108 A.Barclay — A Descriptive List of the Vredmex [No. 2, 



The uredospores are pale brown echinulate bodies, oval and measur- 

 ing 23 X 18/x on an average. The spores germinated in water in the 

 usual way (fig. 9, PI. I). I have occasionally seen a globular expansion 

 at the end of the germ tube, as shown in the figure ; but this is never 

 separated off by a septum. 



The teleutospores are very deciduous, falling off with only a frag- 

 ment of stalk adhering. They are dark brown and very variable in 

 size and shape, somewhat constricted at the septum, with a smooth 

 surface, and slightly thickened at the apex. A clear nucleolar space is 

 seen in each cell (fig. 9, PL I). The fresh spores measured from 25 

 to 36/x in total length, by 11 to 13/x at the septum. The septum divides 

 the spore into two almost equal halves. The upper cell is often much 

 broader than the lower, and is more or less globular. The apical thicken- 

 ing is about 4/x in depth, the cell wall elsewhere being about 2)U, in 

 thickness. The spores do not germinate immediately after ripening. 



5. PucciNiA Gentianae, (Strauss). 

 On Gentiana Kurroo, Royle. 



I found two plants of this host at the end of December largely 

 attacked with a Puccinia, on a hill some miles from Simla to the south 

 (near Solon) ; but have never seen it again. The plants I found were 

 withered. The under surfaces of the leaves bore numerous black cir- 

 cular isolated pustules. On examining the spores from these they were 

 found to consist of teleutospores with a few uredospores. The spores 

 are readily detached from their beds, coming off with a fragment of 

 stalk usually adhering. 



The uredospores are oval, pale brown bodies, spiny, measuring 26 x 

 22fji after lying 24 hours in water. 



The teleutospores are plump and rounded at both ends, and slightly 

 if at all constricted at the septum. The epispore is very finely tubercu- 

 lated over both cells, and is uniformly thick, with the exception of a very 

 shallow mamillated thickening at the free end. Each cell of the spore 

 exhibits a clear nucleolar space or body. After lying 24 hours in water 

 these spores measured from 38 to 40/x in length by 25 to 26 in breadth. 

 They are very uniform in size. They do not germinate immediately 

 after ripening. Occasionally a single celled teleutospore may be seen. 



Be7narhs. — This is most probably P. Gentianae (Strauss) as the 

 characters of both uredo and teleutospore agree ; but I have not seen 

 any Aecidium. The locality, however, in which I found the fungus is 

 not familiar to me : I have only once visited it in winter.
