Mycologia 
lister and Mr. Tharp, of the University of Texas, made in No- 
vember, 1914, soon placed in my possession resting telia on Hor- 
deum pusiUiim and dormant bulbs of the Nothoscordium, which 
were made to yield the above results. 
In the meantime it was remembered that ]\Ir. W. H. Long had 
reported this connection several years before. In a letter dated 
Feb. 28, 1904, he says : “ I have successfully grown Uromyces 
Hordei urediniospores from sowings of aeciospores that I find on 
Nothoscordium striatum [N. bivalve].” Again on IMarch 24, 
1910, Mr. Long wrote: “Since writing you last I have cross-in- 
oculated teliospores on Nothoscordium striatum, and aeciospores 
from it upon Hordeum nodosum [error for H. pusillum], and 
got successful cultures in both instances.” Mr. Long kindly sent 
material to illustrate his work and also material with which to 
verify his conclusions. Unfortunately it was not possible to 
bring about conditions for the cultures, and as Mr. Long’s work 
was done in the open, and not verified by others, the results were 
omitted from the North American Flora when this species was 
reached.^® 
In this connection it may be well to say that the statement in 
the North American Flora that the species occurs in California 
on Hordeum nodosum is erroneous. The species ranges from 
Nebraska to Mississippi and Texas, which also includes the range 
of the aecial host, although the aecia have only been taken in 
Texas. 
Summary 
The following is a complete list of the successful cultures made 
during the year 1915. It is divided into two series, species that 
have previously been grown in cultures and reported by the writer 
or other investigators, and species whose culture is now reported 
for the first time.
