but very abundant infection on Amelanchier ; giving pycnia May 

 18, 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 n on 

 leaves of Amelanchier canadensis, giving pycnia June 5, and aecia 

 October 27. The results are in accord with previous cultures. 40 



26. Coleosporium Vernoniae B. & C. A collection of Peri- 

 dermium carneum on Finns taeda, gathered at East Lake, Fla., by 

 Mr. H. E. Stevens, was sown April 13 on Aster paniculatus, 

 Solidago canadensis, Euthamia graminifolia, Laciniaria punctata, 

 L. Langloisii (the plant obtained from Texas), and Vernon ia 

 fasciculata. A sparing infection was obtained on the Vcrnonia 

 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, Elcphantopus carolinianus, Amsonia salicifolia, and Vcr- 

 nonia fasciculata. Although all the hosts used were possible hosts 

 for such a Pcridcnnium, 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 May 28 on Aster paniculatus and Laciniaria Langloisii, 

 with no infection. 



The results are in accord with previous cultures, 41 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 Peridermium fusiform e, might with some propriety 

 have been placed here, as not till after the cultures were made 

 was their true status as species known.
