The total number of sheets sent for distribution shows a 
decided increase on that for recent years. Although a new 
Desiderata List has not been issued, members have kept the study 
of critical groups to the fore, and nearly all of these were repre- 
sented by a larger or smaller number of gatherings. On the whole, 
the Referees were satisfied with the material they saw ; though, 
it must be pointed out, that quality to a greater extent than 
quantity is to be desired and especially needed in specimens for 
study. Incomplete and mouldy examples are useless and are 
better destroyed. 
Lt.-Col. Wolley-Dod wishes me to emphasise the importance 
of having gatherings homogeneous in the genus Rosa, and great 
care should be taken that sets are gathered from a single bush 
only. This, of course, applies with equal force to certain other 
genera and groups.
