Lobelia —C. G. Lloyd. (Drugs and Medicines of N. A., ii., pp. 
67-98, continued.) 
A continuation of the description of the structure and medi- 
cinal properties of Z. inflata, and a beginning of that of Z. 
syphilitica is made in this number. 
Maple Leaf Scale. (Rhytisma acerrinum.)—Samuel Lockwood. 
(Journ. N. Y. Micros. Soc., ii., pp. 142-144.) 
This fungus is described as very destructive to the Maples at 
Freehold, N. J. 
Nuclet.—Fixing and staining. —D. H. Campbell. (Bot. Gaz., 
xii., p. 40.) 
The nuclei experimented on were those of the mother-cells of 
the spermatozoids of various ferns. They were fixed by 1 per 
cent. solutions of chromic acid, or by concentrated solutions of 
picric acid or by corrosive sublimate. Staining was accom- 
plished with hematoxylin and gold chloride. 
Papaver.—An American.—Mrs. R. F. Bingham. (Bot. Gaz., 
xii., p. 67.) 
The first indigenous species of this genus was discovered by 
Mr. John Spence in the high mountains of Santa Barbara County, 
Cal., and been named P. Californica by Dr. Gray. 
Physiological Botany is the title of the latest of D. A ppleton & 
Co.’s Science Text-books. The volume is an abridgment by 
Miss E. A. Youmans of Robert Bentley’s “ Guide to Structural, 
Morphological and Physiological Botany,” in order to make it 
conform to the rest of the series and supplement the volume, 
“Descriptive Botany,” by Miss Youmans. The illustrations 
used are the same as those of the original, and were purchased 
from the author. These are not of uniform excellence, some 
being very diagrammatic, especially those illustrating the forms of 
cells, figs. 22-38. After taking a general view of the vegetable 
world, three chapters (191 pp.) are devoted to the tissues and 
organs of the Phanerogamia and Cryptogamia, the remaining 88 
to the Physiology of Plants. The style is clear and simple, and 
the typographical work good, so that this will prove a valuable 
work in those cases where Gray’s Series are too difficult and too 
expensive for class use.
