the 

 Tons river near Chakrata. The leaves are attacked by a Urediaous
