Chinquapins.—Castanea pumila, the chinquapin, is an im- 
portant shrubby species with small nuts, native in the southern 
states and not yet growing in our plantations. This species is 
reported to be blight-resistant to some extent. We were fortu- 
nate, during the fall, again through the cooperation of the 
Division of Forest Pathology, U. S. D. A., in securing a fine lot 
of nuts of this species from Mr. D. A. Bisset, of the U.S. D. A. 
Plant Introduction Station at Savannah, Ga. 
Propagation. Experiments are now under way at the Garden 
and at Hamden in grafting and layering, by which we hope to 
propagate the desirable forms asexually. 
Total Number of Trees Growing.—We have now growing on our 
plantations a total of 398 trees of the various species and hybrids. 
This includes 21 Europeans, 2 yrs. old, still growing in the Garden 
nursery. 
SYSTEMATIC BOTANY

The Classification of Dicotyledons 
The study of flower structures and flower buds, with special 
reference to placentation, has been continued. Miss Maud 
urdy has now drawn altogether more than two hundred species. 
Some of these are incomplete in one way or another but in the 
great majority of cases have much more detail than is available 
in published illustrations. The drawings represent nearly two 
hundred genera, about a hundred families. The work on any one 
flower often cannot be completed at one time, because flowers are 
at a certain stage and an earlier stage is wanted. The time of the 
year that it should be looked for is then estimated. For example, 
the early stages of the buds of early spring flowers must usually 
be taken the preceding summer or early fall. 
The Brooklyn Botanic Garden is laid out by the Engler system, 
which was proposed nearly half a century ago as a modification of 
the Eichler system which is, in turn, a modification of the 
Bentham and Hooker system. At first the information on
