Seventeen members have contributed 2020 sheets of plants, 
which is slightly more than last year. The quality of the 
specimens was, on the whole, high ; but there is room for 
improvement here and there. I am quite convinced that no 
good purpose can be served by again commenting on the non- 
observance of rules in regard to the preparation, etc. of the 
parcels and plants. 
Contributors will do well to remember that if possible more 
than the minimum of six sheets should be sent of each gathering. 
Notes and criticism in the Report lose some of their value if 
only a few members receive any one plant under discussion. 
As in recent years, the Referees have seen all the specimens 
of the critical gatherings ; and in this respect we are indebted 
to H. W. Pugsley, H. J. Riddelsdell, the late C. E. Salmon, 
Dr. E. Drabble, J. Fraser, J. Groves, W. H. Pearsall, and 
Lt.-Col. Wolley-Dod. We have also received valuable notes 
from C. E. Britton, W. O. Howarth, J. E. Little, A. E. Wade, 
and J. W. White.
