cating changes assured us that the proposed changes would 
make names stable, but the promise has not been more than 
partially fulfilled. So many changes are confusing and discour- 
aging to the student, and if other writers on Rocky mountain 
botany do not accept the changes made by Dr. Rydberg, the 
confusion will be increased. 
This book should and will cause more careful observation 
in collecting and a re-study of herbarium material; and such 
study will result in many pleasant surprises to the student. All 
students of botany in Colorado and the Rocky mountain region 
will be debtors to Dr. Rydberg and to the Colorado Agricultural 
College for this Flora which brings together the work of so 
many students and collectors; and students too will welcome the 
forthcoming work of Dr. Rydberg on the botany of “‘the whole 
Rocky mountain region.”—Gro. E. OsTERHOUT, Mew Winda- 
sor, Colorado. 
During the summer of 1903 an extensive forest fire raged 
over the ridges to the south and southwest of Los Gatos, burn- 
ing over many acres. In the spring of 1904 on immense patch 
of yellow became visible on the nearest ridge, and inquiry failed 
to elicit any information concerning the plant which produced 
it, since the plant had never been noticed before. Investigation 
showed that it was Monolopia gracilens, the type of which came 
from Almaden, several miles east of Los Gatos. A few plants 
were afterwards seen on a ridge on the south side of the canyon, 
and this year it was noticed sparingly along Steven’s creek, 
about ten miles northwestward from Los Gatos. But the fact 
to which we wish to call attention is that the plant has not since 
appeared in the place where it was so plentiful three years ago, 
nor have other species been noticed which were abundant at the 
same place. Much of the area is now overgrown with scrub, 
and Helanthemum scopartum, a plant not much in evidence at 
first is equally as plentiful as was the AZonolopia, but since the 
Flehanthemum is perennial, it is likely to remain.—ED.
