Proressor L. H. PAMMEL, in connection with an account of Scler- 
otinia libertiana, has published a very valuable bibliography of fungus 
root diseases, containing considerably over 500 titles. The paper ap-

JUNCUS MARGINATUS and its varieties are discussed by Mr. F. V. 
Coville in a recent excerpt from Proceedings of the Washington Bio- 
logical Society. The forms of this widely variable species have been 
variously treated. Mr. Coville separates the species into three forms, 
characterized as /. marginatus (type form), /. marginatus aristulatus, 
and /. marginatus setosus, the last of which has never happened to be 
characterized. Some useful suggestions are also made as to the treat- 
ment of such groups. 
Mr. Witiiam E. MEEHAN’s “Contribution to the flora of Green 
land” has been distributed as a reprint from the Proceedings of the 
Philadelphia Academy. Asis well known, this reports the botanical 
results of the Peary expedition, the collections being made by Messrs. 
Burk and Meehan. Just 100 species of phanerogams and pteridophytes 
are enumerated. The profusion of lichens and mosses is remarked, — 
thirty-nine species of the former, and twenty-eight of the latter being 
noted. : 
THE REPORTS of the State Botanist of New York for 1891 and 1892 
are just at hand. The former contains a revision of the New York — 
species of Ompha/lia, twenty-one in number, besides the descriptions 
of seventeen new fungi. The latter contains an account of the New 
York species of Pleroteolus and Galera, besides the descriptions of 
thirty-seven new fungi. It is stated that forty quarto plates of edible 
(59 species) and poisonous (3 species) mushrooms have been ae 
pared, drawn full size, in color. These are ready for publication, 
gether with suitable explanatory text. Their early appearance 
delight all mycologists and mycophagists. 
Dr. Wo. TRELEASE has been studying the winter condition of om 2 
maples, and also the confused sugar maples.t The treatment of the — 
sugar maples has been so various that the synonymy is badly tangled: | 
Dr. Trelease recognizes three species of the group SACCHARINS 
. namely, A. saccharum Marsh. (A. saccharinum of the Manual) we a 
varieties darbatum (A. barbatum Michx.) and nigrum (A. sacchar ate 
var. nigrum of the Manual); 4. Floridanum Pax., with its variety 4
