at Boulder, Colo., March 27, 1905, on weathered stems. Mr. 
Bethel also kindly sent growing plants of the host and of Chryso- 
thamnus nauscolus. The latter is not a recorded host for P. 
Grindeliae, but for a similar species, P. tuberculous E. & E. A 
sowing was made on G. Sarothrae April 12, which showed yellow 
dots April 21, and numerous open teleutosori May 2. Another 
sowing was made on both hosts April 26, with no infection on 
C. nauseolus, but most abundant infection on G. Sarothrae, 
showing yellow dots May 4, and open teleutosori May 15. The 
yellow dots were investigated, as in the other instances, and 
found to be the early stages of teleutosori, with no trace of 
spermogonia. 
3. Puccinia Solidaginis Pk. — Teleutosporic material 
was sent by Mr. Garrett, collected at Salt Lake City, Utah, on 
Solidago trinervata, April 8, 1905. It was sown on .S'. Canadensis 
May 17, showing yellow dots June 2, and an abundance of open 
teleutosori June 7, with considerable hypertrophy of the tissues. 
Although the yellow dots were not specially investigated, they 
gave the same appearance of being young sori, as in the above 
species of leptopucciniae. 
4. Puccinia transformans E. & E.— Remarkably fine 
teleutosporic material, forming considerable excrescences on 
leaves and stems of Stenolobium Stans (Tecoma Stans), was 
sent by Mr. Horne, who collected it at Santiago de las Vegas, 
Cuba, May 3, 1905. It was sown on two young plants of S. 
Stans May 13, and in both cases gave abundance of spermogonia 
May 29, and of teleutospores June 5. 
Fine material gathered by Mr. J. B. Rorer on the pods of 
S. Stans in the Bahama Ids., at Nassau, New Providence, March, 
1904, was sent for identification. The pods contained many seeds, 
which were planted in the greenhouse, and provided the host 
plants for the above inoculations. The teleutospores of this col¬ 
lection were in good germinating condition. As there were no 
growing plants of N. Stans at hand, they were sown May 20 
(1904) on vigorous young plants of Camp sis radio ans (Tecoma 
radicans), but gave no infection, although the conditions seemed 
particularly favorable. 
Since the cultures were made a study of the characters of 
the species has been undertaken, and the conclusion reached that 
all North American collections, so far as known, belong to P. 
transformans ( P . exitiosa Syd. & Holw.). An original specimen 
of P. transformans, collected in Baja California by K. Brandegee 
in 1893 on Tecoma Stans, has been examined, and found to agree 
with other specimens on the same host from the West Indies, 
and also with the type material of P. exitiosa on Tecoma mollis, 
that is Stenolobium mollis, from Mexico. The species possesses 
considerably smaller spores, with thinner walls and finer sculp-
