nounced form: Osmunda regalis, O. Claytoniana, O. cinnamomea; 
Lygodium palmatum ; Struthiopteris Germanica; Onoclea sensibilis; 
Botrychium dissectum; Ophioglossum vulgatum—the last very 
marked; and in Woodwardia angustifolia to a considerable degree. 
If one is worthy of a name all are, but it would be much better to 
throw all out of the list of “ varieties” and so save confusion.

§ 80. Rhus Toxicodendron, Z.—On page 47, Vol. VI, of “our 
BuLetin it is said: “ Rhus Texicodendron seems to prefer the 
Red Cedar, Locust, and Cherry, and to shun the Pine. Can.any one 
gives us an account of its proclivities to other trees?” Ihave known 
this Poison Vine for years persistently climbing a Persimmon tree 
in the parsonage yard of the Reformed Church, at Keyport, N. J. 
I have for several years watched the habit of this vine among some 
Red Cedars, and trees of the Amelanchier Canadensis ; invariably the 
Poison Vine avoided the latter, and clung to the former, even though 
two old trees, one of each species, so crowded each other, that there 
was not more than 12 inches between them.

§ 82. Publications.—1. Botanical Bulletin, Nov. 1875; Vol. I., 
No.1, John M. Conlter, Hanover, Indiana. We have here the 
first number of a new botanical monthly after the model of our 
own. The four pages are handsomely printed, and contain inter- 
esting notes on Gentiana quingucflora, Lam., Querci near Hano- 
ver, Ind., Aster Nova-Anglie, L., Certain species of the genus, As- 
plenium, and a List of plants collected in.the Black Hills during 
the summer of 1874. The pftice is the same as for our Bulletin. 
We wish the name had been different to avoid ‘confusion. The 
editor remarks: “The New England States and New York are 
well supplied with such means of communication, but we do not 
doubt that there are many interesting finds and notes west of 
those States that are only waiting some such opportunity as this 
to be presented to the botanical world.” So far as this implies that 
the Butietin or Tur Torrey Borantcat Civs is not open to any 
communication of botanical interest from my part of the coun- 
try. as far.as its space allows, it is a misapprehension. The 2d 
and 3d Nos. keep well the promise of the Ist.—2. The Black 
Spruce. by Charles H. Peck, A. M., read before the Albany Insti- 
tute, May 4th, 1875. A full and well written account of this 
useful and magnificent forest-tree, its varieties and the vegetable 
and the insect parasites that injure it, by the able botanist of 
the State of New York. This is the tree on which Arceutho- 
bium grows. “The remarkable fact about this parasite is that thus 
far it has been detected on those spruces only which grow in 
swamps or on or around’ sphagnous marshes.” This is a stunted 
form. “It has not yet been seen on the typical forest spruce.” 
“The Arceuthobium is now known to occur in five counties of the 
State.”—3. Eriste-t-il dans lu Vegetation actuelle des Caracteres
