the mounted specimens, although these had been kept in alcohol and 
subsequently in glycerin before they were mounted. 
When the winged forms finally make good their escape they carry the 
pollen to other flowers, to which they are attracted by the Brown's bodies, 
for they live on the juices of plants and would consequently eagerly 
suck the sweet contents of these bodies. Thus they would effect 
cross-pollination. 
Becapitulation : The flowers of Sebcea exacoides, and probably of all 
species of Sebcea, are diplostigmatic, the swollen portion of the style being 
a secondary stigma. 
The function of the secondary stigma appears to be in the first instance 
the securing of self-pollination when cross-pollination should not have been 
effected, but it will also increase the probability of cross-pollination. 
The flowers are visited by one or more species of thrips, which obtain 
the saccharine contents of the Brown's bodies by piercing them with 
their mouth parts. On leaving the flower they carry its pollen to others, 
thereby effecting cross-pollination.
