EDITORIAL NOTES. 



Mfe. W. C. Werner, of Painesville.Ohio, found, in 1881,specimens of 

 Lactuea Seariola, L., along the L. S. & M.33. R. R., where it has settled 

 down to stay. 



Fascicles X and XI of Ellis' Fungi of North America will be is- 

 sued soon. Fascicle XT is to he devoted to Uredinece, and promises to 

 he very interesting. 



Dr. H. Christ, Rue de TArhre, 5, Basel, Switzerland, is engaged up- 

 on a revision of the European Carices and desires to procure by ex- 

 change or purchase American specimens for comparison. 



Professor Burrill names the bacteria causing the blight of pear' 

 trees, the poison of poison ivy, and the epidemic disease of chinch bugs, 

 respectively Micrococcus amylovoruSf M. toxicatus,ViX\([ M. insectomm. 



II. Pick finds that the palisade tissue of the upper surface of 

 leaves grown in the shade has shorter cells than that of similar leaves 

 grown in the sunlight. In some cases the palisade cells were round or 

 even elongated parallel to the surface. 



Dr. Geo. M. Sternberg, of the IT. S. Yellow Fever Commission, is 

 preparing a work on Photomicrographs and how to make them, which 

 will supply much needed information to those who desire to use this 

 valuable method of illustrating what the microscope reveals. 



Dr. Goodale has imported from Germany a number of pieces of 



"very valuable apparatus for investigations in physiological botany at 



the Harvard botanical laboratory. It is the only collection of the kind 



in this country, and on account of its expensiveness will doubtless be 

 so for some time. 



Mr. Thos. Meehan in observing Stapelia btifonia discovered that 

 the axillary buds, in the normal condition of the plant, produce 

 branches only, the flowers coming only from the weaker lateral acces- 

 sory buds. But when the vegetative power of the plant is weakened, 

 as by drying out, the axillary buds become the flowering ones, 



Mr. II. X. Patterson, of Oquawka, 111., has ready for delivery his 

 first box of North American genus labels, from RanuricuXacece to Com- 

 positce, 650 genera, 3 of each. We have never seen anything more neat 

 and convenient and would most heartily recommend them to botanists 

 as just the thins: to paste upon their genus covers. The set mentioned 

 above costs $1.30. 



The Bulletin of the Buffalo Naturalists' Field Club is 

 the title of anew publication and a most creditable one it is. Nos. 1 & 2 

 are before us and contain among botanical articles, "The Dissemination 

 of nlants,"byMiss Edna M. Porter, and "Adventives in East Buffalo," by 

 J. F. Cowell. The"Botanical Xotes"are mostly written by David F. Day, 

 and of course are very interesting. We wish the new club every success.
