220 A. Barclay — Additional Ui^edineae from Simla. [No. 3, 



presumably germinate at once. They measure when just wetted 52 — 45 

 X 24 - 22/*. 



This is possibly Puccinia pulvinata, though the measurements given 

 by De-Toni are greater than mine (G8 — 51 x 38 — 35/a). 



PHRAGMIDIUM. 



Pheagmidium Laceianum, n, s. 



On Fotentilla argyrophylla, Wall. 

 I first received specimens of this plant harbouring a parasite from 

 Mr. Lace, who gathered them in Bashahr. Subsequently I found 

 specimens myself at Narkanda, and Dr. J. Murray procured specimens 

 at Sarhan in Kulu. 



The uredo pustules are hypophyllous, brilliantly orange red, discrete, 

 but often so numerous as to give an appearance of coalescence. Each 

 individual pustule is circular and minute. The spores are round to 

 oval or pyriform, bright orange red, spiny, and measuring when just 

 wetted 24 - 20 X 18 - 16/A (PI. IV, fig. 3). 



The teleutospore pustules are also hypophyllous, black, circular, 

 discrete. The spores are deep brown, on stalks which narrow gradually 

 away from the spore. They are mostly five-celled ; but some are four 

 and some six-celled. The surface is apparently smooth, the free end 

 rounded and slightly thickened, with usually a minute colourless papilla. 

 When just wetted they measure 132 — 94 x 50 — 41yu.. I could not 

 detect any germ pores ; and they would not germinate immediately 

 after ripening. 



The specimens sent by Mr. Lace, and those collected by myself were 

 on the red flowered variety, whilst those collected by Dr. Murray were 

 on the yellow flowered variety, This fact may tend to confirm the view 

 taken in Hooker's Flora of British India that these two are varieties of 

 the same species. 



This fungus is, I think, distinct from any of the three noted in 

 Saccardo's Sylloge as inhabiting species of Fotentilla. It is not Phr, 

 Fragariastri, D. C, which has warty teleutospores, 75 — 45/x long and 

 3 — 5 celled. It is not Phr. Potentillae, Pers. which has smooth teleuto- 

 spores, 90 X 26//.^ and 3 — 7 celled. And it is not Phr. Tormentillae, Puck. 

 which has spores of ten bent, 115 x 28/a, 3 — 8 celled, and light brown. 



Phragmidium nbpalense, n. s. 

 On PotentiUa nepalensis, Hook. 

 I found this host in September attacked with a Phragmidiurii at 

 Mattiana, some miles towards the interior from Simla. The host at
