old botanists are credited are far more often those of some modern, 
who has not taken the trouble to determine the species intended, or, 
perhaps, even to quote correctly. This is not the place to go into 
details, but it would be easy to give many examples. ‘Those, of 
course, who go to ‘‘ local guide books, county histories, and such-like 
publications " alone for antiquarian botany will meet with innumerable 
errors. We can say without hesitation, that if British botanists would 
study the ante- Linnzean authors more than they do, they would obtain 
much important information both on the distinguishing characters and 
the nativity of species. 
It is almost fault-finding to notice a slight omission in so compen- 
dious a book, but we think the name Davuria (often found in line 6 
of the formula) required definition as a region little known to the ge- 
nerality.of persons; and we should have scarcely considered that even 
Mr. Watson's low estimate of ratiocinative capacity in British bota- 
nists would have necessitated his informing them that “the non- 
Europes plants found in Greenland and America are non-British 
also.” (P. 76.) These are small blemishes in an excellent and useful 
work, which we hope to see finished in good time ; but we would sug- 
gest to Mr. Watson not to introduce into English literature any more 
such words as ** penni-facture " and “ puelline.

of students in all departments of the science. It is somewhat humi- 
liating' that so many promising periodieals have been doomed to a 
short life full of struggles, and that many even of the oldest and most 
important journals are known to be kept up more by the energy and 
devotion of their editors than by the patronage of the botanical world. 
It was under these cireumstances a bold venture when Dr. Rabenhorst, 
iu 1852, originated a journal devoted to a section of Systematie Bo- 
cus and that section not having much favour among scientific students. 
‘Hedwigia’ has however been a success. For sixteen years it
