Dec. 1903 ] Index to Uredineous Culture Experi?nents 245 
secidial and teleutosporic forms were definitely connected by these 
cultures. In the Journal of Mycology (8:51-6), June 1902, he 
reported cultures made in 1900 and 1901—successful inoculations 
in eight cases, four being repetitions of previously demonstrated 
connections, and the complete cycle for four being reported here 
for the first time. Arthur’s third report (cultures in 1902) was 
published in the Botanical Gazette (35:10-23) for January 1903. 
The successful cultures made number eleven previously reported 
and seven reported for the first time. 
In 1902 cultures were undertaken by Kellerman. The first 
case of demonstrated connection was published in the Journal of 
Mycology, 8:20, May 1902, and appeared in the same periodical 
(9:6-13) in Feb. 1903. This showed seven successful inocula¬ 
tions, two of these not having been previously demonstrated. 
The second Report (continuing his work during 1903) detailing 
more extended cultures was given in part in the Journal of My¬ 
cology (9:109-10) May 1903, and the year’s work is reported in 
full on a previous page of this number of the Journal issued si¬ 
multaneously with (and included in) this Index. 
This brief historical outline (some of the items of which 
were furnished by Dr. Arthur) shows that as yet comparatively 
few American mycologists have undertaken culture work to de¬ 
termine life cycles of our numerous species of Uredinese; but this 
interesting and important work will doubtless have shortly its 
due proportion of devotees. It may therefore be a service to 
workers to put on record for convenient reference, all that has 
been done heretofore with American material. The maximum 
usefulness of the Index will perhaps be realized by adopting an 
alphabetical arrangement, and including Authors, Host-species 
furnishing material for inoculation, species of Uredinese used, 
Host-species on which successful inoculations have been re¬ 
ported, and the Uredineous species in their several stages that 
have been obtained by the cultures. Abundant cross-references 
and common synonyms will be found in proper place. No in¬ 
convenience will then be encountered under whatever subject or 
name search is made. 
An explanation for a single item will illustrate the plan of 
the Index and suggest (though it is hoped not necessary) the 
interpretation of the entries. Taking a case, say Dr. Arthur’s 
experiment showing the genetic connection of Puccinia angustata 
Pk. and Aecidium lycopi Ger., we find four entries printed as 
follows: 
(1) Puccinia angustata Pk. from Scirpus atrovirens (Aecidium 
lycopi Ger. on Lycopus americanus). J. C. Arthur. Jour. Mycol. 8:53. 
June, 1902. 
This, as would readily be surmised, means that culture ma¬ 
terial (teleutospores) of Puccinia angustata Pk. taken from 
Scirpus atrovirens, produced Aecidium lycopi Ger. when sown
