In working out the life-histories of the cedar rusts several un- 
usual species have been found. There are two species which are 
especially worthy of mention. 
t may be said at first that such a large number of the cedar 
rusts have been found to have their complementary stage on the 
c 
considerable surprise that one species has been found which has 
its alternate stage on an herbaceous plant of the rose family, a far 
different host from the woody plants of the apple family. While 
working on the Garden collections during January of 1908, a rust 
was discovered on this rosaceous host (Porteranthus stipulatus) 
and from a study of its form it was decided that it must be asso- 
ciated with a cedar rust. There were two collections of it known, 
one from Perryville, Mo., and the other from Mammoth Cave, 
Ky. It was thought that a trip to one of these places might result 
in the finding of a cedar rust which would be associated with it. 
Mammoth Cave was selected as the better place to visit, as the 
country is in a wild condition, and a subsequent trip there revealed 
a rust on red cedar which was afterwards proved to be associated 
with the rust on the rosaceous plant. 
Most of the rusts of the apple family which are related to the 
cedar rusts have a peculiar characteristic form. There has been 
one, however, from the western coast which was so unlike the 
others that when it was described the remark was made that it 
could not belong to a cedar rust. Recent cultures have shown 
that this assumption was an error and that in spite of its unusual 
form it is beyond question related to a cedar rust. 
t the close of the regular programme, Mr. Norman Taylor 
gave a brief account of his recent trip to the West Indies, a more 
detailed account of which appeared in the speed JOURNAL.
