370 THE FERTILISATION OF FLOWERS. [partir 
The visits of a more miscellaneous lot of insects are attaine 
by the honey being very easily accessible, though protected frox 
rain. It is secreted, as in Campanula, by the upper surface of th 
ovary, where it lies fully exposed and surrounded by the flat lim 
of the calyx. The corolla is cleft to its base into narrow linea 
lobes, and permits the most short-lipped insects to have free acces: 
to the honey; the stamens, by cohering at the base of the anther

to form a ring round the style, shelter the honey from rain, thoug! 
not from insects, which can insert their heads or tongues betwee! 
the filaments which are quite thin and widely separate to their base: 
Drops of rain are excluded from the base of the flower partly b 
the shrivelled anthers which point obliquely upwards, and 
by the filaments. That the larger insects fertilise numerou 
flowers at each visit with pollen from other flowers is effected by 
three other characters conjointly. In the first place, the flowers:
