more violent explosion occurs. The style lies until this second 
explosion, along the lower part of the carina, and its flattened 
terminal part lies in the apex of the carina above the longer 
anthers which have long since dehisced; when freed from 
restraint it curls inwards, forming more than a complete spiral 
turn (7, Fig. 65). As soon as the split extends to the point where

4.—Ditto, after removal of the ale also.

6 ee after explosion of the short stamens, from the side; the vexillum and ale have been 
removed. 
7.—Position of the parts after complete explosion. 
8.—Staminal tube, slit open immediately to the right of the superior median stamen (1). 
9.—End of the style, from within. : 
pl, flattened portion which expels the pollen; n, stigma. 
the end of the style lies, the style springs up, striking the back of 
the bee with its stigmatic tip; almost in the same instant, the 
greater part of the pollen carried away by the expanded end of 
the style is shed upon the bee’s back, and at the same time the 
long stamens, to which some pollen still adheres, curl inwards and 
issue from the flower. When, as often happens, the bee is so held 
that the stigma cannot slip off at the side but remains pressed
