expressed his preference that this position be given, not to university men, 
but to some ‘“‘ humble botanist, a lover of nature.” 
Mr. LORENZO N. JoHNSON died at Boulder, Colorado, February 27, at 
the age of 34. He had been in Colorado for a year, hoping to recover from 
the pulmonary trouble which caused his death. He was an instructor in the 
University of Michigan for three and a half years, being especially interested 
in the fresh water algze, and having published several papers upon Desmidi- 
acee. He collected the fungi of Ann Arbor so assidiously during his con- 
nection with the university as to make their collection of indigenous species 
one of the best in the west. His aptitude for systematic and descriptive 
work must have insured a scientific career of unusual attainment. Aside 
from his connection with the University of Michigan he was engaged for 
several summers at Cold Spring Harbor, where he had charge of the instruc- 
tion in botany. 
AT THE LAST MEETING of the Botanical Seminar of the University of 
Nebraska the following papers were presented: The periodicity of flowering, 
by Mr. Clements; Herbaceous vegetation forms, by Mr. Pound; The karyol- 
ogy of the ascomycetes (a review), by Mr. Shear; Organogeny of the genus 
Prunus, by Mr. Bell. The Seminar has had a semester of unusual enthu- 
Siasm and activity. Since the beginning of the college year there have 
been four public meetings in which twelve papers have been read; and 
Symposia upon the laboratory method, phytogeography, and systematic 
mycology have been held. For the present semester six meetings have been 
arranged for, at which eleven papers will be presented; and symposia will 
be held upon histogenesis and physiology. Dr. Trelease will deliver the 
annual address, his subject being “The description of a species.” 
A SECOND BULLETIN of the New York Botanical Garden gives additional 
information as to plans. The many problems that have presented them- 
selves for solution are discussed. The museum building, with a frontage of 
304 feet, with two equal lateral wings whose total completed length will be 
about 200 feet, will give ample space for collections and laboratories. The 
allotment of the grounds is of interest; buildings, with decorative approaches 
| Surroundings, about 25 acres; pines and other coniferous trees (90 to 
100 pApecies) 30 acres; | deciduous trees (about Laeger g 7O acres, nat- 
small trees,
