open before the flower opens, with their pollen-covered surface down- 

 ward. The style, which is bilobed, lies behind and above the anthers 

 at first, the upper lobe being warty, the longer bent up. The bee in 

 a younger flower first touches the anthers with its back, and then the 

 papillose or warty stigma. Usually the bee's back touching the stigma 

 lies between spots dusted 

 with pollen in the same 

 flower. The end of the 

 style curves down, and the 

 lower division projects 

 between the anthers, and 

 if the pollen is not removed 

 it is then self-pollinated. 



Hemp Nettle is visited 

 by the Hymenoptera 

 Bouibns, Andrena, Melano- 

 stoma. 



The nutlets, which are 

 slightly netted, when ripe 

 fall around the parent plant. 



Hemp Nettle is a clay 

 plant growing on clay soil, 

 or a sand plant growing 

 on sand soil. 



Several beetles, Meli- 

 gethes viduat^ls, M. ovatus, 

 Chrysomela mentkastri, C. 

 fastuosa, a moth, Lygris 

 alchemillata, a Hemipter- 

 ous insect, Eysarcoris 

 me lano cepkalus, and a fly, 

 Ckromatomyia albiceps, are 

 found on it. 



Galeopsis, Dioscorides, 

 is from the Greek gale, a weasel, and opsis, appearance, because the 

 top of the flower is like a weasel's snout. Tetrahit, Dillenius, is from 

 the Greek word for four, because of the four-angled stem.
