PUCCINIA LATERIPES Berk, et Rav. from RUELLIA 
STREPENS L. 
A report of the success of cultures of this species has been 
published on preceding pages (Jour. Mycol. 9:107-9, May 1903), 
and below are recorded the details of the experiments. It had 
been assumed perhaps on ample grounds, that this species was 
autoecious, but heretofore no experiments in artificial infections 
were on record. It will be found stated in the previous report, 
and indicated in the record below that what might be termed a 
'natural infection’ was induced by placing infected soil or humus 
— old leaves and debris with soil at the base of plants of Ruellia 
strepens on whose leaves and stems abundant teleutospores were 
noticed the preceding season — around the host plants in pots 
in the greenhouse, which were used in the cultures. Besides, 
infections with teleutospores by the usual method of artificial 
inoculations was practiced. In a third set of inoculations ure- 
dospores (obtained in previous cultures) were used. Pro¬ 
nounced success attended all of the experiments, making a con¬ 
clusion entirely satisfactory. That the aecidal form of this spe¬ 
cies has not heretofore been designated by a binomial for con¬ 
venient reference is unfortunate, and therefore the name here 
recorded, Aecidium lateripes, will obviate future inconvenience. 
The following is copied from my note book. 
Exp. 81. 
Exp. 82. 
Exp. 115. 
Exp. 138. 
March 5. Soil and humus from base of Ruellia strepens L. 
known to be infected the preceding year, placed around plants 
of Ruellia strepens L. in three pots grown in greenhouse 
since January 30. Spermogonia appeared (in case of plants in 
two pots) March 23 ; aecidia developed April 1 ; later in 
season very abundant uredospores and teleutospores. 
April 2. Teleutospores from stems of Ruellia strepens L. 
exposed all winter but brought into greenhouse March 5, ap¬ 
plied to Ruellia strepens L., 3 to 10 inches high. Aecidia ap¬ 
peared April 10 ; uredo and teleutospores in abundance in 
May and June. 
April 11. Aecidia obtained in Exp. 82 applied to Ruellia stre¬ 
pens L. Uredo appeared April 25 ; later a quantity of teleuto¬ 
spores. 
April 19. Aecidia obtained in Exp. 82, applied to Ruellia stre¬ 
pens L. Successful (but date lost).

In 1902 Dr. Arthur used material furnished by Rev. J. M. 
Bates, Nebraska, on Chenopodium album L. and obtained aeci¬ 
dia identified as Aecidium ellisii Tr. & Gall. The same collector 
also kindly sent me suitable inoculating material on the teleuto-
