 Brit. The 1. in this sp. are reduced to scales and assim. is chiefly 

 performed by the stems. The fl. has an explosive mech., in general 

 like Genista (q.7)-), but different in detail. The style is very long 

 and there are two lengths of sta., so that pollen is shed near the tip 

 of the keel (where also is the stigma) and also about half way along 

 its upper side. When an insect alights on the fl. (there is no honey), 

 the keel begins to split from the base towards the tip, and presently 

 the pollen of the short sta. is shot out upon the lower surface of the 

 visitor; immediately afterwards, the split having reached the tip, the 

 other pollen and the style spring violently out and strike the insect 

 on the back. As the stigma touches first there is thus a chance of a 

 cross, if the insect bear any pollen. Afterwards the style bends right 

 round and the stigma occupies a position just above the short sta.,
