larly viscous or sticky, a contrivance to keep crawl- 

 ing creatures of the ant kind away from its stamens. 

 Tlie single pistil is much longer than the stamens, 

 and is somewhat recurved. The corolla is slightly 

 bell-shaped, and when a bee, dusted with pollen from 

 a flower previously visited enters the corolla after 

 honey, the j^istil cannot fail to brush his coat, and 

 collect the pollen upon its sticky style. Then the 

 stamens are reached, and a fresh load of pollen dusts 

 tKe bee's coat ; this pollen from its ow^n flower the 

 style does not gather, for its sticky surface is already 

 covered with yellow powder.
