5. Puccinia Panici Diet. The connection of this rust 

 with JEcidium 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 I, 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 one 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 1 1, 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 Rutaceac, and both known to be hosts 

 to an aecidium. Although the conditions were exceptionally 

 favorable, no infection resulted on Xanthoxylum, while Ptelea
