WILDEMAN®® he published another fascicle of additions to the flora of 
the Congo, illustrating the abundance of material that continues to be dis- 
covered in that interesting territory. A full list of collectors and stations is 
given, and frequently also full descriptions based upon fresh material. There 
is also included an account of Meliola as represented in the Congo country, 
with descriptions of new species and varieties, and Meliolinopsis is established 
as a new genus. 
ROBINSON,”? in connection with his study of the Bolivian representatives 
of Eupatorium, has described certain novelties of the tribe. New species are 
described in Micania (19), Eupatorium (6), Ageratum, and Alomia, while 
Sphaereupatorium is established as a new genus and credited to Kuntze. In 
the Eupatoriums of Bolivia, 68 species are recognized, 29 of which are endemic- 
In this connection the following statement is made: ‘‘The endemism of 
Bolivia as illustrated by this group is thus about 43 per cent as against about 
55 per cent in Peru and 59 per cent in Colombia. After deducting the 29 
endemic species, there remain 39 Bolivian Eupatoriums which extend to other 
countries. Of these only 18 are known in Peru, while nearly all the others 
are species common to south-central Brazil and northern Argentina. Beyond 
a very few species of wide distribution there is a surprisingly slight common 
element between the Bolivian and Paraguayan members of the genus, although 
Eupatorium is pretty well represented in both of these contiguous countries.” 
Reproduction of Douglas fir forests.—The great importance of the Douglas 
fir forest region may be appreciated from the estimate by MuNGER™ that the 
stand within Washington and Oregon amounts to 560 billion feet of mer- 
chantable timber, while the amount in the adjacent forests of British Columbia 
according to WHITFORD” is not less than 350 billion feet. It seems certain 
that the amount destroyed by comparatively recent fires is almost if not quite
