5. Puccinia Panici Diet.— The connection of this rust 
with AEcidium Pammelii Trel. on Euphorbia corollata L. was 
reported by William Stuart 12 based on somewhat meager but 
seemingly convincing cultures made in 1901. Teleutosporic 
material for the present trial was obtained at Fair Oaks, Ind., 
on Panicum virgatum. It was sown on Euphorbia corollata May 
16, and again May 24, and both sowings showed the most 
abundant results, giving the first spermogonia respectively on 
May 24 and June 1, and aecidia May 30 and June 9. There can 
be no doubt that these two forms are members of one species. 
While at Lafayette the rust is very rare, at Fair oaks it is ex¬ 
ceedingly abundant on both the Panicum and the Euphorbia. 
It is one of the few glumaceous rusts observed by the writer, 
having so nearly an equal display of both the aecidial and teleu¬ 
tosporic forms. The aecidial form having first been published, 
requires the name to be written Puccinia Pammelii (Trel.) 
nom. nov. 
6 . Puccinia verbenicola (E. & K.) Arth.— Previous 
cultures 13 with this species were verified by sowing teleuto- 
spores, from Sporobolus longifolius sent by Rev. J. M. Bates 
from Red Cloud, Neb., on Verbena urticaefolia, May 16, resulting 
in spermogonia May 23 and aecidia May 30. Also another suc¬ 
cessful culture was made with similar material sent by Mr. E. 
Bartholomew from Stockton, Kans., sown on V. urticaefolia 
June 3, showing spermogonia June 11, and aecidia June 18. 
7. Puccinia Windsoriae Schw. — Teleutospores from 
Tricuspis seslerioides Torr., Lafayette, Ind., were sown May 
19, on Ptelea trifoliata and Xanthoxylum Americanum, both 
members of the family Rutaceae, and both known to be hosts 
to an aecidium. Although the conditions were exceptionally 
favorable, no infection resulted on Xanthoxylum, while Ptelea
