THE UREDINALES FOUND UPON THE ONAGRACEAE

the somewhat different appearance of this rust in the micro- and lepto- 
form, may have led to the supposition that an Uredo occurred upon 
Circaea.

Holway places with this species Puccinia annulata Ell. & Ev., 
both of which occur upon Chamaenerion angustifoUum (L.) Schur. 
{Epilohium angustifoUum L.). Puccinia annulata was described as 
possessing smaller teliospores, yet the two species no doubt go to- 
gether, Puccinia annulata being but an American variation of the 
European Puccinia gigantea. 
This species is not greatly different from Puccinia Circaeae, and 
appears to be correlated with Puccinia Jussiaeae. Only a very few 
collections are at hand, however.

This species, as far as is known, has only been collected once, at 
Amecameca, Mexico. Sydow, /. c, suggests that this species is much 
like Puccinia Jussiaeae from South America. It may, however, 
quite probably be a correlated short-cycled form. An examination 
of the original material discloses no very obvious difference from 
Puccinia gigantea. The host listed is Fuchsia thymifolia.

This species, upon several species of Epilobium, is rather common 
in Europe. In America only two specimens referred to this species 
are known to have been collected (Holway, /. c). Lind points out 
that the mycelium is perennial in the subterranean portions of the
