SHORT NOTES ai | 
flowers are protandrous, the three stigmatic lobes not unfolding 
or becoming receptive until after the pollen is shed. e pen 
dulous habit, in addition to protecting the pollen from rain, 
is also of use in minimising any chance of self-pollination, 
which rarely or never occurs. he flowers are commonly 
tenan y numerous minute insects which may sometimes 
assist in cross-pollination. Flies are frequent visitors, and I have 
occasionally observed Pieris rape sipping honey. e flowers 
appear to be used as hibernacula by various insects in wet weather 
and at night time, a fact previously remarked by Miller.
