but very abundant infection on Amelanchier, giving pycnia May 
i8, and aecia October i. 
Another collection on the same host was sent by Dr. Fromme 
four days later from Woods Hole, Mass., and sown May ii on 
leaves of Amelanchier canadensis, giving pycnia June 5, and aecia 
October 27. The results are in accord with previous cultures.^® 
26. CoLEOSPORiUM Vernoniae B. & C. — A collection of Peri- 
dermium carnemn on Finns taeda, gathered at East Lake, Fla., by 
]\Ir. H. E. Stevens, was sown April 13 on Aster panicidatus, 
Solidago canadensis, Euthamia graminifolia, Laciniaria punctata, 
L. Langloisii (the plant obtained from Texas), and Vernonia 
fasciculata. A sparing infection was obtained on the Vernonia 
only, uredinia being first noticed May 8. 
A similar collection sent by the same collector from Gainesville, 
Fla., was sown May 8 on Solidago canadensis, Laciniaria Lang- 
loisii, Elephantopus carolinianus, Amsonia salicifolia, and Ver- 
nonia fasciculata. Although all the hosts used were possible hosts 
for such a Periderminm, yet infection only occurred on the Ver- 
nonia, showing uredinia May 25 in abundance. 
Uredinia from the last culture was sown May 17 on another 
plant of Vernonia fasciculata, with abundant infection, showing 
uredinia May 26. Another sowing from the same source was 
made IMay 28 on Aster paniculatus and Laciniaria Langloisii, 
with no infection. 
The results are in accord with previous cultures,^’^ and add but 
little to our knowledge of the numerous .southern species of 
Coleosporium. 
Successful cultures reported now for the first time: 
The following species have never before been cultivated, in Amer- 
ica or elsewhere, so far as the writer knows. Some of those in- 
cluded in the above list, such as Puccinia vulpinoidis, P. Dulichii, 
P. tosta, and Periderminm fusiforme, might with some propriety 
have been placed here, as not till after the cultures were made 
was their true status as species known.
