plant, arise clockwise in some piants and counter-clockwise in 
others. I think that /scetes affords similar evidence; but I have 
not been able to satisfy myself on this point. 
The rootstock of the yellow waterlily (Nuphar) shows in its 
leaf-scars the order of development of the leaves to be distinctly 
antidromic as between two segments borne by the same stock; in 
the specimen before me the leaf-scars on the mother stock and on 
the right arm of the Y-like rootstock are arrranged in sinistrorse 
order, whilst those on the left arm are dextrorse. The following 
extract from a letter sent by my young friend, Professor Francis 
E. Lloyd, of Pacific University, Oregon, is very interesting, as it 
Sives a connecting link between the antidromy of Liguzdamdbar 
and that of rootstocks,—“I find that Acer circinatum,a plant o 
very singular habit, shows antidromy as between branch and 
branch in dichotomy. Iam not sure of any observations. The 
plant is a shrub or small tree, and branches dichotomously with 
great regularity and the two branches of the Y twist to the right 
and left respectively.” This is precisely as in the rhizome of 
Flelonias. Professor Lloyd promises to report his observations ; 
and I hope he will extend them to other plants on the Pacific 
coast.

New Species of Fungi from Mississippi. 
By S. M. Tracy AND F, S. EARLE. 
In the Buttetin for May, 1895, the writers described a number 
of new species of parasitic fungi, nearly all of which had been 
collected in Mississippi. During the past year we have identified 
a number of additional species, which are described here. Type 
specimens of all are in the herbaria of the authors, and of nearly 
all in the herbaria of the Department of Agriculture, Rutgers 
College, and Columbia and Harvard Universities.
