THE Journal of Botany for May contains several articles of interest to cryptogamists:—Mr. W. B. Grove describes a number of fungi, some of them but little known or new; and the paper is illustrated by two plates.—Mr. S. Le M. Moore has paid special attention to the small class of endophytic algæ, and gives some interesting particulars regarding the structure and reproduction especially of Chlorochytrium Lemnœ. and Scotino-sphœra paradoxa.—Dr. Hance describes, under the name Ptilopteris, a new genus of polypodiaceous ferns; and Mr. J. G. Baker several new species of ferns in the collection of M. Humblot from Madagascar.—Among the minor notes evidence is given that Centaurea Jacea, L., must be regarded as a true British species.
