Ill. ANTHRACNOSE OF YELLOW TOAD-FLAX, 
On June 26, 1901, while passing through a peach orchard 
infested with the common weed variously known as Yellow 
Toad-flax, Butter-and-Eggs, and Ramsted, it was observed that 
some of the plants were dying. Upon making an examination 
of the affected plants it was found that the trouble was due to 
an anthracnose which was attacking the plants near the surface 
of the ground. For a distance of two to four inches above the 
surface of the ground the stems were pitted with elliptical 
sunken spots almost identically like those produced by Colletotri- 
chum antirrhim on stems of the cultivated snapdragon, An- 
tirrhinum majus+ 
Since the Yellow Toad-flax, Linaria vulgaris Mill., belongs | 
to the same family, Scrophulariacew, as the cultivated snap- 
dragon, it is not strange that it should be attacked by the snap- 
dragon anthracnose. However, no case of the kind had ever 
been observed, although we had sought carefully for it. In fact, 
the disease was known only on the snapdragon, hence the fol- 
lowing statement in our Bulletin? 179: “So far as known at 
present, this anthracnose attacks no other plant besides the 
Antirrhinum. Therefore, the florist whose grounds are free 
from the disease will have no trouble so long as he propagates 
only from his own stock or from seed. In such a case the source 
of danger is in diseased cuttings and plants from other estab- 
lishments.” 
Upon the discovery of an anthracnose on the Yellow Toad- 
flax we immediately became interested to know if it was really 
the same as the snapdragon anthracnose. It is important to 
know this, because Yellow Toad-flax is a common weed of wide
