The International Seed Exchange 
Seeking to advance the subject of plant classification from a 
practical as well as scientific point of view, the Garden has, during 
the year, addressed to seventy-five foreign botanic gardens that 
issue annual seed lists three communications regarding these lists. 
The first (January) called attention to the existing great diversity 
of arrangement, and invited discussion as to possible unification. 
In a second circular (July) were printed the main parts of the 
twenty-two replies to the first one. From these it appeared that a 
majority of Gardens preferred an arrangement by families listed 
alphabetically under larger groups. We then submitted three 
questions as to what should be the main groups, and the names 
and scope of families. These communications were suggested 
and prepared by Dr. Gundersen. The object is to establish, if 
possible, approximate international uniformity as to plant families. 
The twenty replies received were published in the third (No- 
vember) communication. It appeared that a majority of gardens 
prefer the groups Bryophyta, Pteridophyta, Gymnospermae, 
Dicotyledoneae, Monocotyledoneae, in the order given. For the 
names and scope of families the Engler system was preferred. 
The responses and results so far obtained are very encouraging. 
Our own Seed List has been rearranged to conform to the major- 
ity wishes, as have also several others of those so far received. 
We intend soon to prepare an index of botanic gardens that 
publish seed lists, and also a list of genera as used in all the seed 
lists, in order to call attention more definitely to the existing dif- 
ferences in usage. 
Alfred T. White Memorial 
An account of the unveiling of the Alfred T. White memorial 
tablet and seat was given in the Botanic Garden Recorp for July, 
1923. As there stated, this memorial was a gift from former 
friends of Mr. White, most of whom had been associated with 
him in one or more of his innumerable works for the public good 
in Brooklyn. The names of the Committee that raised the fund 
and secured the memorial were given in the July Recorp. The 
names of the contributors are given in Appendix 1 of this Report. 
An unexpended balance from this fund, amounting to $3,889.85,
