of Peck is the amphisporic form of Puccinia Caricis. What 
determines the production of amphispores in this species is an 
interesting question, in view of the fact that only twice have 
they been found, and at such a great distance apart. The amphi¬ 
spores in the Colorado collection did not germinate in drop cul¬ 
ture, although the same conditions gave fine germination of the 
associated teleutospores. 
8. Puccinia fraxinata (Schw.) Arth. — A collection of 
teleutospores on Spartina cynosuroides, sent by Mr. Bartholo¬ 
mew from Hill City, Kans., was used to sow April 29, on Frax- 
inus lanceolata, Adelia acuminata and Ligustrum vulgare. Only 
the first host gave results, showing spermogonia May 5, and 
aecidia May 14, the sowing being made on a cut branch placed 
in water in the greenhouse. 12 
9. Puccinia amphigena Diet. — Teleutosporic material 
on Calamovilfa longifolia sent by Rev. Bates from Red Cloud, 
Neb., was sown on Smilax hispida May 27, and began to show 
spermogonia June 2, and aecidia June 10, both in abundance. 13 
10. Puccinia verbenicola (E. & K.) Arth. — Teleuto¬ 
sporic material on Sporobolus longifolius, sent from Red Cloud, 
Neb., by Rev. Bates, was sown on Verbena urticaefolia May 3, 
and showed spermogonia May 9, and aecidia May 20. Another 
collection on same host, obtained near Lafayette, Ind., was sown 
on same species of Verbena May 27, and showed spermogonia 
June 2, and aecidia June io. 14 
11. Puccinia pustulata (Curt.) Arth. — Teleutosporic 
material on Andropogon furcatus, gathered by the writer at Eng¬ 
lish Lake, Ind., was sown on Pentstemon hirsutus and Comandra 
umbellata May 27, with no infection of the Pentstemon, but 
abundant growth on the Comandra, spermogonia appearing June 
2, and aecidia June 14. This result confirms work done in 1903. 15 
12. Puccinia Pammelii (Trel.) Arth. — The cultural 
results of I904 1C were verified by sowing teleutospores from 
Panicum virgatum, obtained by the writer at English Lake, Ind., 
upon Euphorbia corollata. A sowing was made May 26, giving 
spermogonia June 2, and aecidia June 9. 
13. Puccinia subnitens Diet. Teleutosporic material on 
Distichlis spicata, sent from Red Cloud, Neb., by Rev. Bates, was
