In the sori one sometimes finds teleutospores with two distinct germ- 
pores (figs. 14a, 4, and 5). Liro (1906, p. 15) separated from U. Trifolii the 
ectens, 
on +. repens, was in 1909 separated by Lagerheim, as only teleutospores 
occur in the cycle, these appearing in sori which are larger, appear more 
frequently on the petioles and veins, and are longer covered by the 
idermis.
