 the sphinx -moth to be the insect complement to 

 the blossom, and we may correctly infer, more- 

 over, that the flower is thus a night -bloomer. 

 Examination of the flower, 

 with the form of this moth 

 in mind, will show other 

 adaptations to the insect's 

 form in the position of pol- 

 len and stigma, looking to 

 the flower's cross- fertiliza- 

 tion. In some cases this 

 is effected by the aid of 

 the insect's tongue ; in oth- 

 ers, by its eyes. 



In our own native orchids 

 we have a remarkable exam- 

 ple of the latter form in the 

 Habenaria orbicu la fa, whose 

 structure and mechanism 

 have also been admirably 

 described by Asa Gray. 

 All orchid-hunters know this most exceptional 

 example of our local flora, and the thrill of delight 

 experienced when one first encounters it in the 

 mountain wilderness, its typical haunt, is an event 

 to date from — its two great, glistening, fluted
