NOTES FOR STUDENTS 
Cultures of the Uredineae.—The publications of 1912 on cultural work 
with the plant rusts show an increasing tendency in all parts of the world — 
to clear up by systematic efforts rather than by sporadic cultures the problems 
of biological relationships in this group of parasitic fungi. In the Unit 
States, ArrHuR, who for many years has been prominently associated with this 
field of research, reports® six species which either have been shown to be autoe- 
cious or have been connected with their antithetic generation for the first 
time. These are as follows:? Puccinia Lygodesmiae Ellis et Ev. from Lygo- 
desmia juncea (Pursh) D. Don produced teleutospores on the same host 
without the intercalation of pycnidia or other spore forms. Aecidiospores of 
Aecidium monoicum Peck from Arabis sp. produced uredinia and telia on
