GIPSYWORT 



125 



is from 2-3 ft. high. Flowers are to be found in July and August. 

 The plant is a perennial propagated by division. 



The flowers are small and proterandrous in the complete flowers. 

 There are small female flowers. The corolla is bell-shaped, 3-4 mm. 

 long, 2\ mm. wide at the 

 mouth, hardly i mm. 

 wide at the base. The 

 honey is secreted at the 

 base of the ovary, which 

 has a yellow, fleshy base, 

 and can be reached by 

 short-lipped insects. It 

 is sheltered from rain by 

 long hairs which reach 

 from the sides of the 

 corolla to the middle. 

 The unclerlip has purple 

 spots on it which serve 

 as honey-guides. The 2 

 stigmas are still unex- 

 pandecl when the anthers 

 have ripened. As soon 

 as they spread the an- 

 thers wither and are 

 turned down. There is 

 a wide space between the 

 anthers and the stigmas 

 to secure the plant against 

 being self - pollinated. 

 Two of the stamens are 

 rudimentary. There are 

 many visitors, which 

 touch the 2 developed 

 stamens on account of the 

 small size of the flower. 



These visitors include Polistes, Melithrcptus, Syritta, Lncilia, 

 Sarcopliaga, Pollcnia, Hemiptera, several bugs, Lepicloptera, Adda* 

 Thysanoptera, Thrips. 



The nutlets are free, and fall around the parent plant, which is thus 

 dispersed by its own agency, or if they fall in the water by the agency 

 of the water.
