PUCCINIA CAUDATA, n. S. 

 On Stellaria paniculata, Edgw. 



Dr. G-. Watt collected this plant in JSTarkanda, bearing a Paccinia. 

 The teleutospore beds are dark brown, well raised with a circinate 

 tendency, and hypophyllous, with paled patches on the upper leaf surface. 

 The spores are very adherent, more or less spindle-shaped, pale brown, 

 well constricted at the septum, usually much thickened at the apex, 

 with a long piece of adherent stalk (often twice, or a little more, than 

 the whole length of the spore) and measuring 37 — 28 x 16 — 13/^ 

 (PI. V, fig. 17.). 



This is evidently not P. Arenariae, Schum. and I have regarded ifc 

 as a new species. 



PUCGINIA CRASSA, n. S. 

 On Pini'pinella Orifjithiana, Boiss. 



This was gathered by Mr. Lace in Ziarat in Afghanistan at 8,000 feet. 

 The teleutospore pustules are dark brown and hypophyllous. Tlie spores 

 are brown, almost rounded at both ends, but diminishing somewhat 

 towards the stalk, of which a small fragment remains adherent. They 

 are slightly constricted at the septum, and slightly thickened at the 

 apex (PI. V, &g. 16). When just moistened the spores measure 50 — 41 

 X 24 — 22/x, The epispore has shallow tubercles over both cells. They 

 would not germinate. 



This fangus is quite distinct from P. Pimpinellae, Strauss which 

 is one of the most common of the Uredineae in Simla. Neither are the 

 spores like any of the otlier species inhabiting Pimpinella described by 

 De-Toni* (except perhaps P. Pimpinella,. ^t var. Eryngii, D. C ) It is 

 I think a new species. 



PucciNiA PULVINATA Rabenh. ? 

 On Echinops niveus, Wall. 



A Puccluia on this host was gathered for me by Dr. G. Watt in 

 Simla. The leaves had numerous minute well raised black pustules 

 all epiphyllous. The spores are readily detached from their beds. The 

 plant was in full flower inclining to seed. The spores come off some- 

 times with a long piece of stalk attaclied, sometimes with a short. The 

 spore surface is studded with shallow tubercles. They are brown 

 slightly constricted at the septum, mostly rounded at both ends, the 

 free end slightly thickened. Most spores were found empty, so they
