Biology. — The jecidiospore mycelium is perennial, and the affected 

 plants are altered in habit, being paler in colour and more elongated 

 in their stems and petioles. The mycelium of the uredospores and 

 teleutospores is purely local. 



Puccinia primulae. (D. C.) 



JEcidiospores — Pseudoperidia hypophyllous, in roundish clusters, 

 shortly cylindrical, with whitish torn edges. Spores sub- 

 globose, finely echinulate, orange-yellow, 17-23 X 12-18/x. 



Uredospores — Sori small, hypogenous, brown or yellowish, rounded, 

 pulverulent. Spores ovoid, brown, echinulate, 20-23 X 

 15-18/X. 



Teleutospores — Sori hypogenous, greyish brown. Spores ovate or 

 oblong, slightly constricted, apex thickened, smooth, brown, 

 22-30 X 15-17/^. Pedicels short, deciduous.
