In the rather inconspicuous Goochjera jprocera self-fertilisa- 

 tion takes place by the swelling up of the viscid matter of the 

 stigma beyond its true boundary, till it touches, as seen in 

 Fig. 28, the viscid disk of the pollinia, and spreads into the 

 pollinia chamber. I have no doubt this takes place in many 



other species of Goodyeray and very probably also in our own 

 Highland species, Goodyera repens. Other species which I have

 modifications for securing self-fertilisation. 



To me was especially interesting the purple Arundina, 

 which one might imagine to have become tired of vainly 

 displaying its beauty to wayward and inappreciate butterflies 

 and hues, and had assumed a form that should— let all the 

 glittering humming wings pass heedless as they would— per- 

 petuate a fertile race. 



These instances go to show that the rule that « the flowers 

 of orchids are fertilised by the pollen of other flowers " is not 

 so universal as has been supposed. It is (o be feared that too 

 often^ the interesting cases of flowers observed to be cross- 

 fertilised by insects have been recorded, while those of flowers 

 otherwise fertilised have not been mentioned, so that the law
