tree, which I have found to be the oak, or in one case a hickory, 
and in which the parasitism as seen in section reminds one of 
that of the mistletoe. There are dozens of these organs on the 
bulb-like base which lies among the leaves and the humus made 
by their decay and must be in close contact with them on every 
side. A saprophytic relation is forcibly suggested, and one con- 
nected with beech leaves rather than with the roots of the beech, 
for the association is always with the beech tree. The leaves 
have an acid flavor and the wood is one of the best to yield wood 
vinegar by destructive distillation. The fresh seedlings of the 
beech, also called beech drops, are pleasantly acid to the taste, 
and their large cotyledons are eagerly eaten by children as they 
come up in the spring. It is possible that there is in the beech 
leaves or the mold made by their decay something which suits 
the nature of the Epiphegus. 
Quite frequent in the beech and oak woods was a myco- 
thizal plant, Corallorhiza multifiora. ts mass of toothed, coral- 
like roots are buried much deeper in the soil than the bulb of 
the Epiphegus, sometimes to the depth of two or three inches. 
Many fine examples of these were seen, some with paler, yellow 
scapes and flowers, the color reminding one of &. innata. 
Two introduced plants found in the outskirts of Montague 
proved of special interest. Gypsophila muralis was growing in 
the dry sand of a little used street. It has the habit of Ave- 
naria patula, but a habitat more congenial to A. stricta as seen 
about the great lakes, fur 1 have met with the former only on 
the thin soil of limestone rocks, where it may be accompanied 
by A. stricta, a common plant of the dune region of northern 
Indiana. The other immigrant was Sedum acre. It formed 
dense patches by the side of the street and had spread into a 
adjoining woods, closely covering the ground like a mat, an 
making an excellent sand binder, green and turfy looking. It was 
Occasionally seen in other places about White lake. As a rock 
plant I have found it in Illinois in company with Arenas patula.
