254 WErEATHERWAX: ANOMALIES IN MAIZE AND ITS RELATIVES 
none of the hundreds of embryos that have been sectioned in a 
study of this phase of development has there been observed any- 
thing to account for this division of the growing points. 
Three or four other in- 
stances of apparently the same 
anomaly have been brought 
to the writer’s attention at 
different times, but opportu- 
nity for satisfactory examin- 
ation has in each case been 
lacking. In one of these, the 
grain bore three stalks. Oth-

If we except the “‘fasci-

reported,* which, being the 
results of fusion of grains, are 
really out of the realm of 
our present consideration, 
there seems to be no case on

In Coix.—The emergence of two plumules and two wctinaks 
roots from one fruit of Job’s Tears (Coix lachryma-Jobi L.) led 
to an examination to determine: whether or not the enclosed seed 
had two embryos.
