Javanese woods.—Under the direction of Dr. J. W. Mott, of Groningen, H. 
H. Janssontus has undertaken to describe in detail the structure of a large col- 
lection of the woods of Java,! which was made by Koorpers in connection with 
| his undertaking to prepare for the Buitenzorg Garden a forest flora. KoorDERS 
marked 4000 individual trees, many of them in the primitive forest, and from these 
and others collected 15,000 specimens, which form the basis of the work, Flora 
arborea javanica, by KoorDERs and VALETON. The collection of woods comprises 
2400 numbers, representing 1070 species, 380 genera, and 80 families. 
is made for the complete identification of this material with corresponding her- 
barium material which has been or will be distributed. The descriptive part of 
this work comprises, under each species, references to the literature (an enor- 
mously repetitious method), an account or list of the material, names of the 
preparations (whether cross, radial, or tangential sections, or macerations), a 
list of the reagents employed (why not also one of the tools used ?), and finally 
the micrography, including the topography (which is usually illustrated) and a 
detailed description of the elements. The utmost pains is evident in the attention 
to every detail of organization and of execution; and if such an enormous accumu- 
lation of minutiae is of value to anybody he will certainly find this work a mine 
of them. It is being issued with the support of the Colonial Office. 
Mott desires authors whose work has dealt with the anatomy of woods to send 
him separates.—C. R. B 
Flora of Columbia, Missouri.—The second number of the science series of 
“The University of Missouri Studies” is a handsome and bulky volume on the 
flora of Columbia and vicinity, by F. P. Danrets.? It represents the results of 
the intensive study of a restricted flora for five or six years, and consists of two 
parts bearing the titles “Ecology” and ‘Flora.’ 
Under “Ecology” (pp. 75) “the attempt has been made to indicate the — 
; relationships of the flora; to determine the external factors of these associations 
and to ascertain the rhipstlogica! adaptations of the plants themselves to theie

the composition of the flora, is to be regarded as a finished one; but the experi-
