Ind., was sown on the same host and on Cicuta macalata, with no 
infection. Last year this rust was sown on two other species of 
Polygonum without infection. Recently the preliminary an¬ 
nouncement of rust cultures for the season of 1903 by Dr. XV. 
Tranzschel of St. Petersburg has been published. He states 
that infection was secured on Geranium, showing that the widely 
•distributed Aecidium sanguinolentum Lindl., commonly found on 
Geranium maculatum in America, is the alternate form of this 
rust. My own observations in the field all go to affirm the cor¬ 
rectness of this result. 
3. Pucci nia on Gar ex Pennsylvania Lam. from Red Cloud, 
Neb., and Fair Oaks, Ind., was sown on Aster paniculatus, A. 
Drummondii, A. prenanthoides, Solidago rigida, S. canadensis, 
Xanthium Canadense, Silphium perfoliatum, Ribes Cynosbati, R. 
aureum, Geranium maculatum, Viola cucullata, and Onagra bien¬ 
nis, with no infection. 
4. Puccinia on Carex gravida Bailey from Red Cloud, 
Neb., was sown on Aster Drummondii, A. paniculatus, Senecio 
obovatus, Boltonia asteroides, Silphium perfoliatum f Ambrosia 
tridda, Xanthium Canadense, Cleome spinosa, Sambucus Cana- 
'■ densis, Ribes Cynosbati, Xanthoxylum Americanum, and Onagra 
biennis, with no infection. 
5. Puccinia on Elynius Canadensis L. from Red Cloud, 
Neb., was sown on Impatiens aurea, Symphoricarpos racemosus, 
and Napaea dioica , with no infection. There are various reasons, 
of which the above is one, for thinking that the rust on the 
several species of Elymus, occurring east of the Rocky Mts., 
which has heretofore been referred to one species really belongs 
to several species. 
6. Puccinia vexans Farl. on Bouteloua curtipendula 
(Michx.) Torr. from Red Cloud, Neb., was sown on Cleome 
spinosa, Physalis lieterophylla, Physalodes Physalodes, Cassia 
Chamaecrista, and Pentstemon hirsutus, with no infection. 
7. Puccinia tosta Arth. on Sporobolus neglectus Nash 
from Red Cloud, Neb., was sown on Oxalis cymosa, Ceanothus 
-A meric anus, Symphoricarpos racemosus, Cassia Chamaecrista, 
Callirrhoe involucrata, Xanthoxylum Americanum, Cleome spi- 
nost, and Aster ericoides, with no infection. 
8. Puccinia emaculata Schw. on Panicum capillare L. 
from Fair Oaks, Ind., was sown on Aster prenanthoides, A. 
Drummondii, Solidago rigida, Lactuca Canadensis, Eupatorium 
perfoliatum, Xanthium Canadense, Ambrosia tridda Apocynum 
cannabinum, Polemonium reptans, Ribes Cynosbati, Onagra bien¬ 
nis, Anemone Pennsylvanica, and Geranium maculatum , with no 
infection.
