and firmly adherent to their beds, breaking off with a long piece of the 

 stalk adhering (70 /t long in one case measured). Each cell has a clearly 

 defined nuclear space (Fig. 8 a, h, PI. XII). The free end of the spore is 

 considerably thickened and pointed. The spore is elongated, spindle-shap- 

 ed, well constructed at the septum, and narrowing at both ends (Fig. 8, 

 PI. XIII.) The whole spore measures when moist from 61 — ^65 in 

 length, the upper coll fi-om 26—36 /x. in length by 16 /x in greatest breadth, 

 and the lower from 25 — Sljit in length by 14 in greatest breadth. 

 The septum measures 11 — 12 /«, in breadth and the thickening at the 

 free end 6—11 /x in depth. After lying 24 hours in water some spores 

 germinated throwing out short promycelia with colourless contents. The 

 upper promycelium emerges from a point to one side of the apex, and the 

 lower from a point near the septum. They did not go on to the forma- 

 tion of sporidia. 



Bemarlts. — These characters do not agree with those given by 

 Winter,* for P. SaxifragcB, Schlechtd., or P. AdocecB, D. C. In the 

 former case, the teleutospore pustules are aggregated together in irregu- 

 lar and variously coloured areas (seldom isolated), and the spores are 

 deciduous and much smaller than those of the Simla species. The teleuto- 

 spore beds of P. AdoxcB likewise coalesce, and the spores are deciduous 

 and considerably smaller (30 — 45 /x long). In one point, however, there 

 is a resemblance : in both the free end has often a pale lengthened 

 thickening or projection. But, as P. Adoxce is an autcecious Enpuccinia, 

 I am inclined to regard the Simla species provisionally as distinct.

on Circwa alpina, Linn. 

 This fungus is met with at higher elevations than Simla, namely, 

 about 9000 feet. I found it occurring plentifully in the forests near 

 the " Ohor " mountain. Each attacked leaf usually displays numerous 

 dark brown pustules on its lower surface (50 and more) varying in size 

 from a minute point to 1 to 2 m. m. in diameter, and each surrounded by 

 a zone of discolouration. Examined with a lens each pustule is seen to 

 consist of numerous minute hemispherical beds aggregated together. 

 The teleutospores are firmly adherent and when scraped off become 

 detached with a long piece of stalk adherent and usually come off in 

 masses. The spores are very small, brown, elongated, constricted at the 

 septum, much thickened at the free end with the lower cell narrowing 

 towards the stalk (Fig. 11, PI. XIV). The free end is more or less pointed. 

 Herbarium specimens of spores when moistened measure from 30 to 32 /x 

 in total length (the upper and lower cells being usually equal in length)
