THE BASIDIA OF PUCCINIA MALVACEARUM 539 



end-conidia (Fig. 217). Usually these conidia were four in number 

 (C and D), but sometimes they were three (A and B) and sometimes 

 only one (A). These end-conidia are not violently discharged so 

 that it is not astonishing to find that the curvature of the basidium, 

 such as exists in basidia which are developed in air and which 

 violently expel their spores, is not typically formed.
