FLOWERS OF THE HEATHS AND MOORS 



WHORTLEBERRY (Vaccinium Myrtillns, L.) 



globular corolla by the epigynous disk. The aperture is so small that 



only long-lipped insects are able 

 to reach it, such as hive-bees and 

 humble-bees. The flowers re- 

 semble those of the Heath; but 

 the anther- cells are close to the 

 style, resting against the openings, 

 and so retained until the insect 

 visitors disturb it, when pollen 

 falls on the back. The stigma is 

 slightly projecting, and each visitor 

 touches the stigma before it re- 

 ceives the pollen with which the 

 anthers cover it. It is visited by 

 the honey-bee, Bombus agrorum, 

 B. lapidariiis, B. tcrrcstris, B, 

 scriiuskiranus, and Andrena. 

 Vespa rufa is a frequent visitor 

 also. 



The berry is blue or bluish- 

 green or black, and is eaten by birds, and the seeds are thus dis- 

 persed.
