the phellogen. Smaller papers appeared during that period 
from Hiern* * * § oninew species and from Naudinf on the general 
natural history of the cultivated forms. Contributions of 
systematic significance were issued by KurzJ' and Vesque,§ 
the latter working on the lines of Parmentier and pointing 
out many epidermal characters of specific importance. 
The timbers also received the attention of Brandis, j| and 
in more recent times were studied by BrounH and TJrsprung.** 
The last-named botanist has compiled some very instructive 
information regarding the seasonal histological differentia¬ 
tion in the secondary xylem of tropical grown trees, 
including several Ceylon Diospyros species. 
There has been only one publication dealing extensively 
with the Ebenaceae during the present century, this being a 
purely systematic work by Hallierff in 1901. Hallier deals 
with the relationships of the Tubiflorse and the Ebenales 
in a very general way, and from considerations upon the 
morphology of the flowers, fruits, and seeds, together with 
the phyllotaxis of the members concerned, be builds up a 
complicated table intended to show the polyphyletic origin 
of the sympetalous and, apetalous flowering plants. He 
contends that the Ebenales show a cloBe relationship with 
the Anonacese, Scytopetalum, Geraniaceae, Dipterocarpaceae, 
Sapotaceae, and makes suggestive remarks as to their possible 
affinity to the Ancistrocladeae, Convolvuli ceae, Quinaceae, 
and many other natural orders. The contribution is full of
