Festuca varia, F. arundinacea, F. alpina, F. gigantea, F. violacea, F. rubra

Festuca arundinacea infected R. cathartica, R. utilis, R. dahurica, R. sa

Aecidiospores from Rhamnus pumila infected Calamagrostis varia, and the 
teleutospores from this grass infected R. pumila, R. _ alpina, R. Purshiana, R. 
es alpinum and R. Grossularia, and that on C. glauca infected R. alpinum, the 
reverse sowing being also made in the latter case. The forms of Puccinia on 
these two species of Carex, therefore, belong to the Ribesii-Caricis group of 
KLEBAHN, but the data are insufficient for determining if they belong to any 
of the five species into which KLEBAHN has divided that group. To the hosts 
mi Puccinia longissima whose alternate generations occur on species of Koeleria 
edum the author adds K. valesiaca, teleutospores from that host having 
Sheed Sedum reflexcum. A form of Puccinia from Carex muricata infected 
Crepis biennis but not Taraxacum. It seems, therefore, that this rust is distinct 
from P. sylvatica. Puccinia Actaeae-Elymi is described as a new form with 
teleutospores on Elymus europaeus and aecidia on Actaea spicata. This form 
does not infect Triticum caninum and therefore is distinct from P. Actaeae- 
A — Fischer, which has teleutospores on that host and aecidia on Actaea 
spicata 
ries of infection experiments made by DreTEL” with Hyalospora 
Polypodit on Cystopteris fragilis is the first attempt at cultural experiments with 
yalospora produces thin-walled and thick-walled uredospores, 
and apparently aa rarely teleutospores. Sowings were made on Cystopteris 
both with fresh uredospores and with uredospores that had been left in the 
open during the winter. In both cases infection occurred easily. In the newly 
formed sori thin-walled uredospores were first produced, and these were fol- 
lowed later by the thick-walled form. Teleutospores were not observed. The 
author believes, as a result of these experiments and the rare occurrence of the ©
