MY STUDIO NEIGHBORS 



We have thus seen adaptation to the thorax, 

 the eyes, and the face in the three examples 

 given. And the entrance of the flower in each 

 instance is so formed as 

 to insure the proper angle 

 of approach for the insect 

 for the accomplishment of 

 '■y]J"-*0^^^^. the desired result. This 



direct approach, so neces- 

 sary in many orchids, is in- 

 sured by various devices 

 — by the position of the 

 lip upon which the insect 

 must alight ; by the nar- 

 rowed entrance of the throat of the flower in 

 front of the nectary; by a fissure in the centre of 

 the lip, by which the tongue is conducted, etc. 



Many other species allied to the above possess 

 similar devices, with slight variations; and there 

 is still another group whose structure is distinctly 

 adjusted to the tongues of insects — adaptations 

 not merely of position of pollen masses, but even 

 to the extent of a special modification in the en- 

 trance to the flower and the shape of the sticky 

 gland, by which it may more securely adhere to 

 that sipping member.
